AMD display driver stopped responding

[VirtualLarry]

Getting that fairly often now.

PC is a relatively new Lenovo H520, upgraded with a NAXN 350W PSU (single PCI-E 6-pin), 8GB of Gskill Ares DDR3-1600, and an HIS 7790 1GB GDDR5 card. Running Win8 64-bit (pre-installed on a 1TB HDD), and running AMD Cat 13.12. (Was running 14.4, but it had problems with monitor sleep mode not coming back. I haven't had the same problems with 13.12.)

Wondering if card or PSU is going. Both are not very old.

Running BOINC on two cores of the i3-3240, and Einstein@Home on the GPU. GPU temps are 45C right now, so I doubt that the GPU is overheating.

Is anything O/C'd?

When's the last time you dusted out the heatsink on the GPU?

I'd second the recommendation to check the GPU heatsink, but also check your system RAM as well. I had these errors a lot at one point, but taking out the RAM, blowing out the dust, and putting them back in fixed it.

It's amazing how a couple of degree's in temperature can make your previously stable part suddenly unstable.

It may not even seem like enough temp increase to ever possibly make a difference, but the chip could have just barely skated through stability testing as it was.

Nothing is OCed, at least, nothing that I did. (I'm not sure if the 7790 has a factory OC, although I think it's vanilla.)

No dust that I know of, only been running the rig for a few months, everything is fairly new.

GPU-Z reports GPU temps of 45C. I thought GPUs could go up to 90C before they had problems. (At least my old Gigabyte WindForce GTX460 was like that.)

Edit: Thinking I should try a bigger PSU. According to my CyberPower UPS, the rig uses 231W at the wall under full load.

Edit: Could run a few passes of Memtest86+ too, I suppose.

Could be drivers, failing card or failing PSU.

I would try some drivers and see if it goes away. And like someone mentioned if the card is OCed that could also cause it sometimes. And the 90 degree comment you made about it being ok that is true, but it depends on the GPU. Some do go that high (R9 290/X 94) and are ok. Some not so much.

It could be RAM timings,or GPU clocked to high for voltage supplied, or unstable CPU overclock.

I would say RAM timings/IMC on CPU 1st.

I have the same issue with cat 13.12.
However it only happens when I have my Sapphire 7950 OC'd
Default is 900/1250, when I push it to 950/1325 the drivers start to crash
while playing games, causing my monitor to black out for about 5 seconds. Frustrating.

I can only link it to my video card OC. Yes my CPU is overclocked as well, but when I have my video card running at stock, system is 100% stable 24/7

You could try updating drivers to the latest RC version 14.something

Don't feel bad, it happens.

I had it happen to me on both camps, AMD and Nvidia. They will crash when OC.

I think the card is just unstable. I would RMA or return if you can OP.
