I have major problems with my computer and in desperate need of help. This community looked great on a similar issue and thought I'd share my problem in hopes that someone can help me fix it all up! I run into two BSOD's (sometimes 3, forget what the third one says). Page Fault in Non Paged Area IRQL Not Less Or Equal Please note, I have tried installing Vista many times over and I get the same results each time... This is with a new install of Vista SP2 on my computer. So I have installed Vista 32bit Ultimate onto my desktop, installed ALL updates onto my computer including driver updates which Windows automatically installs. Then at completely random times I get BSOD- "Page Fault in Non Pages Area" and sometimes, IRQL Not Less Or Equal BSOD- however mostly the former. The Page Fault error usually happens more often than not when copying large amount of data onto my hard drive from an external that works perfectly fine with my laptop running vista (however I know it not my hard drive, see explanation in next paragraph). I have run memtest on my RAM- all good. Tried removing separate sticks of RAM and I get the same result with BSOD. I have checked my hard disk for errors and everything is fine there. Even tried using a different hard drive to install vista on- same errors. I am completely stumped! Not to mention extremely frustrated! I know I have minidumps but can not work out an easy way to read them. So I have attached two dumps of 152KB- zipped to attach. It must be an issue with my hardware, but I can't figure out what part... Any help on this would be greatly appreciated, cheers. David Edit: Extra Detail- this BSOD happens at any time. My desktop is currently running fine for 20min and no BSOD, its just sitting here doing nothing- will no doubt BSOD soon without me touching it. EDIT: It just BSOD and I didn't touch a thing- ntfs.sys was mentioned.
