if you're blue screening it could be all sorts of things
my first stop would be memtest, blue screens are often memory related
if memtest runs fine (about 10 passes) then i'd check the voltages, undervolting can also cause. the 3, 5 and 12 rails. there should be a screen in BIOS for you check them, if not then HWmonitor
blue screens can sometimes be caused by conflicting or faulty drivers. so might be worth uninstalling your chipset and all drivers and doing clean installs of them.
