Looks reasonably clean. No sign of Spyware or conflicts. I suspect your BSOD's
might be a memory failure showing up due to the software configuration change. Try
running the standalone boot diskette program MemTest86_v3.2 for several hours or over night to see if
it shows up a memory problem. (If its any consolation, I had to buy a DDR
PC3200 512MB CL=2.5 memory module and its on the way, to replace one I bought two
months ago that went bad with a single bit random error. The "local" vendor and manufacture
are no where to be found to honor the warranty, so far.)
