Okay after a new tests i found out some interesting things:
One time when i booted up my PC, it ran perfectly fine without issues only for that boot up.
Another time it failed to start with the message "Boot mgr is corrupt the system cannot start"
Another time i had started the computer and it took 20 seconds for my screen to turn on responsive and my computer's power button (i attempted a turn off by holding it down) was unresponsive, very new to me!
and lastly one time i booted my PC, it loaded just fine but explorer.exe failed to load up as well as other start up items such as my anti virus.
? does this mean hard drive is screwed? most likely right? (just wanna hear what you guys think before i run the tests from Initial Hardware Diagnostics
