I really can't figure out what is causing hard freezes on my system. They are very random, and not when playing games or doing some stress computational problems. But almost every time I run windows backup, after about 10-20 minutes I get hard freeze with a sound of whistle on speakers. (but also when not running backup, but those freezes are not as frequent, but still have same whistle sound).
It looks like is something on HDD. I have two HDDs installed, both Sata-2, AHCI mode. I've disabled the old one first, but it also came down to hard freezing up a system. Now I think that is possible that newer HDD is problem causer. Disk is Samsung F3 1TB. How can I check disk for possible errors?
Is there any possibility that the problem is somewhere else? I have updated all the drivers and system is pretty clean. I have no other problems whatsoever.
Thank's!
