graphic driver crushing in vista x64

[bastic]

Hey all...
I have this anoying problem...While I play, sometimes my monitor goes to power save mode and then after few secs picture goes back..when i switch back to windows, i got this info that my graphic driver crushed and got recovered. And another thing that is happening, is that my video playback stops for few secs while watching movie (not even in fullscreen mode, and i can hear sound of it going as normal) and then it comes back again(maybe not an GPU issue??)...
any ideas what that could be ? I dont think it is overheating of my GPU as its fan runs on 100% while I play games...
Thx for any advice.
Oh...i use catalyst 8.1

Are you OC'ing the GPU at all?

 

[bastic]

yes, but just a bit...

Does it do it when you run it at stock?

Sounds like overheating to me. Try removing your overclock and getting the latest drivers. My fan never runs at 100%

ok,I will go down on it....i have to set it up on 100% while I play in 1900*1200 and all details on max,otherwise GPU just switches off(I think its memory overheating) and monitor goes to powersave and doesnt come back. fan on 100% solved that problem doh...but I will downclock it and let U folks know if it helped but i have small problem with getting in to safe mode on vista, while my keyboard doesnt work at the begining of vista loading(its a mac keyboard)

Well you can go into safe mode by typing 'msconfig' in the command line on vista and tick 'select safe boot'. Click ok and then reboot.

Thx

any suggestions

Check in event viewer to see if there is any more info about the error?

Update DirectX and drivers with the newest updates?

Check if there have been any reports of problems between your mobo and graphics card or BIOS update that sounds like it would fix it (unlikely but never know).
