Right so the motherboard i have is the gigabyte g31m-es2l and i just got myself a new processor. The new processor is a Intel Core 2 Quad Q6600 2.40GHZ 8MB 1066MHZ.

It should work and it does to an extent... for 2 minutes. It all turns on and boots up, then after about 2 minutes, everything just turns off, and i have to switch it off at the mains and switch it back on for it to work again.

I put my old processor back in (it's a core 2 duo something) and it works fine. Help me please?

I am using thermal paste and stuff by the way

Thanks

One thing that came to mind was overheating put if you put the other back and it is ok then I think thats out. I think if you computer needed a BIOS upgrade or it was the wrong type it would have crashed immediately but I could be wrong. Make sure that you don't need a bios upgrade and that the socket is the same. If it was a windows thing putting the old in probably wouldn't help. Could you return it and try another one? Another possibility is an underpowered PSU; check eXtreme Power Supply Calculator. Thats all I can think of.

Overheating issue should be concerned.

Try check with the Gigabyte web site if there is any flash ROM needed to be updated in order to use the Quad CPU.
Be careful with the Bios update though.

Hope this helps!

What do you mean by, "and stuff"?

I am glad you are using TIM, but if not properly applied, it can do more bad than good. See my canned text on TIM.

I tend to put and stuff at the end of things where it's not needed I'm just using the paste and the cooler fan that comes with it. And i apply it by putting a drop on the corner and using a business card to spread it as thinly as possible

I looked on the website and i couldn't find anything about updating the CPU other than updating the bios for more recent CPUs that aren't on the list of compatible processors. But my processor is on the list already.

I'm going to send this back and test another one. My PSU is definatly powerful enough, i have 50W more than recommended.

Thanks for the advice, i'll keep you updated once

That should be good.

Is that based on the manufacturer's stated requirements or what PSC says? How powerful is your PSU?

Just to check, you did remove the old TIM before applying the new didn't you?

I'd say returning it is a good idea because it could be bad.

Based on what the PSC said and it was a brand new processor so i put the TIM on fresh

Based on what the PSC said

The eXtreme power supply calculator only recommends the minimum. And the default settings leave little to no room headroom, so the PSU runs at near capacity 100% of the time. A well designed and well made PSU can handle that, but not without generating some significant amounts of heat. Even the most efficient power supplies are only 80 to 85% efficient. That means for every 100W consumed from the wall, only 80 to 85 watts is supplied to the computer components. The rest is lost, in the form of heat. Budget PSUs are usually around 70% efficient - not good.

If you are not into fan noise, higher temperatures cause PSU fans to run at full speed. Larger capacity PSUs have larger, more efficient heat sinks so a slower turning fan still provides the needed air flow.

Finally, little headroom leaves little room for more RAM, an extra drive, or a better graphics card too. To that end, 50 watts extra is better than no extra so I suspect you are fine. But if curious, below is an extract from my http://www.d-a-l.com/help/general-ha...alculator.html sticky on sizing PSUs.

Plug in all the hardware you think you might have in 2 or 3 years (extra drives, bigger or 2nd video card, more RAM, etc.). Be sure to read and heed the notes at the bottom of the page. I recommend setting Capacitor Aging to 30%, and if you participate in distributive computing projects (e.g. BOINC or Folding@Home) or extreme 3D animated gaming, I recommend setting both TDP and system load to 100%. These steps ensure the supply has adequate head room for stress free (and perhaps quieter) operation, and future hardware demands. Research your video card and pay particular attention to the power supply requirements for your card listed on your video card maker's website. If not listed, check a comparable card (same graphics engine and RAM) from a different maker. The key specifications, in order of importance are:

1. Current (amperage or amps) on the +12V rail,
2. Efficiency,
3. Total wattage.
