    Hi,

    I am using an HP e-pc machine (which uses a small form factor motherboard) and recently it simply switches off with no warning what so ever. Seems to happen more often when running intense applications.

    I'm unable to reboot it using the power switch, I have to manually unplug the cable, and plug it back in at the back to get it to turn on. It'll switch off in dos (in the bios menu) and in windows, no bsod or anything similar.

    I thought it was a heat issue, however after ensuring the heatsink+fan were properly set, then leaving the case open and hainvg a second fan blow at it, it still turns itself off.

    This is a pentium III machine, and unfortunately there are no temperature gauges in the bios, and I don't everest doesn't recognise any either. The power supply is an external one, similar to a laptop power supply design, using a 19v/3.16A.

    I am not normally able to keep it running for over an hour.

    Thanks in advance,

    Louis.

    Since you've determined its not a heating issue, it could be a power supply issue. Do you have another power supply you could test?
