ok i cleaned out my computer. Windows loaded up without a hitch, and im now posting from my afflicted pc once again. opening up speed fan everything is running much cooler... although i found it odd that my computer is running 50% of the ram at a standstill. So looking further into speed fan, its telling me that i only have 2gigs of ram, when my pc has 4 gigs. So...im guessing i just straight up lost a 2gig stick...what the heck??? where do i go from here. Did this cause all my problems to begin with?
