Stability issues - Even while not OC'd.

[RobotChild]

I've been having some stability issues.
Everyonce in a while, while doing something my PC will just restart.

The last time was while playing Oblivion. Once I had loaded up windows I checked all the temps.
Video card - 48 (VF700-AlCu)
CPU - 40 (7000B-AlCu)
And Ambient - Which was 30

I do not have temps for the northbridge, which I believe where the problem lies.
When I hand-tested the temps on all the heatsinks. The NB was blazing hot.

How much would a Zalman ZM-47J help this? (If it is the problem)

(I'll be picking it up locally. Not TD)

PS - I currently have my AXP 2600+ running stock speeds.

Edit - This is the board.

what kind of power supply do you have? and have u checked the voltages with a DMM?

I'm waiting for a Antec TrueBlue 480W in the mail.

Currently using a YoungYear 350W. I believe it's generic.

I don't know how to check voltages.

i would say your powersupply could be the culprit with your stability issues.
wait for the new one before u go fooling around with anything else.

Would it actually damage any components?
