My PC won't restart

My PC won't restart neither using ctrl-alt-delete, the reset button on
my tower or by start-shutdown-restart. When I try the computer turns
off, but the fans and lights are stil working. Have tried a different
BIOS version but to no help. It's clearly not a software problem. Does
anybody have any ide what may cause this behaviour?

make sure your cards are all seated properly, especially the video card.
check ram also
If reseating the cards and ram fails take the board out and put it on a
piece of cardboard, hookup the power connector and the power to the case
button
if it starts then your board is shorting on the case.

Your symptoms aren't completely clear, so I'll ask a question.

When you plug in the computer, and just flip the switch on the
back of the computer to the ON position, do the fans spin and
the lights work ? (I.e. Without having to touch the switch
on the front of the case ?) If that is the case, perhaps your
case power switch on the front of the computer, is stuck in
the ON position. Try unplugging the case power switch from
the the PANEL header, and see if the motherboard stays off
when you do this test. The case power switch is normally
open, and makes a momentary contact, to start the computer.
With an ohmmeter, it should be open circuit until you press it.

The next thing I would try, is a power supply swap. It could be
there is something wrong with the way PS_ON# works on your
ATX power supply.

HTH,

IF you have windows XP then using ctrl-alt-delete will NOT restart it
anyway...........as ctrl-alt-delete brings up task manager and is not for
restarting.....

Taskmanager is a good way to shutdown if you can't get to the Start button,
etc.

CTRL-ALT-DEL -> Shutdown -> Restart...

Also gives you the option to Hibernate that not on the normal shutdown
screen.
