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 full screen 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 crummy 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.
