What is the complete computer specifications that you have? BSOD can be also caused by ram failures so try testing the ram at Memtest86+. You could also have a old driver so try updating all the graphics and sound and every other driver to the latest and then see if it works, also try to repair the os if possible to eradicate this issue.
