When I try to boot Vista with my compaq computer (3.2 GHz) I get the icons loading very
gradually...one by one on the desktop and then after a half minute or so the screen goes
back...windows says computer not shut down properly...and gives choices...safe mode
etc. I have tried these choices but none of them works...and then the screen just goes black.
Might this be a problem caused by defective RAM? What else would cause this problem
and how do I begin trying to solve it?
