No display after installing DVD drive

October 9, 2009 at 05:28:34
Specs: Windows XP Home
Hi all, I've recently installed a new DVD drive after my older one on a perfectly working system chewed a disc up.

After installing this new drive I'm getting no beep on startup, no usb recognition and no display.

I've tried resetting the cmos using the jumpers and the video card fan is working but I still can't get anything to work. The DVD drive installed was an IDE drive (the same as the previous one) and my system had no problems before.

Any suggestions would be greatly appreciated since I have a lot of work to do and no system to do it on :) many thanks in advance.

A few possibilities come to mind. First one is that you have the jumper on the new DVD drive set wrong. Look at the old one and match the setting.

Second one is more likely. You may have disturbed other hardware or cables when you were inside the case. Re-seat all cards, cables and RAM.

Hopefully, you unplugged the computer or better yet, shut off the power switch on the power supply, if so equipped.

Did you use proper anti-static precautions when entering the case? Static electricity can build up on your body and discharge into sensitive electronic components. Leaving the computer plugged in but with the power supply off maintains a ground to earth on the case. You can use that ground to discharge yourself just prior to touching anything else inside.

Hi thanks for the quick reply. I grounded myself and yes I switched the PSU off first, I even tried connecting the old DVD drive up and still no display/beeps/usb. I'll try what you said and disconnect everything from the motherboard.

Another thing I tried was removing the cmos battery and resetting the cmos using the jumpers but still no luck.

I'm getting no lights on my mobo but the HDD, video card all seem to be on. The new disc drive is not recognised either. I'll try disconnecting everything again.

Ok just got done with taking it all apart and putting it together again, still no luck. I did everything I possibly could, even removed the motherboard from the system but nothing has changed.

Is there a chance it could be something related to the cables inside my system? or do you think the mobo/cpu could be fried, my only course of action at the moment is to buy a new mobo+cpu but obviously I'd rather not do that if I dont have to.

any help will be greatly appreciated.

Failing power supplies are common and can cause your symptoms.
Check your PS.
They often partially work, fans and hard drives may spin, leds may come on, yet you may get no video and the mboard will not boot all the way.
See response 4 in this:
http://www.computing.net/hardware/w...

The only way to tell for sure is to try a known working PS with your computer. Borrow one if you can and try it before you buy one.

If it is failing, you can usually replace it with any decent standard sized standard ATX PS with the same capacity or greater.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo PS.
See response 3 in this:
http://www.computing.net/answers/ha...

Your power supply must have at least the minumum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD!)
You can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

My graphics card has been fine for almost 6 months now so I doubt this is the case. I was using my computer this morning before the new DVD drive arrived and it was working in perfect order.

I tried my best not to touch anything while changing the drive over and I earthed myself beforehand.

Should I try swapping some power supply cables? or maybe removing the mb battery for a number of hours (if so how many).

Everything is connected fine I just cant seem to figure it out, I dont have a psu handy nor do I have another system I can try the components in.

Please help me someone, I dont want to have to buy another motherboard/cpu combi

Try bench testing the system. Look at response #2 in the link below to learn how.

The chances are about 90% or more you have un-intentionally fried the power supply. In most cases, that's all that's wrong.
Take it to a local place that custom builds or repairs computers and have them test a PS with it.

I don't know if this helps, but I had this same exact symptom and it drove me nuts until I remembered something I had done months before.
More specifically, I had a motherboard with a maximum capacity for 2gb of RAM. I found this out after purchasing 2 2gb sticks of course so I figured I'd see if I could work the bios and get it running with 4gb. I ended up changing some settings and getting it working with the sticks.
This may sound unrelated to the issue at hand, but when I had installed a new drive I must have inadvertently reset the bios to defaults which made the 4gb in the board too much.
This caused the exact symptoms you described. Startup power, lights and LEDs, but no display or actual boot.
It drove me nuts for days until I remembered and pulled out the ram and put 2gb in so it would start up, and was able to adjust the bios again.
Like I said, dunno if that'll help as I don't really know your history with this computer or your level of tinkering. Can you think of anything similar? Anything in the bios you might have changed in regards to voltage?

I do remember increasing the voltage in my bios a while back, not too much though it was still in the "safe" zone. Do you think this could've caused it when I put the new dvd drive in?

I didn't touch anything inside when I put the new drive in, it was a simple swap. Now even putting my old disc drive in doesnt do anything so this is why I'm thinking it could be my PSU.

Do you think my motherboard could be fried as well as the video card and others too? I would try to test my gfx card on my brothers system but I'm worried I might short his motherboard while I'm at it, any tips?


There isnt a local PC repair/building store anywhere near me, my next course of action is to try a new power supply but for all I know the new supply may get fried in the process wasting time and money.

Heeeeelp! :(

Oh also last night I left the cmos battery out and the jumpers in the clear cmos position for about 10 hours, it doesn't seem to have done anything to help.

Just did a quick bench test as mentioned above, only left in 1 memory stick, mobo, cpu, vid card, keyboard and psu. Still no beeps at all.

IF the power supply IS working then surely it's the CPU/mobo at fault? and IF the cpu isnt screwed then it must be the PSU?

I'm almost ready to buy new mobo/cpu/memory/psu because Im worried if I buy a new component it'll get fried with my old hardware.

Any way of testing the PSU is working? My PSU/CPU/GPU fans are all working when I power up but I'm getting no beeps or lights on the mobo.

When you cleared the CMOS did you have the computer unplugged from the wall? If not, you may have fried the board.

The computer was unplugged when the CMOS was cleared. I need to figure out a way to do the following:

- Find out if the PSU is working
- Find out if the CPU/Mobo is working

Right now I'm guessing I may have to buy a new mobo/cpu but if it's the PSU then obviously that'd be cheaper.

If theres a simple way to diagnosing what component is well and truly fudged then it'll narrow it down somewhat. Here is my situation at the moment:

I'm getting NO startup beeps
The mouse lights up for a second when plugged in and turns back off
The DVD drive does not work
Mobo lights dont turn on
All fans working as normal, HDD seems to be working

What I've tried:

- Reseating memory/using only one memory stick
- Disconnecting everything and putting the entire system back together
- Tried to boot with only the CPU/Mobo/Ram connected
- Changed PSU cables

My biggest guess is the new DVD drive somehow blew the power supply or mobo, I remember a few years ago I installed a new CD drive on my old PC and it blew up 2 PSUs before I knew it was causing the problem. Is it possible that this could be the case even though the PSU is still powering the main fan the heatsink fan AND the video card fan?

Like I said before I dont have a PC repair store anywhere near me.

I'm convinced the PSU is working fine:

- DVD Drive works when connected to the PSU
- GPU Fan spins when I turn the power on
- CPU fan spins when I turn the power on
- Hard drive works when I turn the power on

Is it still possible the PSU is broken even with this?

One thing I am concerned about though; the new DVD drive I bought ONLY powers up when the 4pin power connector is plugged into it, if the IDE cable is plugged into it it doesn't power up even if it's not attached to the motherboard on the other end! Could this mean that the IDE port on the DVD drive is faulty and fried my motherboard?

Some advice would be appreciated, my next step is to order a new motherboard/cpu but I'm worried that when I install it the DVD drive will fry it again.

HELP!

The 4 pin (molex) connector IS the power to the drive. It isn't going to run without that. The other cable is the DATA cable.

It is possible the PSU (power supply unit) can still be defective and output some power.

As per #10 above, did you remove the board from the case and disconnect all wiring except as described?

What I meant about the DVD drive was this:

Molex connector AND IDE plugged in - No power to DVD
Molex connector AND IDE plugged into mobo on DVD - no power to DVD
Molex connector in on its own - DVD powers up

I just find it wierd how having the IDE plugged into the DVD drive but not with the other end attached to the mobo stops it from working. To me it seems like the IDE port is stopping the molex from working?

As far as reply #10 is concerned I removed it from the case yes but still no beeps, no beeps even with no RAM in.

I'm quite sure the PSU is fine, I'm guessing I may have somehow fried the motherboard maybe by static charge but I did earth myself.

I would first try a different IDE data cable then.

Do you have ONLY one IDE port on the motherboard?

What happens if the DVD drive is not connected at all?

I'll try a new IDE cable, yeh only one IDE port, the others are SATA. If the DVD drive isnt connected at all the same happens = no motherboard startup beeps or anything.

Could this be a fried motherboard/CPU? Or the PSU?

I'm more of a software kinda guy so I can't really asess the situation that well.

If I can't solve this in a few hours I'll be ordering a mobo + cpu, though I'm worried I may need a new PSU. Do you think I should buy a new PSU too to be safe?

Ok just did some new tests with an old computer I forgot I had. I tried a new IDE cable and the same happened, I then tried my new DVD drive in my old computer and it works when connected to the mobo via IDE, this is making me believe that the motherboard is definitely the culprit. One more test I can try is my brothers power supply on my motherboard just to see if it makes any difference.

Brothers PSU had different connectors and I dont have any adapters to use on it, ah well. I'm still convinced it's the motherboard though so I guess I'll be purchasing a new one today.

You can install an IDE controller care for much less cash than a new motherboard. Look at the link below.

Thanks for the link and the help OtheHill, I'm pretty sure the entire motherboard is fried now, I can't get the mobo lights on, no USB ports work, the graphics card isn't recognised etc. Besides, my mobo/cpu was due for an update, I was running an old AMD Athlon X2 4200 previously so I've decided to get myself something more current as I'm an avid gamer :)

Many thanks to you all for the help, consider this problem sorted for the time being, feel free to lock it though I can reply back tomorrow to say how it went.

Thanks again computing.net forum goers you've been a great help!

"- DVD Drive works when connected to the PSU

YES !

As I said above, failing PSs often partially work, fans and hard drives may spin, leds may come on, yet you may get no video and the mboard will not boot all the way.

Failing PSs are common.
Fried mboards or fried cpus are relatively RARE!
....

"....the new DVD drive I bought ONLY powers up when the 4pin power connector is plugged into it, if the IDE cable is plugged into it it doesn't power up even if it's not attached to the motherboard on the other end! Could this mean that the IDE port on the DVD drive is faulty and fried my motherboard?"

It should never do that.
It's many times more likely the data cable is damaged than there's something wrong with the DVD drive or the mboard IDE controller.

It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittant, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.

Try the DVD drive with another computer.
You may need to try a different IDE data cable.
If the DVD drive does the same thing with any data cable connected to only the DVD drive, then yes, the DVD drive is faulty.

"...I tried a new IDE cable and the same happened, I then tried my new DVD drive in my old computer and it works when connected to the mobo via IDE."

Obviously there's nothing wrong with the DVD drive - if you still had the new IDE cable connected to it, or a different IDE cable than the one that made the drive go off when you connected only one end to the drive, that obviously the IDE cable that made it go off is damaged.


"If the DVD drive isnt connected at all the same happens = no motherboard startup beeps or anything.

Could this be a fried motherboard/CPU? Or the PSU?"

Failing PSs are common.
Fried mboards or fried cpus are relatively RARE!

The chances are about 90% or more you have un-intentionally fried the power supply. In most cases, that's all that's wrong.

Hello again all, just thought i'd report back on how it all went. Basically I got my new mobo/cpu fitted and everything works, my guess is I fried the mobo accidentally when installing the new DVD drive.
