Hi! I haven't ever really had much trouble with BSODs before, so I'm pretty confused as to what to do with my desktop. As of this past Friday, I was using my desktop completely fine; no issues with anything at all. After moving over the weekend, I opened my tower up, cleaned the air filter and air dusted the interior, and then hooked up the computer and got pretty much nothing. Sometimes I can boot the computer up, sometimes it fails before anything shows up on the screen. Sometimes I can get to the login screen, sometimes I can actually start some programs up. I've noticed that if I start up a game - one I've never had trouble with in the past - it seems to load a bit slowly, and the refreshing of the graphics is noticeably obvious. I ran chkdsk /f /r, but it doesn't seem to have fixed the problem; I also got UBCD, but I don't know what exactly is wrong with my computer, or how to go about using UBCD to fix things. The error messages I pull from Event Viewer and from this crashdump reader don't seem to agree, but ...but then again I don't even know what I should be looking for. Help!
