Hi all, I'm new here, and know not much at all about computers and the computer terms, so please be patient with me . Well I've been having this problem for a while now. Never really got interested in fixing it until now. I've got a Gateway MFATXPNT ESX 500 P04 running Windows XP Professional. It's got intel Pentium 4(yeah the tower is kinda old). Bassically when I try to turn it on, the button becomes green, but nothing happens. The mother board lights turn on too, but no fan, not hard drive, nada. I tried cleaning the dust out of the fans, but no joy. Anyone got any ideas? Any help would be greatly appriciated.
