So I was on my computer and the computer looked like it glitched out then the screens when black. The computer at this time was still running. I waited some time and it didn't change so I turned the computer off and back on, it sat at a b2 code for ahile then moved to the a2 code where it sits at. Im not seeing any logo like I was before. I tried turnning off power, clearing cmos, starting safe mode but no luck. Im not exactly sure whats going on atm. please help.
Update- Im thinking my os hard drive is failing but im not certain. Im hearing a weird noise coming from that hard drive, but when I unplugged it I still get the same results
