I think I damaged my GPU

The system:

i5 4670K
Sapphire R9 290
ASUS Z97-A Motherboard
8 GB G. Skill RAM
650W Antec PSU Gold Certified
256 GB SSD
1 TB HDD
CoolerMaster Hyper 212 Evo

I was stress testing my computer with Prime95 and was getting readings in the mid 90s on CoreTemp. I thought they were a little bit high so I popped open the case to make sure everything was working okay. The 212 was blowing a lot of air toward the front of the case rather than the back, so I thought it was mounted wrong.

Here's where I think I broke something.

I took the fan off the 212 to see which direction the airflow was going. Turns out it was the correct way. I tested this by just plugging in the computer to let the fan run. The computer turned on and off a few times while I was doing this, which I took as a bad sign.

When I put everything back together, the HDMI would not produce a signal plugged into the R9 290. It was working fine before I did my little fan experiment. When the HDMI is plugged into the motherboard HDMI port, all is well. Windows does not detect the R9 290 anymore. I tried reinstalling the drivers with no luck.

The fan still spin on the 290, so it is getting power, it just is not outputting any signal. I've read through a bunch of threads relating to power surges, but I couldn't find much to help.

Any suggestions? I'm really worried I damaged the GPU somehow. Thanks in advance.

Go into device manager and see if your system is recognizing the card.

Also, try putting your GPU in a different PCI-e slot see if that makes any difference.


I've read somewhere that resetting CMOS would help but I don't know the validity of that.

I had the PC off when I took the fan off the 212. I left it outside of the case and still plugged in when I turned it on to see which direction the air was flowing. I didn't unplug or make any changes while it was running. I turned it back off before remounting the fan.

I did take the RAM out while the computer was off as well just before I took the fan off (they were in the way), and left the RAM out when I turned it back on. I reinstalled the RAM when the computer was off.

Maybe 30 seconds or so. It turned off and on itself three times, then I shut it off via the switch on the PSU.

Just reseated the RAM, I'll go see if that did anything. EDIT: nope.

It doesn't show up in device manager. Haha I'd love to try a different PCIe slot but I had to cut into the Antec 300 case already to get it to fit. Darn massive card!

I saw something about resetting the CMOS somewhere too, I'm willing to give anything a shot at this point. EDIT: no luck with CMOS reset

You can reset the CMOS by reseatting the CMOS battery located next to your PCI-e X1 slot while the PC is off.

I would also try a different power supply.
Aaaaaand putting the gpu into another system.


EDIT: Look into your BIOS and see what your primary graphics card is set as. If it doesn't show up in bios I would definitely try a new PSU

I just popped in my old 5770 and it worked no problem using the same cable that I had the 290 hooked up with. Unfortunately the 290 is still too big to fit in the 300 Illusion case which the 5770 was in so I can't test it out in there.

I think it's a safe bet there's an issue with the 290 and not the power supply. :/
