You guys are my last hope literally, before I have to replace my motherboard/CPU/RAM and Graphics Card.

When I start OpenGL Programs in fullscreen and the same resolution as my desktop, my computer reboots. It is not a Windows shutdown, it just reboots instantly. It also happens sometimes when Windows asks for admin rights. But with OpenGL Programs, this is reproducible. Also happens with programs I write myself or with games. Does not matter.

This happens only with Catalyst 11.8 or newer. It does not happen with 11.7.

I already replaced my PSU with a Corsair TX650V2, because many people told me that this may cause the issue. But obviously it didn't. I replaced my old, really shitty PSU with the new one and still have the error. I am sticking with the 11.7 drivers for now, but it bugs me. Maybe something is broken and my PC about to die.

Memtest completed without errors.

  • motherboard: GIGABYTE ga-ma78gm-s2h

  • RAM: Corsair 4x 2GB DDR2

  • hard drive: 80GB SATA Matrox

  • Graphics: Sapphire Radeon HD4890 1GB GDDR5

  • CPU: AMD ATHLON 5600+ X2, 2.7ghz per core

Have you disabled Restart on System Failure? pcsupport.about.com/od/windows7/ht/… –  James Dec 2 '11 at 17:02
    
Yes, of course. And there is no event entry. –  user107870 Dec 2 '11 at 20:43
