Symptoms. It will just randomly restart, and then try and post a few times and the boot normally. Then it will randomly restart and be unable to post, the hard drive and power light will just flicker likes it is in a constant restart. Its windows 2000, USB mouse, PS2 keyboard, MSI KM4M motherboard. After consulting with a buddy he thought it might be the ram, which sounded reasonable to me. I replaced the RAM, and all seemed to be fine. Apparently after I left it started again. I've tried running without the mouse or the keyboard and it does no good. Everything is onboard so there are no PCI cards to deal with. Anybody have any experience with this?
