Windows 7 does not shut down

[doulton]

Hi, I run a windows 7,IE 8 64 bit PC.

Ocassionaly,when I try to \"SHUT DOWN\" it will not do so . The screen says \"SHUTTING DOWN\" but never does.even after several hours wait . I have to close down on power supply. I have run full system Norton, have run Register clean and Disc clean and defrag programs . It has just done this malfuncion again .

Any ideas would be welcome. Thank You.

Hello,

Normally, it’s because certain processes in the background with special authorities cannot be ended by System when Windows Shut Down, which accordingly causes hung-up of the system.

Generally, it’s a problem brought by viruses, Trojans, driver module bugs of anti-virus software, or there’s something wrong with hardware drivers.

Please firstly confirm your PC is not affected with viruses or Trojans. 

Then please try uninstall the anti-virus software you are using and update certain hardware drivers.

After you have fixed the problem, you can re-install your anti-virus software.
