For a very long time I have been having trouble with my computer and/or browser shutting down. This problem is getting very frequent, sometimes it shuts down again right after rebooting over and over again or freezes, other times it is fine for hours. (I noticed it doesn't shut down in safe mode). Even desktop recovery doesn't work stating "object doesn't support this action). Just recently, when I click on my "My Documents" icon on the desktop I get this message: "Internet Explorer" This page has an uspecified potential security risk". Frequently the browser (both IE and Firefox) crash, more frequently I get the BSOD, but never the same one. I have gotten these messages and maybe more I can't remember: IRQL not less or equal, Page fault in non paged area, bad pool caller, driver corrupted MMpool, A driver has corrupted the memory management system PTES, PFN list corrupt, driver IRQL not less or equal, windows corrupt file exception processing message c0000102 Paramenters 75b6bf7c 75b6bf7c 75b6bf7c 75b6bf7c. I have Windows XP Professional Version 2002, Service Pack 3, 32-bit, AMD Athlon (tm) XP 3000+, 2.17 GHz, 512 MB of RAM, with Avast antivirus and Spybot. I have gone through the procedure on the malware thread and run the SuperAntispyware which found nothing.
