new pc build has no picture

Specs: N/A
This is my first post on this forum. I have been
having trouble setting up my new pc build.

The specs are:
amd phenom ii x4 955 black edition
asus eah5770 1gb graphics card
msi 790fx-gd70 mb
8gb corsair dominator ddr3 1600mhz ram

I was wondering how I would be able to set up
the pc without an os installed or any of the
drivers. I guessed that if i just hooked the pc
up to a monitor there would be a bios setup on
the screen or something. I connected it up to
the monitor with an hdmi cable, but there was
nothing on the screen. All the fans start going
and the dvd drive opens/closes. After switching
the pc off I felt the graphics card and it was
hot, and when the pc was on the graphics fan

I have been told that because the graphics/mb
havn't been set up and no drivers have been
installed, there may not be any signal coming
from the hdmi port that I was using, and that it
could be coming from any of the other 3 ports,
which are 2 dvi and 1 display port. I was also
told that I may have to put the graphics card
into a different pci slot.

Do any of these things sound plausible?
Hope I've made it clear

Did you bench test your system ?

No. So bench testing is testing each component one at a
time to make sure they work? How would anything work
unless all the main components are installed (cpu/ram/gpu)?
Sorry if that sounds like a dumb question.

Also, do you think that it may be the port i'm using or the slot
my graphics card is in? Thankyou for your quick reply and
sorry if what I said sounds stupid this is my first build. I have
been searching on google but I can't seem find any relevant
info. I guess it was pretty foolish to not do bench testing.

The purpose of this thread is to demonstrate an easy way to test your system prior to complete assembly. If you take the time to bench test your build prior to full assembly you will save yourself hordes of time in troubleshooting a faulty component.

The most efficient way to minimize lost time is assemble each part one piece at a time until operational stability is proven. The bench build is especially useful when troubleshooting a previously assembled system that has begun to show quirky instability problems, possibly caused by a case short or other similar problem which is hard to detect in an occupied case assembly.

Another major benefit to the bench build is the up-close inspection this method offers you, many times I have torn down a flaky system, bench assemble the parts and notice a burn spot, or debris in the video card slot, small plastic chip type debris has been found in the main motherboard connector which prevents full contact of all the pins in the main connector, another common discovery upon up-close visual inspection is burnt pins in the main connector or cpu power connector on the motherboard.

Well did you test whether you can get a display using the VGA port rather than HDMI?

BIOS usually displays in 640x480 VGA mode so that's where I would begin.

Benchtesting is a very important step. You can save yourself a ton of time if you pre-assemble your hardware outside the case to make sure it works BEFORE installing in the case. Hopefully you read thru the article probfixer posted & you understand it.

A couple of things:

1. why do you have 8GB of RAM? You will need a 64-bit OS to take advantage of that much. If you install a 32-bit OS, less than 4GB will be recognized. Regardless of that, when testing, only use ONE stick of RAM.

2. your video card is PCI-express, not PCI. Your board has 4 PCI-e slots...check your manual to see which is the recommended slot to use when running a single card.

3. use the VGA or DVI port when testing.

4. you didn't list a power supply unit. The PSU is the most important hardware component in the system...everything depends on it. You have some fairly pricey components listed so hopefully you spent a fair amount for your PSU - a decent name brand unit of at least 500W & with plenty of amperage on the +12v rail?

Alright, thanks for your help guys. I have tested the system with
a DVI port. Nothing happened. Also, I do understand the article
that probfixer posted now, so please excuse my ignorance.
I have a corsair tx750w psu. It is a single rail psu with 60amps
on that rail. Do you think it would help if I removed three sticks of
ram and moved my graphics card into the recommended slot?
I have a 64bit os but I haven't installed anything. I can't get
anything to come up on the screen.

Take all the hardware out of the case & benchtest. You should have done that in the 1st place & until you do, it's gonna take forever to determine what's causing the problem. If you can't get the system to boot outside the case, there's no point installing the hardware in the case, right? You could have saved yourself a lot of time & aggravation by benchtesting.

All you need are the following:

- motherboard
- CPU w/cooling fan
- ONE stick of RAM
- video card in the correct slot
- monitor connected by VGA or DVI
- power supply
- keyboard, preferrably PS/2, not USB

If your hardware is good, you should be able to boot, get a display, then enter the BIOS by using the keyboard. You should then go to the PC Health menu & check the CPU temp to make sure it's normal. If it's too hot, remove the cooling fan, reseat it, then check the temp again. Once you're happy with the CPU temp, then you can run thru all the BIOS settings & configure them for best performance. The next step is up to you. If it was my system, I would leave it out of the case, install ALL the RAM, connect a floppy or optical drive, then run memtest86 for an hour or two. If the RAM checks out, install everything in the case & test again, but use ONLY the parts that are listed above. Don't immediately start attaching hard drives, card readers, additional cards, mouse, etc until you're sure the hardware checks out inside the case.

It may seem like a lengthy procedure, but it's better than pulling your hair out trying to figure out what's wrong.

Ok thanks guys I will disassemble my pc and do the bench test. I'll post as soon as I have done it.

Edit: Ok, well, nothing has happened. On the mb there is a 'debug led' which is a digital display which indicates system status by displaying codes. For example, the code 'FF' means 'Power on and first initialize CPU' according to the manual. The codes 'C4' and 'C6' mean 'initialize chipset'. There are lots of codes like this that all indicate different things. My mb displays 'FF', and doesn't seem to get any further than that. Could it be that there is no problem and that I am not waiting long enough? How long should I be expected to wait before I get text on the screen?

If the board has multiple PCIe graphics slots you must use the correct one when using only one card.

Also, do you have the auxiliary power connector fastened to the graphics card?

@OtheHill yes I do have the power connector fastened to the
graphics card, it is a six pin PCIe connector

OK. After doing some research I have come to the conclusion
that there is something wrong with the BIOS. When I switch
on the pc, everything is fine for a few seconds. I know this
because the leds for the numlock and capslock work. Then it
just stops on the FF sequence. It should continue to the next
sequences fairly quickly. I am almost certain that it has
frozen because the numlock led stops responding after a few
seconds. That's why no picture comes up, because it doesn't
get far enough in the boot sequence. I've gone through pretty
much every step in bench testing and everything (accept the
BIOS) seems to be OK.

Is there a way I could fix the BIOS? How can I get my
computer to boot?...........AAAARRG!

U can't boot bcause there is no os in hdd. What is cpu temp?

edit.. If everything is ok,now put everything in pc case and test it again if u pass proceed to instal os,u need to change boot order 1.Fdd 2.Cd rom 3.Hdd, and don't forget to run memtest.

Sounds like a memory issue.

Are you seeing the POST screen or not? You know what that is, right? If you don't see it, you can't "fix" the BIOS.

Let's get back to basics. Check the following:

1. the power supply is connected properly to the board - both the 24-pin main ATX plug & the 8-pin ATX12V plug.

2. the CPU heatsink/cooling fan is properly attached. Fully seated & locked down, with just the right amount of thermal paste used. In the case of the Phenom II X4, it would be just a tiny dap of paste in the center of the CPU. It's described as: "about the size of ¾ of a BB or one and a half uncooked grains of short-grain white rice." The paste should NOT be spread around...just put the dab in the center of the CPU, then install the heatsink.

3. the video card is in the uppermost PCI-express slot, labeled PCI_E1.

You didn't mess with the overclock dial, did you? What about the LEDs...are they lighting up for the CPU & RAM?

"stops on the FF sequence" That indicates that video is there at least for a bit and that I believe that message is memory related.


Are you booting outside the case using ONLY one RAM stick in the first RAM slot?

OK thanks for your help everyone. I am booting outside the
case with 1 stick of RAM in the first slot. The video card is in
PCI_E1. The LEDs are on for the CPU and RAM. I know
what the post screen is, it says FF on by MB. I will check all
my power connections. What I thought was supposed to
happen was when you turn on your system, you would get
codes. I think that FF is the first code. As soon as I turn on
my PC, I get the FF code on the POST_LED screen. For a
few seconds, I will get a response from the numlock LED.
Then it stops responding. Does that mean it is working for a bit? Are you sure there should be anything on the
screen during FF?

BTW there is a 'System LED' for the Chipset. That is on too.
