Power problem?!

My desktop has suddenly decided, when switched on from cold, to switch
itself off after about 2 secs. The time span is so short that I cannot,
apparently, change into any other mode or boot from a floppy.
Can anyone help me out with things to check or something?
TIA

It sounds as if you have a 'major overload' on the PSU (Power Supply Unit)
within your PC and therefore serious.

Unless you feel fairly competent 'under the bonnet' and are able to isolate
the various items of hardware connected to the motherboard in an effort to
locate the problem, you are probably best seeking advice from your local PC
service technician.

Have you added any new items recently, e.g. CD-ROM, hard disk, etc?

Thanks very much Mart. I checked the power supply and one, of the two fans,
has stopped working. I changed back to my old power supply and everything is
back to normal. Will fix the fan tomorrow.

Good to know you've got it running again - and that you're 'handy, under the
bonnet' g

..... I changed back to my old power supply

Ahh! - Somehow, I had suspected that you hadn't told us the whole story

Now Mart be fair - it's my old 300W that I changed to 450W some 18 months
ago!

That doesn't change my suspicions, nor does it negate S-d's Law g

But still pleased you've got it working again. Well done!
