Computer doesnt shut up

[gamerxx13]

Okay, when I got to shut down for windows xp my computer goes to the shut down screen. Then the moniter goes out like no signal from the computer but the computer is still running. What is going on here, is this because of a virus or something. It never did this before.

Usually a problem with ACPI - maybe the mobo, maybe the power supply, maybe the ACPI driver in Windows, maybe a BIOS issue. It's also possible it's a software program hanging on shutdown. A virus is possible but unlikely.

Try some experiments to nail it down:

- Do you have another PSU you can temporarily connect just to see if it does the same thing? No need to swap out the PSU, just temporarily swap the connections.

- Try booting into safe mode and then shut down Windows and see if it does a proper shutdown. If it does, then it's likely an ACPI driver issue.

- If you think it maybe a software or driver issue you can use System Restore to go back to a restore point before the problem started happening (for technical reasons too complicated to discuss here, go back AT LEAST ONE WEEK before the problem started).

Hope this helps...

Boot in safe mode. Do a shutdown. Can you now shut down normally? If so, you've added something to your system recently that is preventing the shutdown from taking place. A quick place to check is filter drivers, but before we get into that please tell us what happens in a safe mode shutdown.
