BSOD randomly error 0x00007A

So few weeks ago my Laptop was super slow and basically wouldn't respond to me at all during start-up. Decided to re-install Windows again which fixed the problem, now I am running into another issue.

My laptop runs for like an hour or two smoothly and then all of a sudden it gives me a BSOD error 0x00007A Kernel_Data_Inpage_Error. It happens very randomly, or when it starts to freeze. I also noticed Windows is a little bit slower, not sure what is causing this problem.

Whatever happened, it is only temporary.
You need to replace the hard drive as it is failing.

Like I said, what you currently experience and what you will experience the next period is only temporary.

It is strongly adviced to replace the hard drive a.s.a.p., I have no doubt that you soon will get more problems than BSODs.
