Hello from Russia!
My name is Evgeny. I have some problem, my videocard Powercolor 5870 PCS+ it did't work correctly with last AMD drivers (10.11, 10.12 and lastest 11.1). Problems are different - a dark or blue screen, hang with operation IE and Mozilla FireFox, wrong display 2D frequencies in CCC, with driver 11.1 for the first time there was a gray screen with black vertical bands. With driver 10.10 no problems are present. What to do any more I do not know... Cleaned the register, put the driver on pure system but the positive effect isn't present.
Windows 7 x64
Asus Maximus Formula (X38)
4x1Gb DDR2 Corsair Dominator PC-8500
Powercolor HD 5870PCS+
I am moderator of Russian resource Radeon.ru (the best in Russia technical support of ATI\AMD video cards), similar problems meet very often and not only with Powercolor, but also other vendors. What was the such made by AMD programmers? I hope that you will help me to establish the reason of dark blue \grey \black screens.
With best regards, Evgeny!
fist tell me which you use antivirus. maybe your antivirus create it.
i read your post 2 time your problem is very complicated. you put Graphic card and plug another system if work properly then you change our RAM is doesn't work properly you check your Motherboard and Graphic card "resistance and capacitor". if damage you will contact your hardware adviser.
No damages are present, all works correctly on drivers 10.10 and earlier (I already wrote about it).
This problem not only at me, but at many who writes to me on a forum. Something strange happens...
