I recently just bought a ATI Radeon HD 4650 graphics card which ran smoothly for about 4 months. Now, out of nowhere, I get this error message: VPU Recover has reset your graphics accelerator as it was no longer responding to graphics driver commands. I don't know why this is happening, mostly due to the fact that it ran perfectly fine for 4 months then just completely crashes anytime I try to run WoW. It is not overclocked at all and has the latest Catalyst drivers. I also attached a system spec report generated with EVEREST Home Edition.
have you got the latest graphics card drivers installed? what's the idle temp of the graphics card? It could also be a power supply unit fault, what brand and wattage psu are you using? Have you checked in device manager under gpu's to see if it has any errors listed?
I don't know the brand of the PSU but its 375W. The card says it recommends 400 but it worked for about 4 months with the 375 so I thought it would be fine. I have the latest Catalyst 9.9 drivers installed and the idle temperature is around 45 degrees Celsius. It seems to me that its a PSU problem though.
I would upgrade the power supply unit 375w is way to low especially when your playing games it will require more power and if it's a cheap psu it will run not even close to it's stated output. seems to me the gpu is not getting enough power when playing graphics intense games therfor causing it to stop responding. Also you said it worked fine for 4 months but the psu will be under alot of stress therefor causing it to crap out. I would recommed about 500w corsair or ocz or enermax, good quality brands.
Ok I just bought a 550W BFG PSU and it didn't solve anything. I am still getting VPU errors, although it does happen much less often. I can play WoW to some extent now but the video is kind of choppy and the framerate will suddenly drop unexpectedly for a few seconds before crashing to a VPU recover error. I've ran tests and the GPU never goes above 56 degrees while playing WoW and even during a stress test it didn't go above 70.
Could well be a bus problem as well,how many pci-express x16 slots do you have on your motherboard? if you have another switch it to that slot but in some cases the controller mite winge and ask you to switch back to port one. What O/S are you running? does this happen on any other game?
