Hey everyone...Well this has just been recently happening to my desktop pc. I built it like a month ago brand new parts and now its doing Physical Memory dumps and shutting down...I don't know what the problem could be. It used to happen like every hour, but now its every few hours which is better but still sux if ur doing something. I'm tryin to do updates to see if that is the problem. I almost get the same error(s) everytime. its either this PAGE_FAULT_IN_NONPAGED_AREA or its DRIVER_IRQL_NOT_LESS_OR_EQUAL . I took all the cards out that wasn't necessary, and i disabled the onboard nic. and it started to run better. Then in about an 2-3 hours it shut down again so i was like hmm ok...so i unplugged my extra hard drive, my 2 cd roms and floppy and let it run. It ran for a little longer, but i don't know if that is because im not doing as much on it or not. I have also reinstalled windows...When the problem first started i was running Windows XP Pro, and i reformated and put Windows 2000 Pro...That seemed to help as well, but I don't know what the problem could be..Anyone have any ideas, or anyone know any diagnostic tools i could get to figure the problem out?
