Computer wont log off

[dcoyner]

I am not sure I am in the right place My daughter has a Dell 1545 Inspiron laptop.  It has been having issues off logging off.   I have tried the FN key and it worked a couple of time  now it is stuck on logging off and wont completely log off.  I saw one thing on here that sent me to a micro-soft page, but the problem is I cant get on the computer because it wont log off.

You need to run a diagnostics check on the system you have. When restart hit F12 and boot to diagnostics. Mainly run the check on the memory and hard drive.

If you have windows 7.

Surely you can get on the site if the laptop wont  turn off.  What OS are you using?  Have tried holding the power button down for 5- 10 seconds? If this works re-boot into safe mode and run your anti-virus scan, probably malware and spyware scans too!
