First, computers have inputs to restart the computer. For
example, if enabled - move a mouse and computer will
restart. But if 'mouse movement detected' hardware is not
installed, that 'floating' input can even be triggered by
noise. IOW also disable that 'turn on computer when mouse is
moved' function in the BIOS. Same function is also found on
some computers for modem and for network card. Disable is
located in BIOS.
Demonstrated is one reason why your computer 'mysteriously'
powered on. A long list of other reasons exist.
Second, move on to why your computer does not power up. You
tried to fix the problem rather than first collect facts.
Good diagnostic technicians first collect facts; fixes
problems later. Things such as reseating card, installing
more fans, and swapping parts are common among those
brainwashed by myths. Even a spinning fan tells nothing
useful. The fan can spin and still a power supply is
#1 step: collect facts. The one computer component that can
create strange failures is a power supply. The good
technician, after reviewing Event Logs, Device Manager, and
comprehensive system diagnostics, also uses a 3.5 digit
multimeter to read power supply voltages. Notice I did not
say a motherboard voltage monitor. In two minutes, that meter
reports more useful information than shotgunning (power supply
replacement) would report in 30 minutes.
If you have not yet measured power supply voltages, then
useful numbers were not yet posted here. Why numbers? Notice
that many posted four letter words and other useless
nonsense? You have obtained answers consistent with
information originally posted. You want a useful answer?
Then first get something based in reality - the numbers.
