If this all began after the new ram was added, try going back to the original
ram and see what happens. Let's not look for zebras if we don't have to. If that is not possible for some reason we CANNOT rule out the possibility of the new ram being the problem, regardless of what you've tried. Still, we can try some other things. Please do all of the following (and yes, I read your first post):
1) Disable the pagefile. Then boot to the Recovery Console and run chkdsk /r
(as opposed to chkdsk /f). Again, please do that from the Recovery Console. After you boot back into the OS you can re-enable the pagefile.
2) To check the ram, download memtest (http://www.memtest.org/
). Burn it to a cd using a dedicated .iso burning utility (http://www.petri.co.il/how_to_write_iso_files_to_cd.htm
), make sure the cd drive is at the top of the boot order in bios, then boot to the newly created cd and run the utility.
3) Update all drivers. Get them from the OEM websites, not from Windows Update
4) Check for a bios update
5) Then boot back into the OS. Do you still get blue screens? If so, boot to safe mode. If you still get blue screens in safe mode then it is definitely a hardware issue. If not, do the following:
Open msconfig and on the General tab choose "selective startup" (disable everything from loading) and reboot. Does the problem still occur? If not, start adding items back to msconfig one or two at a time, rebooting after each change, until the problem reappears and you'll have identified the offending process. This is clearly a time consuming process, but it is the best way to determine if some process loading with the system is the cause of your problem.
