Computer shutting down after 2 minutes?

Hi. I've been working on a desktop computer and it has a Gigabyte Motherboard installed.

Here is what happens. When I switch on the computer, all the fans on the motherboard will spin extremely fast, I'll get a quick image on the monitor before the computer then turns itself off.

Could this be a motherboard fault or a power supply fault?

I have tested the Ram and that was fine.

The computer was put away a few years ago because it was not needed at the time. The computer was bought in 2009 and was in perfect working order when last used?

I have ordered a new power supply just encase it is the power supply at fault.

If the motherboard is faulty I will have to junk the computer as motherboards are expensive. I could buy a refurbished computer cheaper then what it would cost me for a new motherboard.

Are there any jumpers on the motherboard I could change around or perhaps the processor might be at fault?

What do people think?

    Do you get any beeps, long and short in a formation, basically the PC telling you what's wrong?

    I have had this problem and it turned out the gpu had gone, type the sequence of beeps in yahoo and there you go, this was years ago so I don't know if this still applies, good luck

    Sounds to me like the processor is getting hot. Turn it down (lower the speed settings as if it is a processer that is a little slower), these settings are in the bios and the motherboard manual can help you make these decisions. If the slower speed settings work, then we are right. If not then reverse the settings and continue to check the memory and power supply issues. Temporarily remove all extra devices just to remove them from the equation and make the assessment easier.

    Hard to say. I'm assuming it is appearing to boot up normally and coming up with a log-in screen before cutting out. It almost feels as if the machine is overheating. You may want begin with checking the heatsink to the CPU. (It or the heat-conductive paste isn't making good contact.)
