IRQ_NOT_LESS_OR _EQUAL Blue Screen STOP Error upon bootup. Tried every suggestion I could find including turning off memory cache in bios, and disabling all hardware devices that I could. Tired to boot to safemode in order to check for conflicts, Viruses, etc but got 'XP cannot use safe mode' error.
Installed another instance of Xp Pro, patched it, and installed symantec AV, Spware Dr, and scanned entire disk. AV found nothing, Spyware DR found 3 tracking cookies, but no real threats. Everything I read pointed to hardware corruption, conflict, bad memory or other hardware, (Fan, Mother board) Bios flash, or possible virus, but it seems to be OS related as I can install fresh instance and am OK.
and many others and nothing referes to OS except to suggest there may be a virus. Now I can access all folders on C:\ except my Document & Settings profile (no permissions) and I'd have to reinstall all apps.
Question can I still recover the other install? Identify problem/corrupt system files, etc from this point?
