Comp died, now without cpu it works.

January 15, 2011 at 12:37:14
Specs: Windows 7
I was ordering an upgrade for my computer. The only old items i had was and old ide dvd drive and a old video card with custom cooler. All the other items was new. After installing the hardware i tried to install windows 7 and failed. When i was going inside the windows log in for first time my computer rebooted. Then weird stuff started to happened, i have the Cooler Master CM 690 Advanced, with the blue led on the front, suddenly when i booted the fan light would blink progressively slower and so did all power related hardware, like the video card etc. It was a progressively slow pulse vibration until it stopped completely.

This is when i gave up for a period of time, the computer would not start. A week later i tried booting it with as few items installed as possible, don`t remember how few items but again after 2-3 hours it died the same way,

But i tried the elimination proses, - OK to get to the point now it starts fine, the computer can run for days, but its without the prosessor, i accidentally broke the fins. I learned that it can be unstable with to much paste, and i had a LOT of it. Its mobo powersupply ram and blue led fan..

I'm sure i can fix this myself, i just need to borrow a CPU to further eliminate the problem. I am not gonna use the old IDE DVD or the video card because i got integrated GPU on the mobo.

But if some super genius has a sixth sense and can give some advise on the above descriptions it would be highly apprenticed.

Don't be too insulted by this comment but you may need some help with that build. You mention at least 4 or 5 errors that you have made.

How did you manage to break off fins on the heat sink?

Sounds like you are trying to boot to an installation of Windows that was installed when different hardware was present. You can't do that without performing a repair installation.

If the original version of Windows came pre-installed on a factory configured computer you probably can't get it to work at all. Those versions of Windows are limited license that are keyed to the original motherboard version.

You need to post ALL the hardware items by full model number, including the power supply.

"now without cpu it works"
"OK to get to the point now it starts fine, the computer can run for days, but its without the prosessor, i accidentally broke the fins. "

Do you know what a CPU - Central Processing Unit - or microprocessor, or processor is ?
It's the large removable integrated chip that's installed directly onto the cpu socket.

Your computer CANNOT run without it's CPU, or processor

A CPU or processor DOES NOT HAVE FINS.

Do you mean you broke the fin(s) off the heat sink that's installed on top of the CPU ? How many of them, and how did you manage to do that ?

If you had to remove the cpu and heat sink as one unit from the other mboard because you couldn't get the heat sink to loosen, doing that can damage the pins on the cpu because you can't release the lever that locks the cpu in the ZIF CPU socket with the heatsink still installed

If you broke the fins off of the heat sink when you were trying to separate it from the cpu, the chances are very good that you could have removed the heat sink BEFORE you removed the assembly from the other mboard if you had done that the proper way.
- if you could, you warm up the cpu by letting the computer run for at least a half hour
- shut off the computer, unplug or switch off the AC power to it.
- release the clamps or screws that hold the heat sink onto the cpu / cpu socket / mboard socket
- remove the cpu fan from the top of the heat sink if that applies
- with the case placed so the mboard is horizontal on a firm surface, press directly straight downwards - hard - on the top of the heat sink, and twist the heat sink back and forth until the bond between it and the cpu is broken
- remove the heat sink
- release the cpu zif societ lever
- remove the cpu

If you use thermal grease - silicon paste with no additives - it's translucent, not opaque, whitish when in a thicker layer, almost clear when in a thin layer - it NEVER hardens, and NEVER glues itself to the cpu as if it were crazy glued to it.

"Its mobo powersupply ram and blue led fan.."{

what comes after that?
........

"After installing the hardware i tried to install windows 7 and failed."

What happened ?

Did you get (an) error message(s) ?
If yes, what was it / were they ?

Provide whatever details you can come up with.

"When i was going inside the windows log in for first time my computer rebooted."

Did Setup complete, then something happened, or did something happen before it was finished ?

Windows is set by default to auto restart when it encounters an un-recoverable error.

You can press F8 repeatedly while booting, do not hold down the key, and select a boot choice that prevents that from happening - if you chose that you will probably see a blue screen message that stays on the screen.
Tell us what text there is on the screen in that message that is unique,


"...suddenly when i booted the fan light would blink progressively slower and so did all power related hardware, like the video card etc. It was a progressively slow pulse vibration until it stopped completely. "

That sounds like a power supply problem.
.......

"...i have the Cooler Master CM 690 Advanced..."

Apparently that's a computer case
http://www.coolermaster.com/product...

"•Front blue LED fan on/off switch
•Cable managment and CPU retaining hole for easy maintainence "

The term CPU is frequently mis-used.
The computer case IS NOT A CPU !
The mboard with the CPU on it IS NOT A CPU !

"Power Supply Standard ATX PS2 / EPS 12V (optional)"

What power supply does it have ?
Make, model, max (output) wattage rating.

What video card are you using ?

No worries, not insulted. I didn't break of the fins of the heat sink, but the ones on the processor(Edit:
pins lol). I forced it into the Mobo so the fins got bent and at least 1 broke off. The processor is useless now. I had a fresh install of windows 7, this version was not limited to a specific motherboard.

Here is the hardware list:

PSU: MIST, 800W, detachable cables
Japanese capacitors, cable kit included (Norwegian brand)

processor: AMD Phenom X2 II 555 Black Edition

I`m from Norway and English is not my native language.., i don`t know why i called it "fins". But i meant the x number of golden metal thin pins that fit into the socket on the Mobo when installing the CPU.

So there is no reason to fixate on the CPU because its not gonna be fixed, the "golden metal thin pins..." are bent. The CPU is not gonna work ever.

"Its mobo power supply ram and blue led fan.."
This is what is running at the moment, right next to me now, the computer is running with the power supply, ram mobo and the blue led light.

I understand that the computer hasn't BOOTED. But the fan gets power and thus; the computers Mobo get stable current from the power supply which was my initial concern.

you can't release the lever that locks the cpu in the ZIF CPU socket with the heatsink still installed

I know this. About the thermal grease i used Arctic Silver 5. I just want to point out that it was 100% my fault the miss understanding. Using the word fins... sorry.

Use a free online translator if you need to - e.g. this one seems quite good:

"....i meant the x number of golden metal thin pins that fit into the socket on the Mobo when installing the CPU. "

Ok then, cpu pins are broken off ?

"...the "golden metal thin pins..." are bent. The CPU is not gonna work ever. "

If any pins are merely bent, then straighten them. You can use something thin and stiff to straigten them - usually they are bent at the base of the pin - place something against the base of the pin and pry opposite the direction the pin is bent towards. You can look at the alignment of the pins bu looking at the cpu from it's sides - when they're all in line, then try the vcpu in the socket.

If pins are broken off, that's another matter, and yes, it's possible the cpu will never work.

"I learned that it can be unstable with to much paste, and i had a LOT of it."

That is probably the cause of all your woes. and given your demonstrated technical ability to date I doubt anyone will let you "Borrow" another CPU for testing purposes.

Thermal paste is used sparingly A small rice-grain sized dab is all that is needed.

You are correct in saying you cannot proceed any further without installing another CPU. You need to decide at this stage whether you are prepared to invest any more money into building this yourself, or seek professional help.

"I forced it into the Mobo so the fins got bent and at least 1 broke off. "

The cpu goes in only one way.You NEVER force it into the socket.
The ZIF - Zero Insertion Force - cpu socket is designed so that when you raise the socket lever beside the socket, the pins will go into their holes easily, if the pins are lined up in the right direction. It shows you in the motherboard manual how to insert the CPU into the socket correctly.

"I had a fresh install of windows 7......"

Did you have it already installed on a hard drive when the hard drive was connected to another computer ? If so, when you connect the same hard drive to a different motherboard and try to boot from that same Windows installation, if the hardware on the second mboard is more than a little different, often Windows will NOT load normally. That can probably be fixed without you having to install Windows from scratch again.

"....this version was not limited to a specific motherboard."

A generic installation of Windows never is - that only applies to using a brand name system supplied Windows disk such as a Windows re-installation disk that came with a brand name computer.

"PSU: MIST, 800W, detachable cables
Japanese capacitors, cable kit included (Norwegian brand)"

That sounds good - it's wattage capacity will handle the system having any video chipset on a card in a slot, or several of them.

"I understand that the computer hasn't BOOTED."

Do you mean "Do you (us) understand that the computer hasn't BOOTED. "

" But the fan gets power and thus; the computers Mobo get stable current from the power supply which was my initial concer"

The fan, or fans, and the hard drive spinning, the leds lighting up, indicates the power supply is at least partially working, but if the cpu is not working, this mboard may never fully boot until you replace the cpu.

Are you getting video on the video card ?

"Mobo: ASUS M4A88TD EVO/USB3-V"

Your motherboard has: "ATI Radeon HD4250 (Hybrid CrossFire)" onboard video - the video adapter built into the motherboard.

It appears there is no information originally in English for your model.

(German)
http://www.schottenland.de/preisver...

select Produktdaten

Grafik-Chipsatz - ATI Radeon HD4250 (Hybrid CrossFire)


Hybrid Crossfire, also known as Hybrid CrossfireX =

it supports both the onboard video and the video on a video card in the PCI-E X16 slot being enabled at the same time, but ONLY if the PCI-E X16 card in the slot has one of a short list of certain ATI video chipsets.

If the PCI-E card has a NVidia video chipset, or if it has an ATI video chipset that is NOT one of the ones that works for Hybrid CrossfireX video, the PCI-E X 16 card will NOT produce video by default, and the onboard video is still enabled.

If you have your computer monitor connected to a video card in the PCI-E X16 slot, if you are getting no video, try connecting the monitor to a video port that's attached to the motherboard.
If doing that produces video, then you can change settings in the bios Setup to enable the PCI-E card's video and disable the onboard video.

If you get no video from the onboard video, then you must replace the cpu.

No i meant that i understand. I know all about the computer analogy, that the CPU is analogous with the human brain.

This was the initial reason for writing on this forum. I wanted to know if it would start normally with fans and everything, because i was impatient with the elimination process.

Great advice, i will try this. Isn't Hybrid CrossfireX very resent technology? I actually use a old ati radeon 2900 pro with custom cooler. I`m not gonna debate any further but instead try all mention advice i have received thus far.

"About the thermal grease i used Arctic Silver 5."

That's not pure silicon thermal grease, that's a thermal compound. It has at least one additive. Some thermal compounds harden as time goes by and the situation can become as if the CPU were crazy glued to the heat sink. Sometimes you cannot remove the cpu from the heat sink when the thermal compound has hardened.
........

Isn't Hybrid CrossfireX very resent technology?

That's probably supposed to be recent - yes it's fairly recent - but some older AMD main chipsets that have onboard video had Hybrid Crossfire support, an older version of the same thing, for say, at least 4 years. The same situation applies for them.

Some NVidia main chipsets have Hybrid SLI support - same thing, for certain NVidia video chipsets on the card.

Intel has some main chipsets with onboard video that have Hybrid Multimonitor support - same thing, for I don't know which video chipsets on the card, however, some Intel onboard video drivers have not had the support for Hybrid video enabled in them yet.

Hybrid video is supported only in Vista and Windows 7.

Searching the Global Asus site with M4A88TD here finds many models, but none of them are M4A88TD EVO/USB3-V

The closest is M4A88TD-V EVO/USB3 - is that what you actually have ?
If so there is an English manual and a German manual - no Norwegian manual.

If the pins are just bent (not broken), carefully straighten them out, then go ahead & use the CPU. The socket is called a ZIF socket, ZIP = Zero Insertion Force. In other words, the CPU should drop right in place. If it doesn't, you probably have it turned the wrong way. 3 out of 4 possible positions will be wrong, only one is right!

Once the CPU is dropped in place & locked down, the heatsink/fan is installed. Before setting the heatsink in place, place a tiny dab of paste about the size of a BB or grain of rice in the center of the CPU - it should NOT be spread around. Then simply set the heatsink on top of the CPU & make sure the metal mounting brackets are positioned over the plastic lugs. Lock the lever in place, plug the fan into the correct motherboard fan header & you're done.

This should all be done BEFORE the board is installed in the case. The RAM should also be installed outside the case. The board should then be benchtested.

Apparently Hybrid Crossfire and Hybrid CrossfireX are the the same thing, but there is an older and a newer type.

ATI Hybrid Graphics
http://en.wikipedia.org/wiki/ATI_Hy...

Excerpts:

"announced on January 23, 2008 with Radeon HD 2400 series and Radeon HD 3400 series video cards supporting hybrid graphics functionality. Originally, ATI announced this feature would only be supported in Vista, but in August 2008 they included support in their Windows XP drivers as well[1]."

E.g. I have an Asus M3A78 Pro mboard. It supports Hybrid Crossfire. If I had a HD 2400 series card, or a HD 3400 series card, it would work at the same time as the onboard HD 3200 video. I don't, so I have disabled the onboard video, and enabled the PCI-E X 16 slot video.

I found some notes I made. Only HD 3470, 3450, 2400Pro, 2400XT work with my Hybrid Crossfire support. The links I saved no longer provide any info

ATI Hybrid CrossFireX™ Technology
The older type.
http://game.amd.com/it-it/crossfire...
.

"Right now the latest generation of Hybrid Crossfire pairs an 890GX or 880G (Radeon HD4290 and HD 4250 respectively) motherboards from the AMD 800 series chipset with an HD 5450 Radeon video card from the HD 5000 Series"

Your mboard supports Hybrid CrossfireX. You have the HD 4250 onboard video . It's probably better than the HD 2900 card video, except for the fact sharing the ram installed in the motherboard with the onboard video reduces the ram's max data transfer rate (bandwidth) by as much as 50%

I borrowed a CPU and stock fan and it was stable and fine in windows until i restarted a few hours later with a lot of new update changes(nothing worked normal so i am gonna install 32 bit now),64 bit may be the problem. I tried the computer playing starcraft, it worked nice with the 4250. It was 30% below medium setting and most setting i set high was cpu depended, but i was very surprised at the graphics being good.

1: the fact that it was 64 bit, windows issues was prob driver related. i am going to install 32 bit to eliminate this at this very moment (will update)

Got error code Error code 0x80070017, need to set to hard drive in the boot order i think..had only dvd drive (new sata drive i am using) Yeah it worked..

Hmm going into windows 7 right now for the first time in 32 bit... seems to be going fine. I am going to install all mobo chipset drives now.

Is there anyway i can stress the computer or anything or am i just gonna have to use the computer for a while to see if there will be issues again?

As I said in response 16....

"You have the HD 4250 onboard video . It's probably better than the HD 2900 card video, except for the fact sharing the ram installed in the motherboard f twith the onboard video reduces the ram's max data transfer rate (bandwidth) by as much as 50%"

The mboard's ram bandwidth is probably the most important thing regarding the max frame rate.

When you have the HD 2900 card installed, the onboard video cannot be enabled at the same time, and the ram on the mboard is able to move data at a max rate as much as twice as much as it was when it was shared with the onboard video.

It's only valid to compare frames per second rates for the same resolution and numbers of colors, doing the same thing in the same program.

On the other hand, I was wrong.
I looked up the max bandwidth of a HD 2900 Pro
- it's very good and probably much better than the 4250 even if it were on a card. .
2900pro / 2900XT 105.6gb/sec with 512mb on the card
2900pro / 2900XT 128gb/sec with 1024mb on the card

"The Radeon HD 2900 XT runs at different clock frequencies in each of its two operating modes, 2D and 3D...."
