Computer Rebooting
Hey folks,
Got a strange problem here with my second pc. A few months ago it all of the sudden started rebooting out of no where. It rebooted while in Windows and also during bootup, so I thought it was a windows problem, but it's not. It even reboots itself while I'm browsing the BIOS or in Linux, or even 2 seconds after I turn it on (before any OS starts loading). So, I thought it was the power supply. I bought a brand new 450 watt one, but it still rebooted. (I've since then moved that power supply to another pc and the power supply works without a hiccup). So, I disconnected all peripherals, removed every PCI card, and put in new memory. But still it constantly reboots. I then even disconnected the cdrom, every hard drive, and the floppy drive....but it still reboots. I also tried plugging it direcly into the wall (bypassing the surge), and tried different power outlets in the house, but it always rebooted. So, I think the problem is either the motherboard or CPU. Do you folks agree (well what else could it be)? And if so, which one do you think it is? Is there a way for me test which one it is? I'm leaning towards the motherboard, but I don't know how a CPU behaves when it fails. Thanks for the help! |

try reseating the CPU, what about memory? 2 sticks? remove one then swap if the problem continues.

Clean it up and reapply new thermal paste or arctic solver, then clean up and reinstall the heatsink/fan. Also, be sure that the fan on the CPU heatsink is working properly. I'm leaning toward the CPU because the system had been working fine but then started to exhibit this symptom suddenly. It could also be caused by residual effects from a past lightning strike near your home... which could have even traveled in through your modem. These are the worst things to diagnose because everything could seem fine for six months after a major storm, but a component that was compromised and is now marginal may suddenly decide to start crapping out on you. :-( |
