    Hello

    Should this be in Windows Forums??

    My computer (details below) started to shut itself down unexpectedly. At first I thought it was overheating, but it persisted in crashing and wouldn't reboot unless I isolated it from the power supply. The periods between bootups and crashes went from 45 minutes down to a few minutes. I decided to do a reformat of my hard drive. After I had re-installed Windows 98, I shut down and went to bed.

    The next day, I noticed on the bootup screen that my processor speed had reduced from a 600 MHZ Via Cyrix III to a Via Samuel MMX 400MHZ. Why did this happen. Is it an example of the manufacturer overclocking? Or is there some other reason why the speed reduced and the processor changed?

    Additionally, the time between bootup and crash is now anything from between a few minutes down to a few seconds. Sometimes it doesn't get as far as loading Windows. Every diagnostic program I ran before my problem showed that my computer was pretty crap compared to others. So another question is: has anyone else (particularly UK) had similar problems with a similar computer to mine?

    I don't know if all this is relevant information.

    Kind Regards

    :D Jrob,

    This sounds like a power supply going bad. It could also possibly be the CMOS battery dying. I would try a new power supply first.

    Hello kilowatt1

    Sorry for the 3 week delay. But to tidy this up: you were right. It was the power supply. I sent it for repair and have just received it back with a note saying they had replaced the PSU (3 weeks for a PSU!!). Everything seems OK now. Famous last words......

    Thanks for your original reply.

    Kind Regards

    John
