Since the Sony didn't have any important data or programs on it, I suggested restoring to factory defaults. Half way through the reset process, it crash dumped again. I tried restoring to factory settings 3 more times. Same result each time.
I used the Sony Diagnostic Tools to check all hardware (this ran for about 3 hours). It reported that there were no hardware errors.
The BSOD is only visible for a short period, too short to write down the error reports, but I can tell they are different each time.
I used the linux disti Slitaz to copy My Documents onto an external hard drive and it ran absolutely perfectly. I'm tempted to install Mint to see what happens.
I don't know where to go with this. Can anyone help?
