dead pc

i've got a dead pc! please help...
it's started by the date and time resetting to jan 2001 23:00hrs and this knock the antivirus software off (mcafee) which i thought may have let viruses in so i ran a scan on my mcafee but found nothing. then, just to make sure i downloaded avg and this found a few things (can't remember the names) which i healed but then i got a dialog box saying system file were missing and i needed to reinstall them then got a dreaded blue screen and then it would only start in safe mode.

i was about to back up my files in safe mode when it just shut down with a blinking green LED on the front panel as though it was in standby mode or something but would not come back on the mouse or keyboard. i left it for about 1hr but it was still blinking so i tried turning it off at the wall socket and it hasn't turned on since
there is power to the mobo as the ethernet socket is lit at the rear but it does nothing else!!

i looked on some forums and it suggested changing the mobo battery for the date and time problem and i have a multimeter at the ready to test the 3 voltages to the mobo.

any other suggestions would be very welcome before the pc follow the laptop through the same window (laptop ...different story!!) :#
thanks for looking.......seymx

I agree about the comment re Battery on mobo. Also, if or when you get it going again, make sure that you only have one Anti-virus - I would keep AVG get rid of McAfee.

It could also be a dead or dying PSU, the light on the rear socket could still be on even with a dud PSU.

Your running an old computer 2001 the computer will default to when it was made,do a full reinstall of the OS you will require your recovery disk that came with the computer.

To be fair, changing the battery sounds like the right thing to do.

I would suggest, try a new mobo battery, only a quid or so. Then if still no different, another PSU.

If you can borrow an ATX PSU from someone I would try that first to see if you can at least power up the system.

Also, as others have stated previously, it does look like the mobo battery needs to be replaced.
