  • Windows 8
  • ATI HD 2x 5770 CF
  • AMD 1055T
  • ASUS M4A89GTD Pro

Specs (complete) :

nothing overclocked.

The following happens randomly(!) throughout the day:

  1. Both screens (Dualscreen) go black and stay that way (turning them on/off doesnt help)
  2. Lights of my CD/DVD drives begin flashing
  3. The PC apparently doesn't shut down though since the ventilation keeps running, so I have to manually force him to reboot.

Seems my PSU was dying. It started making strange noises suddenly and when I replaced it, the other aforementioned problem disappeared as well.
