|Hi Vickie, I would forget the bios and concentrate on starting the pc first.|
The psu fan not operating is suspicious.
With the pc disconnected from the mains, I would start by opening it up and blowing out any muck with a hairdryer set to cold and maximum blast. Use a long thin soft brush to assist.
Especially blow through the psu. Probably I would remove and open the psu itself before blowing through.
The above is worth a try. If it works, you do not have to find another psu for testing.
Please advise back on progress.
Good Luck - Keep us posted.
