i have a pc that restarts randomly, but when this occurs, nothing on the pc is working except the motherboard light turns on and the case power light turns on. i think it might be hardware problem, any ideas? i have checked all the cables and no problem. i have also brought a extra hard drive but after installing that it still causes the same the problem. i reinstalled windows xp but still the same problem. please help!
windows xp pro sp2
asus p5gd2 deluxe mobo
intel p4 630 3.2 processor
nvidia 6600gt graphics card
old maxtor 300gb diamondmax 10 hard drive
new seagate 250gb baracuda sata hard drive
ultra 500w power supply
