I've updated my specs but due to it being a custom made computer, i'm not very sure about a few of my specs. As for the history, the computer might have BSOD once in a few months before i bought my monitor. After which, the BSOD starts happening rapidly. Sometimes it happen once a day/2days but sometimes it happens continuously, the moment u boot up a few minutes it crash. I've not change any hardware but i've downloaded many software.
