Extreme overheating problems

hey all

I have recently purchased a new system, that has been switched on for first time today, and after around 2 minutes, the computer seems to switch itself off.

Initiallly I thought it was power suppy issue, because when I switch it on, the computer powers up for only a second, then powes down for a second, then it stay powered up until overheating occurs.

Is this normal for a power supply?.

Key component specs are:

Intel core 2 duo E6300 (not overclocked), Gigabyte GA_965P_DS3 Motherpoard and my power supply is EZCOOL PS-900 700 watt version 2.2 tornado.

At a hunch, that it could possibly be overheating, so I managed to, when booting , to gain access to my bios and check hardware monitor (cpu temp), after 10 seconds of being on , the proccessor read at 70 degrees and in space of 5 seconds climbed to 90 and then shut off. What could cause the proccer to rapidly overheat when sitting idle after 2 minutes boot (no operating system installed)

Is the power supply switching on and off related to temperature climb, any help or comments would be greatly apperciated.

Tomorrow I plan to set up the computer components out of the case on a desk, just to make sure that the case is not shorting out the computer. I also plan to re-seat the heatsink and processor, what else would you suggest I try, other then this.

Thanks fror reading

That's an odd power issue, but I don't think it has to do with your overheating problem... How is the CPU cooler installed? Is it a stock one? Did you use thermal paste or a pre-applied thermal pad?
 
Thanks for the response. Yes it is stock retail heatsink that was provided, as well as the thermal paste that was provided, when purchased the processor.
 
I have a X6700 and the thermal paste was on the cooler already and I didn't have to apply anything. You have to make sure that the heatsink is in contact with the CPU, my CPU with stock is around late 30s to 40s depending on the season. so idle of 70 is a bit high.
 
Built my machine out of the case on a desk, re-seated cpu and now temp readings are fine, what I think it was is that the heatsink wasnt seated properly resulting in it not coming in contact with processor.

Ive got a new psu (different from psu previously tried), im still having the on/off power issue at start, it doesnt effect computers booting, however im a little worried about it.

Do you have any ideas why it would do such a thing?

I rang up a engineer from company who i purchased components from, and he said it could possibly just be a sticky power button, i tried one from another case and problem still occured.

It only happens on first power up, however if i restarty myself, or keep my finger on power buttoin for a few seconds it switches off band then i switch it back on it doesnt occur.

Any ideas?
 
It can either be the thermal management of your motherboard kicking in or like the engineer said a sticky start button. The default action for holding down the start button is cutting the power. Hmmm, that is a weird problem.
