I think, that the Ram-card is not very well installed in the slice.
Take care as first that you are anti static, than must you check out or the Ram-card is correct installed.
Check also the ide cable. When you opened the case, than you will see a red cable from the Mobo to the Hard disk, when the red cable is not stable, than get you trouble too, just like what you did said.
