When I run Scandisk, 1st time I got a fatal exception in VXD VWIN32 (05). Rebooted, tried Scandisk again, got KRNL386.exe.
tried to scan for virus, got error starting program, shell32.dll file can't start - tried to shut down got same error again.
Tried defrag, got illegal operation in Explorer shell.dll cause an exception in Explorer.exe
thanks for your help and advice. D
