Hi everyone ,something bothering me for a long time now need some help.My PC just started behaving rather strangely over the past 2 weeks,it turns itself down automatically without warning.After reboot it comes up for half a minute and then goes off again.When I tun it on again after say an hour it works for around 20-25 minutes and goes off again.

My Pc is 5-6 yrs OLD.It could be a heat related issue but barring that if its a Hardware issue then which one is most likely???(also it stopped working something before was not getting powered on by pressing the power button later on I found out that the CMOS battery was faulty,PC started working after replacing the same )

Time to clean out those fans and heatsinks. It could be a PSU issue but it sounds more like its just heat build up caused by dirt.

The CMOS battery typically will not stop the PC from booting

it WILL complain about date-time being wrong (press F2 to continue, etc).

As Kenone mentioned, clean out the dust, and make sure all fans are spinning.

From a pure electronic troubleshooting standpoint, it might be a case of faulty capacitors on the motherboard. Do a google search on Badcaps for more info.

My guess would be that the mobo is bad, not the PSU.
