yup yup yup
usually bai basta ang BSOD nimo mag lain2x common issue na cya with RAM but with REGISTRY FILE FAILURE
since u already isolated the problem with the OS definitely it's ur hdd, try gud ug lain nga hard drive ani nga
computer with the same RAM so u can say dat 100% sure jud nga ang hard drive ang guba...with a KNOWN
GOOD HARD DRIVE ok gani cya so kabalo na jud ka unsa ilisan...
gud luck.
