It's been a while my pc randomly freeze making buzzing noise, then my 3rd drive (an old hard disk) died so I thought it was the problem and I removed it.
But it was not because yesterday I experienced many of those random freeze while playing league of legends, something like 8 times during the day, so that's what I unsuccessfully did:
  • Lowered game video settings
  • Uninstalled game from D: (hard disk) and installed on C: (ssd)
  • Checked for errors on file system by drive windows properties
  • Installed windows updates
  • Installed newest GPU drivers
  • Ran "sfc /scannow"
  • Ran windows memory diagnostic
  • Ran stress tests for GPU and CPU meanwhile controlling temperatures
But still I didn't detect what's going on. It happens more frequently when I play league of legends, less frequently on valorant, but never happened meanwhile playing magic arena or watching netflix, youtube or during work sessions. Any ideas ?

My config:
CPU: AMD FX 8350 Black Edition (3 years old)
GPU: Sapphire Nitro+ RX 580 (Newest of the build - 1 year ord)
MOBO: Gigabyte 970A-UD3P (Oldest of the build - 5 years old)
PSU: Corsair CX600V2 ATX Bronze (3 years old)
RAM: Corsair Vengeance 2x4GB DDR3 1600mHz + Kingston 2x4GB DDR3 1600mHz (5 years old) - I don't think different rams are the problem because i have them in for at least 2 years without any issues
DRIVES: Samsung SSD 850 EVO 250GB + Seagate Hard Disk 1TB 7.2k rpm (5 years old)
