My computer is making very angry, the smallest agitation to the case causes the system to lock up. Small such as me plugging in a usb cable or flicking the case with two fingers. At first I thought it might be that I was overloading my system, Ive got five hd's hooked up (1/2 terabyte) and 5pci cards. I removed 4hds and any cards that werent essential and the computer still locks up if i barely bump it. I dont think its the PS because its about 4mo old. I figure it has to be the CPU or the m-board. But im not sure and hope someone has some insight. If i run a prog that really hogs cpu like counter strike it will lock up then too, otherwise it will run fine till i bump into it. Before this ordeal i used to be able to let my comp run for weeks at a time without having to restart it. Heres the specs Win-xp, 2.4ghz intel, 768mb rambus, radeon 8500 vid card, 350w PS, gigabyte motherboard.
