After a power cut where I live cut out my XP computer, it now crashes on the first BIOS screen with the American Megatrends logo on bootup. It does not respond to anything, except the power off button. However, after having switched it off, if I switch the computer back immediately afterwards or within several minutes of doing so, it boots up through successfully and works perfectly. It only crashes on startup after being switched off for a while. Is it a power issue...?

Thanks in advance

That's an odd one :thumbsup:

The only thing that comes to mind is the BIOS battery. If it is low voltage maybe the CMOS memory is corrupted during a long power off - you boot and it crashes. You reboot and (this is the speculative bit) it resets to defaults.

Depending on the age of your system it may report the battery voltage in the BIOS (most likely press the Del key when you start up and search around for "environment" or "power status" or something like that). Or you could download Everest which will tell you the battery voltage -

I withdrew the CMOS battery, wiped it as it was mildly dirty, and inserted it back in again. This resetted the memory to default, although unfortunately I still suffer the problem.

My intention was for you to buy a NEW battery and insert that. They are available at camera stores if not in your supermarket or newsagents. Its worth a try.

If the computer is 4+ years old the chances are the battery needs replacement.

Nov/Dec last year, so fairly recent.
