A few weeks ago I started getting this BSOD but only when I wasnt at my computer. Sometimes it also gave me a message about ntfs.sys. My work around for this problem was to run a macro when I wasnt at the computer and this kept it from rebooting. Then a few days ago it started rebooting with IRQ_NOT_LESS_OR_EQUAL or page fault in non paged area when I was using it. Obviously this was a lot more inconvienent. I read every forum I could find and found no solution to the problem until a couple of days ago I was reading this forum and someone suggested checking the page file, I did and sure enough my page file was too small. I increased my page file so that the min and max were both 4000 and things were running smoothly again.... for about 3 days then this morning I was working in photoshop and I blue screened with IRQL_NOT_LESS_OR_EQUAL and I'm back to where I started again, if I leave my computer idle it reboots and I cant find any way to stop it, I dont know why changing my page file size would have fixed it then a few days later stopped working.
