Computer won't reboot after apparant overheat...please help

by MattMigs / October 16, 2004 2:03 PM PDT

Hey all, I'm new to this site so hopefully I won't irritate anyone by asking this questions. Here's the sequence of events:

1) Intel Active Monitor warns me system zone 2 is overheating (on my motherboard this is near the heatsink)
2) I up the threshhold two degrees...a few minutes later, the system shuts down
3) I try to reboot and though the computer turns on...nothing happens, no BIOS, no windows startup, then shuts down again.
4) I took out the heatsink, reinstalled...gave the comp a break and now power isn't even running through so NOTHING is happening. I've tried a different cable, different outlet, etc...

My question: Does anyone know if my Mobo is dead, CPU is fried, or do I simply need a better power supply...I have a powmax 400W case.


Intel D865PERL board
P4 3.06Gz
1G DDR333 Ram
ATI Radeon 9600
120GB Caviar Hard Drive
40GB Western Digital Hard Drive

is the power supply fan coming on?? - if not you may need a new power supply at the least.
Some power supplies have a fuse which may have blown.
Having said the above its seems there is a lot of over heating of power supply as well as CPU etc because the power supplies they put in computers are barely up to handling the high loads of CPU, graphics and misc hardware.
Place a post in the "computer Hardware" forum and ask for suggestions on a good power supply.

Thanks Pete,
At first I thought it was the mobo but now since there's just NO power getting through, I'm gonna go pick up a new case and see if that'll fix the's the least of expenses I'm worried about.

Just a follow-up:

Bought a 500W power supply, everything seems to now be working fine with the exception of the CPU fan which isn't working...hopefully I just need a new one as opposed to a motherboard problem.

have a HSF that the fan works on. You can fry the CPU in seconds.
