If there's a case for leaving your PC switched on all the time - this is it!!!
Powered-up this morning to find that the Dell PC was crashing when trying to load 'explorer.exe' - probably the most important file under XP. It even does it in safe-mode!!!
To compound things, system restore doesn't seem to load and nor does any other program if I attempt to run it...
Bugger! Dell are M-F support..so it's a frantic search round the Internet to try and solve it today.
