Windows 7: Windows randomly freezing without BSOD

Windows randomly freezing without BSOD


From quite some time I'm having issue with my PC.
Windows just randomly freezes on me. It happens during YT videos, playing games, watching movies and even right after booting up. There is no BSOD, just freez (cannot move mouse, start process manager, reboot PC in other way than pressing power button or unpluggin it from socket but what's more interesting if this freeze happens during game there is still sound coming in O.o)

I tried to find problem myself - running memory tests and "burning out" processor didn't bring any additional info. Even replacing graphic card and power unit didn't solve the problem so I decided to ask for help.

Here's what I have inside my PC:
  • MB AsRock Z77 PRO4
  • System drive Vertex4 128GB SATA3 2.5'' MLC
  • HDD #1 Samsung HD502HI
  • HDD #2 WDC WD10EURX-63FH1Y0
  • RAM 2x GR1333D364L9/8G
  • Intel Core i5-3570, Quad Core, 3.40GHz, 6MB
  • Cooling Noctua NH-U12P
  • GPU Radeon R9 290 OC 4GB
  • Power unit Corsair RM 750W 80+ modular

If I can provide any log files please tell me what you need. However, this issue happens 100% randomly - sometimes it strikes 4 times a day, sometimes nothing wrong happens in a month ;x
