I recently bought a new computer.. HP Athlon 64 x2 4200+ 2 GB RAM (1 gb per stick) 300GB Seagate HD Nvidia GeForce 6150 LE with most recent driver from Nvidia website. Running Windows Media Center Version 2002 SP 2 This computer was working great for about one month... recently it has been randomly crashing and it has been happening very frequently now. The first one I noticed said "Problem caused by file NTFS.SYS PAGE_FAULT_IN_NONPAGED_AREA. The second error was a stop 0x00000050 The third was Stop: 0x0000004E I don't know how to read minidumps yet but I have attached mine if someone could please take a look and let me know what to look into that would be great. I'm hoping to get this fixed ASAP but if it is hardware issues then I need to send this back within the next 30 days. Note: I updated the video driver after one crash when i read on these forums that it could possibly be the problem. My crashes have all different error messages so far so this has not fixed the problems. Also I recently did scandisk and defragment and it has not helped.. defrag almost seemed to make this worse. Thanks for the help! I truly appreciate this.
