His bluescreens isn't caused by ram, this is a hardware, driver, software issue. So if you have reinstalled windows, then I would think driver would be out of the question. unless you are using old drivers to reload the system. So we are looking at this being a hardware failure or software. Have you loaded any software since the reinstall? You may want to reinstall windows again but this time don't install any software and run the machine to see if it bluescreens. I'm betting you have a hardware issue. Run a diagnostic on the hard drive to make sure its healthy.
