I posted this at an Abit forum, but thought I'd give it a try here. I'm getting the dreaded "IRQL_NOT_LESS_OR_EQUAL" error after trying to shut down XP Pro. It only happens once in a while, not very often. There are no other errors at all, and it only happens when I shut down the PC. I'm aware that these stop errors sometimes mean memory is trying to be accessed in an "unauthorized" area, so I turned off caching the video RAM and caching the BIOS, in the BIOS settings. I thought that fixed it, but it came back. So, video caching is off now and it's still happening. I raised the voltage to the Corsair 2 x 256mb TWINX512-3200LL memory, that didn't help.
No new drivers have been installed, or any new hardware. As the PC is right now, it was never doing this, then all of a sudden it started. It's doing this on BIOS versions 12, 15 & 16 for an Abit AN7 mobo. Shutdown will proceed as normal, it goes through the regular screens of "Saving your settings", "Windows is logging you off" and "Windows is shutting down", then BOOM, the blue screen and error message pops up. (I may not have those screen messages above correct verbatim, but I'm sure you know what I mean). All voltage, memory, and CPU settings in the BIOS are default except for Vdimm which is right now 2.9v. CPU is a Barton 3200+, video card is AIW 9800 Pro, PS is an Antec True430, HD is Maxtor 120gb SATA, with Plextor 708 DVD burner and LiteOn LTN-526 CDROM. It's worth pointing out that the mouse is a Logitech MX700 (with combo keyboard), and some of the hits on this issue state that this mouse with older drivers can cause this exact error message. However, there are no mouse drivers installed right now! So, I don't know if that would make a difference or not. I've done a lot of searching on this and can't find anything definitive. I'm hoping someone with an AN7 or NF7, or regardless of motherboard for that matter) has had this, and can say what caused it, or if installing the Logitech drivers will get rid of the error. (In case it may matter, I'm experiencing the infamous two-tone siren beeps intermittently. It is definitely the mobo causing the beeps since EVERYTHING, and I mean EVERYTHING has been substituted, replaced, removed, etc. The beeps only happen once in a while, and only IMMEDIATELY after powering on, and then maybe only one cycle of "low-high" then it proceeds to boot up normally with **no problems**. It never happens while in Windows. All temps, fans, voltages show NORMAL, so, it's not related to them. I thought I fixed the beeps by trying the original release BIOS v12, they went away for more than a day, then they came back. So that didn't fix it). If anyone asks, I don't have the time to install the Logitech drivers and wait and wait for days to see if that fixed it. I have to know now what's causing this. Plus, the customer is not sure which driver/software version he wants to go with just yet and was going to install them himself.
