I'm a computer tech of 12 years, specializing in spyware removal. Today we've had three separate customer computers hit the bench that have all had the same symptom -- they will either not boot into XP Home at all, or if they do, they will give "memory referenced" errors and not open the programs. If you try to boot into "Last Known", same thing. Any of the "safe mode" boot options return a BSOD, STOP 0x000000B4 "The video driver failed to initialize". Also interesting is that the first three memory addresses after the stop error are different, but the fourth is always 0x00050000.
Two of the computers have been Dell systems, one was a custom-built one (not from us). One has onboard video, two had video cards (both nVidia). All three are Intel-based. Two have XP Home, one has XP MCE 2005.
All of them said they were getting popups before it stopped working. Is this a new virus/spyware that's going around and hitting fast? We're not in a big area, and for three to hit the bench with this same problem before noon is pretty unbelievable. I'm still working with getting them up and running, but figured I'd ask if anyone else is seeing this explode all of a sudden over the past few days.
EDIT: Not many points on this because I'm not particularly looking for a solution, just opening a discussion on the topic to see if this is something we should be watching for.
