i hav a i3 540 and intel DH55HC mobo! my pc was working perfectly until recently when i booted my pc, it keeps turning off after 2-3 minutes! at first i thought it was a windows problem but i went into the bios and the same problem exists! also when i went into the bios, there are no values for the PSU voltage and temps! my motherboard always showed voltages and temps in the bios but its not showing anymore :/
please help me guys!

Most likely since you've tried just about everything else. Maybe when you have time, breadboard the system meaning taking everything out of the case and assembling it again with the motherboard resting on a non conductive surface.

Taking apart may hint to something, loose plug connections or possibly even a screw wedged behind the motherboard shorting it. Its a drastic measure so not suggesting it willy-nilly.

Turning off could relate to Memory, PSU or Motherboard.

Start with the ram first, trying one at a time if you have multiple of them.

If it still power's off with each one separately, then try another PSU.

Hoping it's just either Memory or PSU, the motherboard will be more hassle obviously albeit memory and PSU can exhibit shutoff behavior and would be your starting points to diagnose.
