iwill xp333-r. powers down right away after booting

[junked]

My Iwill xp333-r system powers down (doesn't even reboot) right away upon bootup.
I see the leds of cdrom and harddrive lighting up, but even before something appears
on the screen it powers down the system. No error bell nothing.

Any idea what could be wrong ? Today after almost a month i powered it on. It came up fine
and was running winxp for almost 30 min before shutting down automatically. Now it is back
to square. Powering down right after power up.

thanks.

Forgot to add system info..
AMD Athlon XP 1600 (AGOIA)
Antec 1030
Savage 2000 Video card.
Netgear 310 Ethernet card.

sounds strange. easiest thing to do is try a different power supply. that's only 5 mins worth of changing, (if you have one on hand) and will work wonders for troubleshooting.

try that and get back to this thread in the morning...

jk, but it's a good place to start anyways!! try that see what happens.

A couple other possibilities: heatsink and CPU core are not getting good thermal contact with eachother (forgot to take tape off thermal patch, or heatsink (and/or heatsink clip) is on 180° backwards), causing it to have a temperature spike which triggers a shut-off. Or perhaps your board needs an RPM-signalling fan on the CPUFAN header.
