Friend told me it was the HDD.
The PC is mostly NEW.

THE PC freeze alot all of sudden and everything become slow.
Is there a way to know if it caused of the HDD?

I have no malware bytes/virus in my PC.

somehow i doubt that.

anyway, check your temperatures

PC wouldnt open all night...

the hard drive has nothing to do with that.
post computer components & temperatures.

Do me a favor and boot the computer in safe mode, and download the latest version of malware bytes and run it again but in a full scan. If it shows clean then it could be a problem with the OS. How old is New? Also, keep in mind that it also could be the HDD.

I did all those checkup with friend earlier in the day and its definatly the HDD.
The PC dont overhear and has a normal temperature.

what did you actually try?

It doesn't go upper than 45~ Celsius at 50% load
Windows had detected a couple hard drive related errors itself and it recommended to back up files
Since it has been a few years since he has his HDD and we live in a society where planned obsolescence is promoted,I can definitely tell that it's the Hard Drive.
It's time for a change

This <-

Google "hd tune 2.55 download" and find out if your drive is fucked.
Or get a witchdoctor to wave chicken bones over it while you make meaningless political statements to figure out what is wrong.
