Well, I've done a full sys scam with norton (the one on their page) and thanks goodness it's everything is allright there. I'll defrag today later on.... don't really think it's heat 'cause the rest of the sys it's allright.... So maybe it's the damm size of my files, like too many of them, I've been colecting files for years now... so, I'm deleting stuff, just the bump files gave me about 2gigs of space.... anyhow I think poser can take that many files.... hard decision now, what to delete what to keep? thanks all you guys, it has been great help and I really apreciate that vince
