Look for the latest DX patch from Microsoft. 293kb one not the 120mb one.

what PSU do you have?

the first thing i would expect is a faulty/weak PSU failing to supply enough power to the system.

ignore the other guys. bad DX install or compatibility issues wont cause a PC to shut down, its either overheating (which you seem to have already found is not the case) or not getting enough power.

that could well be the issue.

i recently was experiencing this exact issue, with my coolermaster 650w PSU. they are not very good PSUs, and mine was failing to supply enough power to my 4890 and shutting off.

do you know anyone who has a spare PSU you could try in your system? im fairly certain that its your issue, but wouldn't want to recommend replacing it until you c an be sure.

I realy don't know what is going on with this issue before 2 weeks i was using the same pc with the same PSU and games but in vista..and when i installed windows 7 exactly on the same day when i played The witcher after 15 minutes just shut down and the problem is that on the previous day i was using the same game on vista and i didn't have any issues this is why i think is not the PSU because if it was the PSU 1)Why is it not turning off in new video games compatible with windows 7 2)why is not my PSU turning off the i'm leaving my pc for days open or running other programs....Maybe it's something else i don't know i will try contract and my suppliers...but realy thanks everyone for the advises i will try find me too the solution and i will reply any news.If anyone has any new ideas on the issue please reply

Check to see if there are any dust build ups on any of your heat sinks. Next thing I would do is open up the ATI CCC and manually set the fan speed to 40%.
