Ryan1,
This support forum is intended to support users who are experiencing difficulty with WGA Validations/Notifications on Windows Vista. Your issue does not appear to fall into that category so it is off topic.
May I suggest checking your RAM with the diagnostic program at the following page: http://oca.microsoft.com/en/windiag.asp?
You will be more likely to get help with your problem at online hardware forums such as www.tomshardware.com, or at a reputable neighborhood computer repair shop.
Good Luck!
