Or else, when I come back to it after being away several hours, it has shut down, without closing the programs properly.
The screen is black. I think the power is still on, although once I found the power surge bar shut off!
Is is difficult to boot up again, but once I power it up again, it boots without any problems, and runs fine, until it slows down, stops working and fails again.
The ambient temperature is cool, and the hardware diagnostics show no problem. No viruses or malware detected.
It's a stand-alone Dell dimension 8250, Intel, Pent 4CPU 2.66 GHz and the OS is XP Pro 2002, SP3.
I wonder if it is a Power issue. I have shut off standby and hibernate because they used to give me problems.
I don't have a special UPS installed.
Any help appreciated.
