I recently bought and built a new rig, thought everything was perfectly compatible, and when I turned it on everything worked, except the video card.
It doesn't show up in hardware manager, and installing and uninstalling multiple versions of the card drivers doesn't have any effect. I have checked the card by installing it in another pc,
and it worked there, so I know that isn't the problem. I suspect it is a compatibility issue with the motherboard, but that doesn't make sense as as card is a gtx260 and the board has an nvidia chipset.

components if you need them:

video card: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?Sku=E145-0264

motherboard: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?Sku=A455-2422

PSU: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?Sku=ULT-LSP750

processor: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?Sku=CP1-AM2-940

RAM: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?Sku=O261-8038

please help!

P.S. since i think it is an issue with the motherboard, I have looked at getting another one but haven't bought it yet. http://www.newegg.ca/Product/Produc...BYTE GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX
would there be issues since the board has an AMD chipset and my video card is geForce?

The Mobo/GPU combo shouldn't be a problem.
Ultra PSU's are very low quality. Sesonic & Corsair are the best choice for PSU's.
Do a Bench Test

1) Remove EVERYTHING from the case
2) Set the motherboard on a non conductive surface. The motherboard box is perfect for this. DO NOT PLACE THE MOTHERBOARD ON THE STATIC BAG! It can actually conduct electricity! We are going to try and assemble a running system outside of the case.
3) Install the CPU and heat sink.
4) Install 1 stick of RAM.
5) Install the video card and attach the power supply connection(s) to the card if your card needs it.
6) Connect the monitor to the video card.
7) Connect the power supply to the motherboard with both the 24pin main ATX Power connection and the separate 4 or 8 pin power connection.
8) Connect power to the power supply.
9) Do NOT connect ANYTHING else. Make sure you have the power connector on the CPU fan connected.
10) Use a small screwdriver to momentarily short the power switch connector on the motherboard. Consult your motherboard manual to find which two pins connect to your case's power switch. Then touch both pins with a screwdriver to complete the circuit and boot the system.

If all is well, it should power up and you should get a display. Then assemble the parts into the case and try again. If the system now fails to boot, you have a short in the case and need to recheck your motherboard standoffs.

If the system does not boot after this process, then you most likely have a faulty component. You'll need to swap parts, start with the power supply, until you determine what is defective.

thanks for the advice! I'll try it out when I get home and keep you updated.

Alright, so i did a bench test, and the system boot up, but there was still no video. reassembled the components in the case (without GPU) and it ran normally. So I'm thinking my options are

1) RMA my card
or
2) replace the PSU
or
3) switch out the mobo

what do you think?

Hi there,

Is there any chance of you using the PSU from another PC and put it in your new rig as it could be that you need a higher quality PSU.

Out of curiosity I did a bench test using my parent's mobo and CPU
mobo: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?Sku=G452-0013
CPU: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?Sku=CP1-PD-E5200
with my PSU (in my first post) and I got video from the card. could this mean that the PCIe slot is dead?

also I'm going to upgrade the PSU anyways, was thinking this:

they are ok but you would be better of with seasonic or corsair for your power supply since they are the best.

As to your problem, you say the card now works in your parents computer but not yours. Is this correct?

If so then the PCIe slot could have been damaged when you were installing it either by damaging the contacts or by ESD (where you wearing an ESD wristrap or touching the metal of the case and psu whilst installing?)

it could have also got damage by the crappy ultra psu by spiking the PCIe slot.

 

[Schmidtie]

I don't remember touching anything while installing the motherboard, but it is possible. Is there anyway to tell for sure if the slot is dead or not?

 

[greenbrucelee]

put another card in there and see if it works.

you probably didn't damage it but there could have been static electricity (ESD) from you if you were not touch the case and psu regularly or wearing an anti static wristband.

But as I said the most probable cause is the Ultra PSU has damaged it.
