Hello there, apologies if this has been covered but the Search function has been disabled.
As of the past two days, the main home PC has been sporadically turning itself off, especially during games. I figured this was down to over-heating of the CPU so I removed the side of the tower and made double sure by giving the CPU fan and the heatsink a good dusting down. I also checked the system temperature and noted that it ran anywhere from 24degreesC to 45degreesC.
What further re-inforced my belief that this was a problem relating only to cooling was that immediately after it switched itself off, I would press the power button only to be greeted by a brief few seconds of boot-up before it once more switched off immediately. If I gave the PC a minute or so, it would boot-up as per usual and thus I suspected it was all down to cooling.
However, in the past thirty minutes the PC has suddenly died. It performed the usual of switching itself off suddenly. Ok, so I waited a minute or so. This time however, the power stays on and the monitor gives me the message "No Input Signal Detected. Check Connection or Input Source". Bugger, now the monitor won't pick up the PC's signal. The PC keeps on whirring and I see no action on the screen. It won't even respond to a cold restart by holding down the power button.
Now I suspect it's a faulty PSU and/or CPU.
Can someone please enlighten me?
