Hi,
Im using a radeon 7970 Gpu with windows 8 and the latest amd drivers and whenever I use my gpu for gaming my pc screen will go black and the audio will become frozen. It remains in that state until i hard boot it. I have tried underclocking it and have tried the furmark test. At 85 Celsius it will just crash, i have noticed that my fan only goes to 50 % at that stage so cooling could be the cause. I am using a n 1000w psu so I dont think there are any errors related to power. I just completed installing a new windows 8 onto a new hard disk and before that my Gpu encountered no errors but i do not know how this is OS related.
Thanks for reading
Please Help

Amd Radeon 7970

You said you have all the updated graphics updates..I can assume you have all the windows 8 updates? And what is your voltage for the card being your hitting 85c with an underclock?

Yea I remember windows 7 would have a reduced functionality mode if you don't activate it..don't know the specifics..maybe it doesn't run direct x properly...but again you said you lowered you clock what about your voltage cos voltage has a lot to do with temp?
