Extreme overheating problems

[Breaks]

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

Hi,

If your temp is 70c then rises to 90c thats way to hot for core 2 duo so this automatically shutting the pc down, I recommend you reseat the the heatsink and put some fresh paste on.

What are you using std cooler and after market!

Don't know what CPU fan you're using but I found this on the website for the Arctic Cooler fan - hope it helps

The BIOS of some mainboard manufacturers compares the speed of the fan with a specified value. If the fan speed does not match the specified value, either the PC emits a warning or switches off. Contrary to the temperature control, the RPM control is of no importance, since fan speeds will be between 500 and 7000 RPM depending o*n the type of fan. This RPM control can de deactivated in the BIOS settings. Please consult your mainboard manufacturer for more information regarding these settings.

In the case of the PC is not booting or immediately switching off, attach the plug of the cooler to the auxiliary power of the mainboard and attach a second fan with higher RPM to the primary power socket. Now the PC can boot allowing the RPM control to be deactivated in the BIOS settings. We recommend using a temperature control instead of a RPM control. The cooler does not need to be removed from the processor for this procedure.

The heatsink isn't meeting the chip properly. Either you have far too much/little thermal paste on there, or the contact is rubbish.

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?

Hi,

Your on off power issues, when you press the power button the fans ect start then stop, few seconds later if that, the pc restarts and stays running!

If the above is the case try updating your BIOS, my media centre pc did the same thing (Asus P5B-WM with 6300) updated to the latest BIOS starts first time.
