My computer has started to randomly get the blue screen of death. Sometimes I get it a second after windows loads. Sometimes I get it about 5-10 minutes after windows loads. Sometimes I can run windows for about 1-2 hours before I get it. Also, upon restarting my computer after getting this message, my computer sometimes freezes up after. I was running service pack 3 with all the updates. I brought my computer back to factory settings hoping to fix this issue. It worked fine for a day then it started up all over again. (I used F10 and not a restore disk) Here are the messages I generally get: Driver IRQL Not Less Or Equal Page Fault In Non Pages Area Alternates between these two errors. I read former posts about these problems on these boards and heard it could be a problem with my RAM? I downloaded Memory Tests and it didn't say I had any problems. Also, my computer runs fine on SAFE MODE with networking. HP Pavilion a640n Windows XP AMD Athlon(tm) 64 processor 3400+ 2.19 ghz 512 mb ram 160gig ultra dma hard drive Samsung SP1604n If anyone can help me it would be appreciated =) UPDATE: I finally found out what was causing my blue screen of death errors so I will post what my problem was for anyone else that might be experiencing the same errors: * Right click on my computer * Click on properties * Click on hardware * Click on device manager Disable all drivers except for the video adapter and network card Restart computer and see if windows boots normaly Mine did. Enable a driver one by one while restarting the computer to find out which driver is giving you the problem. The driver that was giving me the problem was my processor driver: AMD Athlon(TM) 64 Processor 3400+ Once I disabled this driver Windows would boot normally without any problems. So here is my new question: What are the side affects of having this driver disabled???
