I've just done a System Recovery on an e-machine using their recovery disks and I have a problem which was there before I did this. When I go to Shut Down everything does so as normal except for the fan on the power supply, which just keeps whirring, and the only way to switch the pc off is at the mains. This happens with the old power supply and even a brand new one I've tried.
if pc you may have a pb with power supply heating up...suggest swap for another one from a friend pc... and try. If not working, then you may need to upgrade the bios... but don't do it without supervised expert advice. If pc under warranty, then avoid doing this trick and back to manufacturer/reseller...pronto
if laptop from time to time faster may still run coz of the bios not reinstated properly or protection for overhearing issue... think to avoid "hot" places
This is with a desktop, and happens even with a new power supply. The graphics drivers are loaded and (I assume) OK since I did a Recovery to factory default using the supplied Recovery discs that came with the machine.
I've tried removing the internal battery for a few minues and replacing it. I've loaded the BIOS defaults. I've removed the modem, graphics card and memory but I still get the same problem.
When I don't connect the floppy and switch off, only the psu fan keeps spinning. If I do connect the floppy and switch off, the keyboard lights flash on and off very rapidly and the floppy drive spins as if trying to accessing a floppy in there.
The only conclusion I can come to is some fault on the motherboard, unless someone else knows different?
