Computer having random freeze moments!?

[Savatsan]

So my pc gets some random freeze moments that some time last a few second sometimes last so long that I cant wait anymore and I just reset the PC. While frozen nothing responds and sometimes I get a very loud sound coming from the speakers sometimes not. It happened to me while browsing internet watching movies or gaming. What I have noticed during the last freeze is that my hard drive light stops blinking totally and hard drive is my main suspect currently since I have also experienced issues when waking up the PC from sleep. The pc starts running, all components are working and fans lighting up but mouse keyboard and the monitor dont get any signal. Issue is fixed when I press the restart button, the PC it self doesnt restart but loads up from sleep totally normally. Any help or suggestion is highly appreciated! Here are my specs:
Motherboard: ASRock N68-C FX
Processor: AMD FX-6300 Black Edition
GPU: AMD Radeon 7750 2gb ddr3
PSU: 350W (not sure what manufacturer)
RAM: 2X4 GB kingxton fury hyperX 1600Mhz
1TB WD blue hard drive (around 1 year old)
OS: Windows 10

you're CPU is more than likely overheating, AMD chips are known to run very hot, and if you're using the stock AMD cooler that is definitely not helping.

I doubt that since right now during winter it doesnt get over 50 degrees C, I havent overclocked it and the heaviest task I put it up to is running Dota 2. I was monitoring carefully last summer when it was around 30 degrees in my room and I was playing GTA V it was still running with in the limits.
