HD4850 Hard Crash While Gaming

post #1 of 4
Thread Starter 
I built a new budget system a couple of days ago. It works well except while gaming suddenly screen goes blank but I can hear the sounds and the game responds to the keyboard. And 10 secs later system completey freezes and I have to manually restart. There is no overclock. I've checked my RAM with memtest and it's fine, cpu did well with prime95. So I think it's either a gpu or a psu issue. My psu is Xilence Red Wing 480 watt with outputs; +3,3V:26 A, +5V:28 A, +5V Standby:2,5 A, +12V(1):18 A, +12V(2):20 A. It should be enough to feed the gpu and on the internet I saw a couple of people running the same combination with no problems. I did 2 hours of stress test with FurMark, gpu hit 90C degrees, but no crash. By the way I have vortexx neo installed on the card, fan speed is at %100 around 2500 rpm. Drivers are updated. Since FurMark uses OpenGL, could it be an issue with DirectX? Would updating BIOS help?

As a side note, Crysis crashes after around 30 mins of playing, Metro2033 crashed after 3 hours, and Dragon Age didn't crash so far.

Update: Just did a stability test with GPUTool and it gave an error in couple of seconds, than screen went black, but came back and Windows said "driver stopped responding but recovered", after a while screen went black again and voila the freeze. Does this mean the gpu is trash?

Try another driver. But I will say that your PSU could also be at fault. Xilence isn't exactly a reputable company, and the 4850 can pull a fair amount of wattage.

Thank you, I will. Do you recommend a specific driver?

Edit: Well the gpu was the problem. I plugged my friends HD4890 to my setup and it worked fine. It passed FurMark and GPUTool tests. Seems like psu is doing good for now. Time to buy a new gpu...
