My PC locked up at pre-boot

[Guest a]

Hi

I have posted this problem about one week ago.

The problem was fixed by no reason for a while, and now it comes back again.

 

Problem description

My PC is locked up at pre-POST stage.

The keyboard light is flashed once. I have replaced the battery.

99% of the time, no monitor signal received.

 

1% of the time, the monitor receives signal and it shows that the boot

sequence halts at "Initialize Plug and Play devices"

 

So, how should I narrow down the troubleshooting?

 

Thanks

Standard caveat: Testing hardware failures often involves swapping out

suspected parts with known-good parts. If you can't do the testing

yourself and/or are uncomfortable opening your computer, take the

machine to a professional computer repair shop (not your local

equivalent of BigStoreUSA). Have all your data backed up before you take

the machine into a shop.
