Hi, I bought a new comp a few months ago with following specs. Intel Core 2 duo E6600(2.4 Ghz) 2 GB kingston RAM(2*1 GB) MSI P6N SLI Nvidia 8800 GTS 640MB 250GB WD HDD Initially, a few games(NFS:Most wanted and Doom3 at max gaphics) used to crash to the desktop or occasionally give out a BSOD(STOP msg : 7F or 50). I switched the RAM sticks and used them individually and found out that one of them was faulty coz with i didn't have any persistent problems(but i did have the occasional CTD/BSOD but very rarerly) with the other one. I got the faulty stick exchanged and i still experienced the crashes/BSODs with both of the sticks installed. I then just stuck to using the single stick that was working fine and had no problems till a few days ago when I ran DiRT(runs fine at full detail ) and i get a BSOD(PAGE FAULT at NON PAGE AREA). Now most of my other games also crash with a BSOD after a few minutes. I'm guessing the single proper RAM stick also has gone faulty. What i wanted to know was if they were becoming defective coz of a heating problem or if theres a problem with my motherboard. I still haven't run memtest yet, which i will soon. I have attached a dump of the 7F STOP msg. Can anyone throw some light on the issue?
