Hi,
1. Im from germany so excuse my bad english:D .
My Problem is that Every time i play a newer game like: Dark MEssiah, The Witcher or Juiced2, my screen turns green after a while of playin.
A ScreenShot.
And that are the tempratueres:>click<
My System is:
>MB: ASRock dual vista 775<
>CPU: INtel core 2 Duo 56300<
>Graka: Geforce 7600gt<
>Ram: 2gb GEIL<

Somebody has told me that it could deal with the
PSU (hope its the right word i mean this thing wich gives the System the energy) so ife bought a new one but the problem is still there.
Hope somebody can help me.
