i already used HDD scan before on my hard drive and the tests didnt returned any errors at all. this memtest program doesnt boot my pc into what it supposed to boot into. i have run chkdsk /f /r many times as well. ill recheck again later for the memtest part although my pc parts are just new and i think there are just some buggy drivers not my hardware is at fault here. I am using WhoCrashed and BlueScreenView apps as well for troubleshooting these persistent BSODs.
