HELP! My graphics card boots in my friend's computer but not in mine.

[skessler]

Like the post says, I am having problems with my GPU. when I press the power button, everything in my computer seems to turn on and work fine, except for my graphics card which appears to be trying over and over to start up. Its fans will run for about ten seconds, then stop and start up again. During all of this nothing shows on the monitors. It does this over and over again until I force power off.

Due to the way it was acting, I was almost certain the problem was my graphics card, however, when I plugged the same card into my friend's computer, it booted up just fine.

My computer ran fine since I built it about a month ago, and suddenly the other day it froze in the middle of a game, and when I turned it off and back on, the problems I described began occuring.

I don't have extra RAM cards to test with my computer, and I cannot test my cards in my friend's computer because his motherboard uses old PC2 RAM instead of DDR3. However, I tried booting my computer with each of my 2 4GB cards individually, and my GPU acted the same exact way.

Does anyone know what else the problem could be? Is the only other option that my motherboard is bad? My build is only about a month old and I was extremely careful with all the components so I really don't think I damaged anything. Any help/ideas would be appreciated. Thank you.

EDIT:
Here's my specs:

Motherboard: Gigabyte GA-970-UD3P socket AM3+
CPU: AMD FX-6350 Black Edition 3.9GHz 6-Core socket AM3+
RAM: Ballistix Sport 8GB DDR3-1600 (PC3-12800) CL9 Dual Channel Memory Kit (2x 4GB)
HDD: Western Digital Blue 1TB 7200 RPM SATA III 6.0Gb/s
GPU: AMD Radeon R9 270 Double Dissipation 2GB DDR5 PCIe 3.0x16
Power Supply: Corsair Builder Series CX500

Okay, so I have officially done all of the following:

Replaced the PSU
Replaced the motherboard
Replaced the CPU

(all of the above with brand new, out of the box components)

Ran the system outside the case
Ran the system with each stick of RAM individually, trying each different slot.
Tested my GPU in another system (with a 250W power supply, if that matters, and the GPU worked)

I am completely out of options. It seems like every single component works fine on its own. I'm getting extremely frustrated because I feel like I've gone through every possible problem. Have I missed anything?

A full Windows clean install. Latest bios and drivers.

Need more specific info,

What do you mean with this?

Replaced the PSU = You run it with old MB and old CPU?
Replaced the motherboard = You run it with old PSU and old CPU?
Replaced the CPU = You run it with old MB and old PSU?

Or you running all that + your old graphic card and can boot normal?

Have you tried to replace just your CPU?

Is that possible if I can't get a signal to my monitor?

No I have not tried the new CPU with the old PSU, but I think I've gone through all the other possible combinations. I will try that today.

What connection are you using to connect the monitor to gpu? Ans are you sure you have the monitor on the correct input setting?

 

[skessler]

I had two monitors connected, one DVI-D, and the other VGA connected to a DVI port via an adapter that came with the card. Both monitors were working fine and suddenly stopped working when the issue began, and I haven't changed any settings.

Just want to add, if you have not done this yet then you better don't , if your MB is broken and you use it with the new CPU, your CPU can get insta-kill. So it will hard to detect after that when you change your old MB with the new MB + new CPU if the CPU already get killed. Im not trying to scared you but it's true.
If you alredy done old MB + new CPU you might want to consult to where you bought it to check your new CPU wether it's still work or not.
Btw let us know if your PC can boot up normally again.

Hey guys, I think I was a bit hasty when I said that replacing the CPU didn't help. I think that after I replaced the CPU, my frustration got the better of me and I shut the thing down before it had a chance to completely start up. Because last night (after changing since I replaced the CPU), I hit the power button and it all started up. It seemed to take a few extra seconds (maybe the boot order changed because I reset the CMOS), but it's all working! I am running the system with the new CPU, the new PSU, and the original motherboard and RAM.

I bought a new CPU in the process of troubleshooting, but I plan to RMA the original one. Does anyone have any idea why my CPU may have stopped working in the middle of a gaming session? Is it possible my PSU spiked and caused damage? Some people in this thread have mentioned that the Corsair CX are not exactly top of the line. The new PSU I'm using now is identical to the old CX500, so would it be worth it to buy one that may be higher quality to avoid another problem?

Anyway, I can't thank you guys enough. You guys walked me through the troubleshooting process and probably saved me at least a hundred bucks over taking it to a repair shop. (They were asking for $70 for diagnostics plus $30 per half hour of labor!)

Glad to hear that
Btw for the PSU i would say its decent PSU. If you can afford the better one , why not?
PC is a complicated hardware and one component can impact to another component. We can just assume, if there is no proof that the PSU is the culprit
