BAD_POOL_CALLER and agp440.sys
Hello, I have a problem. I am trying to fix a friend's Laptop. It was randomly shutting down and giving a Blue Screen with a BAD_POOL_CALLER error and the stop message "0xc2 (0x00000043, 0xC4AD4000 [this one changes] , 0x00000000,0x00000000)."
Now I can't even get into Windows before it give me that error and tries to restart. When I try to get in in safe mode, the computer hangs at "agp440.sys" and gives me the blue screen.
I've run MemTest86 to test the memory and it ran 12 tests and didn't show any sign of stopping or of errors, so I cut it off after 3 hours and assumed that was not the problem.
I tried to run the windows XP repair deal off the install cd, but it blue screened me right after I selected which drive I wanted to repair.
I've searched all over different forums and help sites and there seems to be a lot of people having similar problems, but no solutions anywhere. Threads either end abruptly or the person with the problem buys a new computer. Does anyone have an actual solution that they can post so that myself and the apparently large number of folks with this problem can fix their computers.
I can boot into DOS with a cd so I was wondering if I could copy the agp440.sys file off of my computer and put it on his? Would this work, destroy the computer or am I in the wrong place entirely with this agp440.sys nonsense?
If all else fails, is there a program out there that can burn cds in DOS so that I can get his important files off of there before clearing the hard drive and reinstalling windows? (will that even work?)
