Today my PC has shutdown twice randomly. We’re talking going off just as if there’d been a power cut.
When booting back up again, Windows doesn’t say anything about shutting down badly.
I’m not sure it’s heat because checking BIOS at the boot up, temps were 27C and 25C.
And Speedfan shows this:
HDTune shows no errors on either of the the hard drives.
Using HWMonitor gives this
which looks far better to be honest!
The voltages show fine in BIOS as well.
If it was the PSU, I’d expect it to shutdown when it draws more power, ie I start a game or something but this went the first time whilst I was backing up a Steam game to USB and the second time when I was running a defrag.
I’ve already got a drive on it’s way to replace the IDE drive there (which Steam is installed on) and was the drive being defragged (should be here Monday - eBuyer made damn sure I got it on the 5th working day )
I would have said PSU, but my second choice would be memory. I’d run MEMTEST86 on it overnight to be certain that isn’t the problem. Also, take a look at the motherboard and make sure none of the aluminum electrolytic caps are starting to “popcorn”.
Overnight isn’t an option (it’s in my bedroom and I need to sleep!) but I’ll put a Memtest on during the week whilst at work. I’ll check the board when my hard drive arrives.
