Power off issue

Hi,
I have a PC that randomly turns off, after 5-60 minutes of use. It could be because of the heat, in summer it does this power off thing more often compared to winter. But the PC didn't do this a year ago and it is 3-4 years old. I'm checking the temperature (with HWMonitor) and nothing is above 60-65C, 140-150F).
Is it possible that some sensor could be damaged because of the heat and now it doesn't show anything?

My PC setup:
Intel Core2 Duo E7600
Gigabyte G41MT-S2
2* Kingstone DDR3 4GB
Asus ENGTS450 DirectCU 1Gb D5

As i said, it used to work perfectly for 2-3 years and i have the same hardware (well, i bought a stronger CPU cooler and +4Gb ram for the 2nd slot). And i still play the same game, use the same OS tho...

  1. Are those temps under load or when idling? Can you post a screenshot of HWMonitor when your PC is under load (gaming)?

    While gaming. Can't post right now, i'm not at home. While gaming (mostly World of Warcraft) CPU and GPU doesnt go above 60-70C (~140-160F) and the motherboard has 1 or 2 sensor, i can'T remember. One is around 40 C and one is wrong, says 0 or 1 C.

    I think it should be overheat, but the hardware and the usage is almost the same as it used to be when i bought the PC. Can it be the power supply (450W) or does it help if i update something? Like BIOS, or idk...
  3. It could be the PSU. You wouldn't happen to remember the exact model?
