On my actual System (after latest post of the thread) I get the Error C:\Windows\System32\detoured.dll is corrupt or missing. < Fixed with It occured because of the fault graphics Driver installation over cmd. It crashed again and could only install the .inf at the point where I can use full resolution.
I will find other Problems too soon.
Is the graphics Card broken? Even with installed Drivers I can't run 3DMark at full screen. It works in the background and shows good statistics. But I can't see something. Gonna try furmark later but for what?
Memtest follows tomorrow 4/4 Tests.. But I get no bsod of RAM. Only Maybe System Violations
