Hi People....
This is my first time on this web site so excuse me if I made any mistakes.
I have a Fujitsu Scenic D with Windows 2000 installed on it. The problem is that when the computer is Started up, it goes through the Boot up then stops. A blue screen appears with white writing telling me that if this message appears to switch off and restart the computer.... it also says to check for virus's.... I restart the computer but the same keeps happening.
Would I need to remove windows 2000 from the Hard Drive then re-install again.
