While browsing in normal mode I suddenly got the blue screen of death with the following information: DRIVER_IRQL_NOT_LESS_OR_EQUAL Technical Information: 0x000000D1(0x73656CD7, 0x00000002, 0x00000000, 0xF8219678) The system would then not boot in normal mode and when I tried booting in safe mode, it hung at the following command: multidisk(0)disk(0)rdisk(0)partition(1)\WINDOWS\SYSTEM32\DRIVERS\agp440.sys I then boot it from a bootable XP cd for repair and ran the chkdsk command on C:\windows but still it did not boot properly. I tried all options for booting including the last known good config and debugging mode but could not boot. Could anyone please advise how can I boot properly without formatting the system? Thanks for any help

Find a list of STOP MESSAGES(BSOD) here: http://aumha.org/win5/kbestop.htm Then find and click D1 that is on the right side.

Thanks for replying Chuck. The website refers to an update installation to overcome DRIVER_IRQL_NOT_LESS_OR_EQUAL error but in the first place how do I boot into safe mode or normal mode as for now I can't even get windows booted.

Run a Windows Repair (not the Recovery Console.) "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

I forgot to tell that when the BSOD appeared initially, I was able to reboot in normal mode and then I enabled the chkdsk option on my C:\ drive after which the system re-booted but it started giving the DRIVER IRQL mssg from then onwards and I couldn't boot into any mode. I've run windows repair from a bootable cd (not using the console recovery option) but upon re-boot it again displays the BSOD and I can't go any further. Could the chkdsk enable option be disabled from the command prompt or anything fixed in the boot.ini to fix this ? Any other suggestions......thanks again!

The two most common causes are bad RAM or a corrupt driver.

How do we fix it if that's a corrupt driver?
