PC screen goes blank... overheating?

I can't get it to stay on long enough to have a good look now, but I did look through a few days ago. The only relevant section is "PC Health Status" which just shows the core & system temperature, CPU fan speed and PSU voltages. There's definitely no user-changable temperature setting.



Ahh... I did wonder whether the video signal being dropped was what normally appears to happens when the thermal cut-out triggers. So it's more likely to be a motherboard/chipset fault, you reckon...?

I'll set it up outside the case this weekend, unplug everthing non-essential, reset the BIOS and see what happens.

I really appreciate your reply - a mobo fault/short is a more logical explanation than a thermal cutout at 32C!

Cheers! :beer:

Motherboard short more likely to cause a system reboot, chip set fault to cause video loss. Unless it's shorting non stop in which case it's in an endless reboot cycle or something

Personally I'd take it out the case completely and put it on a block of wood and reset the BIOS. Then I'd hook up to onboard VGA and test

If it still goes faulty, then your problem lies with RAM, CPU, M/B or PSU

It didn't work any better outside the case until I attached the PSU from one of my PCs. That seemed to do the trick!

The PSU is a cheap unbranded 250W one so I'll probably replace it with a Corsair CX 400W. Hopefully that'll be powerful enough for any minor upgrades that might be needed...

Cheers all! :T

I'm really confused... it *appears* to be overheating, but 32C (or even 36C) seems really low for the thermal cut-off to kick in. I've just tried running on each stick of RAM individually to rule out any memory problems but the same thing happens.

30C is at HALF the point that the CPU fan would come onto full speed. If it were more than 65 degrees then overheating could be the problem but its not at what it is.

PSU sounds an idea - on cheapo ones, the capacitors dry out.

O/P mentioned it seems to be the PSU, see post before yours. Issue seems sorted now
