Hi. I am going steadily insane due to BSOD. When I start my computer (which is old) I get a BSOD after a few seconds of the desktop appearing. Usually just before windows live messenger is about to load up. I have discovered that If I log onto the guest account and then switch user to my account it solves it. I dont know if that is significant in any way. The BSOD message always includes an sp**.sys file. These files are from the last few BSODS. It does it every time I startup. spvc.sys spfk.sys spfp.sys spci.sys spmj.sys splz.sys spva.sys my Bitdefender installation also stops responding on occasion which also seems to slow down my computer while it restarts.. Could this be a virus? I have a very limited knowledge about technical stuff.
