Sep 18, 2021
I have a pc i bought around some 4 r 5 years back it was smooth until some mnths back my hard disk failed then i bought a new hard disk but every time i use it my screen was getting freezed every now and then that is even while just watching anime in chrome and also is very slow, when i try to restart, the os was getting corupted and it has happend like this thrice then i called a pro and he said the new hard disk is faulty so i claimed the warranty for the hard disk but even now i have the same problem i also got blue screens multiple times before and after the claim of my hard disk any help??

my specifications are:
kingston 8gb ram
i5 processor
seagate skyhawk hard disk
gigabyte 4gb 1050ti graphic card
asus motherboard(4 ram slots)
Run memtest86 or memtest86+
They boot from a usb stick and do not use windows.
You can download them here:
If you can run a full pass with NO errors, your ram should be ok.

Running several more passes will sometimes uncover an issue, but it takes more time.
Probably not worth it unless you really suspect a ram issue.

My guess is that you have a software issue
