I was playing a game when my game froze a couple times in the space of 10 seconds and then all of a sudden I got a blue screen which caused my pc to restart which soon followed by a black screen saying 'Disk Read Error' then later went to an all black screen with a white blinking underscore at the top left, when I restart my pc I get the Dell boot up menu and I tried running diagnostics and it says there is a warning next to hard drive and also says hard drive not detected. I'm not sure what to do, any help or suggestions?

That's a hard drive failure, and there isn't really anyway to fix it.

My laptop does this occasionally, and after a few restarts it does work again. The hard drive is failing but hasn't failed completely yet.

Check this thread out, should help.
