Hi. My PC has developed a habit of turning itself off and not allowing me to start it up again again until some considerable time later. When it refuses to restart something in the tower emits a faint siren sound. I am suspicious of the PSU that i received when I purchased the case, its label says its a Mega Power CTX-450WCE but I cannot find any reference to this model. None of the components appear to be damaged. Can you help me solve this very annoying problem.

Can you run the PC with Everest minimized on sensor and check it every 5 minutes to see if any of the temperatures rise quickly

If you also click computer then summary in Everest you can see most of the installed components

Whenever you run the PC, if the temps don't rise too much it isn't that

You can click start then run, type chkdsk /f /r then press enter, type Y to confirm for next boot, press enter then reboot, it will check the drive but take an hour so only run it when you do not need the PC for a while

Noticed my PSU was installed with the vent side closest to a side panel a few days ago and turned it round. Initially there was no noticeable improvement (took a second or two longer for the siren to kick in), then it started running longer but still wouldn't restart. Got it to run the check disk though, which it is still doing, does this info help at all? Also, what is this chkdsk command about?

Havn't been able to do any of the stuff you said as I havn't been able to get my PC to start up since I last posted. Its started making a sort of faint whistling sound when the PSU is switched on, and the LCD display has started flickering between different brightnesses.
