Well I'm kind of desperate so I guess I'll give a try and ask about this problem here, several heads thinking is always better than one. Recently my Windows XP crashed and I can't login. It happened after my system got affected by trojan which was successfully cleaned but after that the crashing began. System stops at logon, sometimes I get blue screen of death, sometimes it stops at "Loading your personal settings" and in a few rare instances (like one in 20 tries) it manages to log on and even works for some time. The full description of error in blue screen goes: PAGE_FAULT_IN_NONPAGED_AREA STOP: 0X00000050, 0XD0381122, 0X000000001, 0XAC3C492B, 0X0000000000 By reading around the forum I know it's something memory related or faulty drivers but since the windows were working perfectly before the trojan deletion and no new hardware was installed in longer time I can only surmise there is a fault with one of device drivers - either it got deleted or corrupted. Any way I could find out which device driver or system file it is? If it is any help or indication - booting in Safe mode works perfectly, although it halts a bit on loading d347bus.sys Any ideas and any sort of help would be most appreciated! Thanks.
