Hi guys, I've been getting a bsod systematically on startup for about a week on my laptop: receive the stop error 0xD1 DRIVER_IRQL_NOT_LESS_OR_EQUAL I'm not sure what info could be helpful for figuring this one out so here's all i can think of: The computer, a rather ancient HP Compaq nc8000 running: XP Professional, Intel Pentium M 1600HZ, ATI Radeon Mobility 9600 series, 512 RAM - can't find the make I haven't added any hardware recently. I would have tried wiping it but it's got some files on I need, and I can't get them off - receive I/O errors when trying to copy to a USB drive, FTPing to my web host won't work, can't send email attachments, and up until today the CD drive wasn't working. I have ran a chkdsk, a defrag, have restored the system several times to a previous date, have tried Last Known Good Configuration to no avail. I managed to download a Microsoft Automated Troubleshooting Services fix for that and lo' and behold it worked (at least it's reading, I havn't tried writing) so I managed to load the HP Driver Recovery CD. That appeared to install all but one driver okay (printer driver failed) but didn't make the BSODs go away. I have seen on other threads that the problem may be faulty RAM, unfortunately because of the above problems I can't run memtest, although I've never had any RAM problems before and havn't added any recently. I have tried running a few antivirus/spyware scans:- AVG, Malwarebytes, Spybot S&D, the latter found a couple of trojans in the registry, one malware entry and some cookies. Cleaned them but that didn't fix it. I should mention in case it's of any signicance that Safe Mode doesn't load properly, it runs up until Windows\System32\Drivers\agp440.sys and then hangs, then the message "Press ESC to cancel loading SPTD.sys" flashes momentarily at the bottom of the screen. I can load Safe Mode if I tap esc at that point. Previous to these errors the laptop was running more or less fine - a few problems with the screen flickering to black (or very dark) when I tilted the screen back or forth - always returning to normal when I rebooted. I figured that it was a loose connection due to it being quite an old machine. It was a second hand and sound never worked on it since I've had it, I assumed this was due to missing hardware but I never looked into it as it didn't bother me. It does bleep when I get alert boxes but that's it. I have also tried dusting the outside vents but I'm reluctant to venture inside the machine as I'm a bit of a greenhorn and don't want to make things any worse. I would try to repair using the Windows Install CDs but I don't have them at hand. I know a replacement is probably overdue but I can't afford to replace it right now. Any help you could give would be a real help to me, thanks for taking your time on this one. Ps. I have attached my 5 latest minidumps and a hijackthis log as was recommend in some other posts. I hope I have provided them in the correct formats. Once again, thanks for any help.
