Be sure RAM memory is still ok. Memory gone sour can cause a plethora of erratic behavior making one look allover the place.

Case you have 2 RAM modules, remove 1 and see what happens. If its still there, swap it. If still the same, it's less likely it's RAM.

If either one solves the problem, the other RAM module has "lost it".
