Overheating can cause shut downs. Run "HWiNFO32" on it and let us have the temperatures after it has been running a while:

The CPU temperature is of particular interest.

Always pop back and let us know the outcome - thanks

Could be several things... Does it happen very shortly after you power up, or does it need some time before the shut down occurs. Does it do the shut down again after you power up after the first one?

Things to check initialy: ensure all cooling vents are clear, and fans running correctly.

If you're happy going inside the case.... check the cooling fan on the cpu is running and that the cooling fan is still properly adhering to the chip.

There is software that allows you to monitor cpu temperature. Not ever having used it I can't advise which to use, but others here can/will.

Evening Derek, looks like we crossed.. and you are one of those I have in mind re' temperature monitoring utilities...

"For some reason when am using my PC it suddenly turns off for no reason."
Some reason, yes.
No reason, no, you just have not found it yet.
I am of like mind and the first thing I would check for is the temperatures.
Also post more details like: Is it new? Have you made any changes recently? Have you cleaned out dust recently? How? and system specs, especially if custom or customized.

Thanks for the responses guys it's much appreciated. I think the first thing i ned to do is open up the back of the PC and checks the fans are working correctly and there is no dust etc stopping it from working properly as i haven't done that in while. The PC is about 10 years old. I haven't done any modifications to it i brought as standard. Once the PC turns off i can pretty much start it up again straight away but after i did when initially shut down it turn off again after a couple of minutues. Maybe i am running too many programs on it at once and it's over heating maybe. I will download the program you recommend Derek and let you know the temperatures. Again thanks a lot for your imput guys:-)

It "may" also be a possible problem with the power supply. Being ten years old it is possible that one or two main components are ageing. I'm thinking of smoothing capacitors in particular; they can start to leak once volts are applied and the capacitors in effect warm up. As they warm up they leak and thus voltages drop, and the computer will power down... The time it takes to restart allows a slight cooling and resealing of the capacitor andthen the cycle starts again...

It could be overheating or power supply. After verifying that the temps are normal and everything is clean but still happening then check all voltages in HWMonitor or BIOS set up and be sure all voltages are within 5% of their nominal values. If off by more than that or it fluctuates more than a tiny bit when idling then replace the power supply.

just a bit more information when this issue started it was happening when i was playing HD full screen videos on youtube.

HD videos would be stressing the system more than simple things so heat is still an issue as well as a week power supply that is going bad.
Please report back on temps and voltages for us to review for you.
