Thanks for your services.
I just got a Blue Screen Of Death on a 1 year old Dell Inspiron 530, running XP, SP2. Never had a problem before. Tonight, my wife started Left 4 Dead 2 and it went to blue screen and rebooted. I saw another thread here very similar (http://www.daniweb.com/forums/thread250395.html) and read the suggested link to Microsoft but it is really not any help since I cannot boot to windows and I am not using SP1.
I cannot boot to any option (safe mode, safe mode command prompt, last known good, etc). Always get the same BSOD. I disabled auto-reboot and do not see any specific cause. There is no program identified. The message just starts at the top with page_fault_in_nonpaged_area and at the end, it says
Stop: 0x00000050 (0xEC6B738D, 0x00000000, 0x8AEA508C, 0x00000002)
I ran the Dell utilities for memory test and system test and no problems were found.
I unplugged the network and printer. I only have USB mouse and keyboard (USB are the only ports on the system).
I booted to the XP CD and ran chkdsk /R and no problems were found.
I check the beep.sys just in case and it is the same size and date as another on a working system. No virus here.
I use Kaspersky and it updates its virus list daily. I occasionally run spybot and adaware, but not recently. I do not have auto-update enabled for XP.
I am contemplating doing a manual system restore from the recovery console. I am contemplating trying to disable the video driver from the recovery console but since I cannot even boot to safe mode command console, I doubt that will help.
Since the problem started when we ran an OpenGL game, I figure it might be graphics-related. But we have played that game several times before with no problems. Plus that Microsoft link you sent for the other thread suggested disabling the video driver.
Of course, I am ultimately thinking about doing a system repair since it does not seem to be hardware-related. But as you said in your repair thread; I need to figure out what is causing the problem before I do a system repair.
