Can you boot into safe mode? (press F8 key as Windows starts) can you then do a system restore back to a time that it worked?

 

[yami007]

he wouldn't do a restore! isn't there any other solution ?

 

[pjmelect]

Although I would be able to fix your computer without doing a restore, I doubt that you or your friend would have the technical knowledge to do so. The lockup may be caused by a virus in which case a system restore would likely not help, which is one of the reasons I asked if you could boot in safe mode

 

[yami007]

so you mean the virus might block the safe-mode and the restore ?

 

[pjmelect]

A virus may delete all restore points. I don't know any viruses that block safe mode.

my friend has the system restore deactivated since he installed windows for the first time...
what should we do?

download ShellExView from here http://www.nirsoft.net/utils/shexview.html

"The ShellExView utility displays the details of shell extensions installed on your computer, and allows you to easily disable and enable each shell extension. "
so when the problem occurs run the software (by a hot key) and try to disable every suspicious shell extension. once you find the culprit locate its directory and delete it.
