Lately my Xp monitor has benn having these 5 second blackouts wehre the screen will go black for 5 seconds and then coem pack to the preavius picture. IT will do this three times until the screen goes black for about 30 seconds and then the computer reboots it selft. Th emessage i get when the PC restarts is a critical error has occured and it has something to do with my video card. This happens when i run some video games aswell. My card is a GeForce FX 5600, and i keep up with the drivers from the site. Is the card too old?
