Hello everyone, long time fan, first time poster, I have been encountering a system error for awhile event 1003 category 102, the BSOD says IRQL less than or equal to and it happens on random occasions, there is nothing in particular that I am doing when it Shuts down, playing games, surfing the internet, rearranging files, etc. Also 2 Dcom Errors, both event 10016, and 2 Service Control Manager Errors, event 7000 and 7009, always occur before the System Error and a warning on my TCIP, event 4226, occurs after the System Error. I was able to Diagnose my minidump and it looks like the problem is the Ntfs.sys file, however I am not sure and if it is I do not know how to fix it. My computer is running on windows xp 64-bit professional. I also updated all my drivers and none of them have warnings. Any help in fixing this would be much appreciated. Here is my minidump file for the System Error.

From Auhma.org: 0x00000024: NTFS_FILE_SYSTEM

A problem occurred within NTFS.SYS, the driver file that allows the system to read and write to NTFS file system drives. There may be a physical problem with the disk, or an Interrupt Request Packet (IRP) may be corrupted. Other common causes include heavy hard drive fragmentation, heavy file I/O, problems with some types of drive-mirroring software, or some antivirus softwar.

1. Run ChkDsk or ScanDisk as a first step.

2. Run a full harddrive diagnostics by utilizing the free utility from your harddrive manufacturer.

First off I'd like to thank you for taking the time to reply to my plight. Well I was able to run chkdsk which found a few errors, so I ran a full chkdsk at reboot, which I suppose might have fixed the problems, because when I ran WD diagnotics to check my hard drive it passed, although I had not run the diagnotics before chkdsk so I have nothing to compare it to. I think I will just have to let time show whether its repaired or not, because it was never a constant problem it would intermittently just shut down and flash the BSOD. Nevertheless thanks for the advice, I will probably end up reporting back to techspot when further complications arise.
