more detail would help us trouble shoot your problem, such as ur notebook brand and specs.. your definition of F8 is when you boot up your windows?

Please use sentences. Trying to read something like this is a pain.

Anyway, I would test your memory and hard disk with the Ultimate Boot CD.

as stated it is an acer extensa 5220, and the option of hitting f8 to get other start up problems does nothing

You ran the tests and they were all green? Just because they work for a bit in another computer doesn't meant they're good parts.
