Im having the exact same issues. Re-installing from scratch isn't going to do anything....
My sister got this PC from COSTCO, run fine for few years but then started to crash occasionally, then more often.
Last couple of years have been unbearable, blue screens are so random and often that no works is been done on this PC. Pretty much is just an email reader and sometimes is not even good at that.
2 weeks ago I did a fresh install from factory partition, then installed all important Windows Updates. Still crashed. Refused to update Service Pack. MS offers a tool to do a clean SP uninstall but it then refused to install SP by itself. Ugh!
PC still run even without SP but is very unstable.
I'm having a technician upgrade from Vista 64 to Windows 8 hoping it would mitigate these issues. I'll report back.
