I knew it! I spoke just a little too soon....
Now the screen goes black repeatedly for only a second or two before coming back perfectly. It seems to do it more frequently if I'm pressing keys ore moving the mouse. Then an error message appeared - "The application or DLL C:\WINDOWS\System32\script.dll is not a valid Windows image. Please check this against your installation diskette"
I don't have an installation diskette!
Actually, I don't even understand!
FIXED! I must be picking up something from you stars!
