Often on BSODs under Win 7 x64, but I doubt that this file causes the bluescreen...

I believe FLTMRG.EXE is Fault Manager. About 2-5 minutes before my BSOD I see AdAware fault. First once and 3 times in sucession. Always I get the BSOD implicating fltmgr.exe but I think it's really AdAware. I stop AdAware and haven't gotten the BSOD for weeks now.

Pretty sure it is a necessary Windows file, however it is the #1 cause of BSoD's on my W7 Home Premium (Running on an ASUS G74Sx).

There are 2 different versions on my computer, and the newer one seems to be a problem with Windows XP SP3. The computer will not run with SP3 installed.

XP SP2 worked fine but the SP3 update would not load after updating the system. Booting in Diagnostics mode, the BSOD reported that FLTMGR.SYS was crashing the system.
