I have a friend with a HD 6870 and he has a strange issue where sometimes when watching a YouTube video (I assume other web videos also) his pc will suddenly just display a black screen although his computer is still powered on (all lights on, fans still spinning). He must restart to fix the issue. While gaming and other activities there is never a problem. Note this roughly happens every 70-100 videos he watches but can be more frequent as it seems random. Cannot reproduce error very easily as it doesn’t happen very frequently.
Latest drivers are installed and again the card and computer work perfectly apart from this issue.
Any ideas of what it could be and any potential fix? Thanks.
Well while running games and other things there is no problem so is it likely its his PSU? I will get the specs now and post them soon. Also I am a assuming this is a GPU issue and not something else. I am right in saying that yes seeing what the error results in?
could be GPU working at unstable voltages, check if the PSU can really handle it;
could be driver version bug, try another driver (older ones).
could be overheat, check the gpu temps if they are too high see if the case is well ventilated and check if the gpu coolers are clean.
could be other problems but i bet on one of the above.
out of context but Phenom II x2 555 probably is bottlenecking you performance in games it is a very weak cpu for match with that CPU, i'm not sure if you already know that but it is good looking for a new CPU, and if it requires also a new Mobo and or memory...
