Hi there, Since this morning I have not been able to log in to my comp (apart from in safe mode) due to the BSOD occuring momentariyl right after the XP splash page, and then it just goes to a black screen. I have not installed any new hardware since yesterday and the only thing I can think of that has changed is some Adobe software that updated itself last night. The BSOD has happened to me before but I ignored it and it didn't seem to come back that often. However now, it has rendered my comp semi-useless and I would really appreciate any help. So far I have: cleaned all dust, run a virus scan, disabled all start up programs (that aren't microsoft corporation), done run "chkdsk /r /f", tried booting with no USB hardware in, disabled my network adapter (which has recently been giving me some trouble), restored system to most recent point, restored system to least recent point ...and still come up with nothing. It comes up with the usual error "Driver_IRQL_Not_Less_Or_Equal" and gives this code: 0x000000D1 (0xC4F36FA3, 0x00000002, 0x00000000, 0x8630AC88) It also mentions this in event viewer: The following boot-start or system-start driver(s) failed to load: AFD AvgLdx86 AvgMfx86 AvgTdiX Fips IPSec MRxSmb NetBIOS NetBT Processor RasAcd Rdbss SASDIFSV SASKUTIL Tcpip Tcpip6 XPROTECTOR I'll attatch one of the many mini-dump files I have as well. Many, many thanks in advance... I really hope I don't have to repair/reformat my OS because I've lost the disk. :blackeye: P.s. In my eventvwr, it has a lot of (!) warnings saying something about the TCP/IP Protocol, could the problem be related?
