i have a computer with a pentium 4 nividia geforce 7800 and i think a asus motherboard that sometimes the screen will just go black. could this be from the fact it only has a 250 w psu?
the moniter goes to standby like the computer is going to sleep. when it happens everything else is still running like fans hd. yea got to hold the button turn it off then back on and it will be back to normal.
