From time to time my pc freezes, and is then unresponsive unit I restart it.... I've reinstalled windows 10 and the problem persists, and I've swapped gpus and the problem persists. Any suggestions as to what could be causing this?
Power supply corsair hx1000i
Motherboard evga z170 ftw
Ram corsair vengeance 2133mhz
Cpu 6700k
Gpu 980ti hydro

i have a custom loop and temps are low so I don't think it's overheating.
The freezing happens in game and out of game.
Occasionally when it freezes a buzzing sound comes from the monitor.

Hello VladimirPutin and welcome to the Forums!
 
Try testing the RAM one stick at a time in slot 2 (second slot from the CPU) and try to replicate the freezing issue. If none of the sticks appear to be causing the issue then check the 12v rail from the PSU.
 
Go into your BIOS and look for the +12v  reading, this is typically under 'PC Health Status', System Monitor, Hardware Monitor'. A healthy reading is between 11.5 - 12.5v, and stable. It should not fluctuate rapidly more than .05v and should hold steady for at least 10 seconds.

Thanks, so ram one stick in at a time and use my pc as I normally would, or use a benchmark like 3dmark with one stick in? With the benchmark acting like a stress test

tried looking at bios and the reading is 12.036 and very stable, will try ram now

You will want to try to replicate the freeze. If this happens during benchmarks then I would try that. If this typically only occurs when gaming then try running games.

ok the freeze seems to happen randomly so I will try using my pc generally with each ram.
Another note, I ran memtest86 for two hours with zero errors. I have just tried 3dmark and as soon as the test loads there is a faint ticking sound coming from my motherboard area...maybe the ram... not sure if this is relevant or not.

For 2 sticks of ram that I have now tested so far my computer has frozen... So probably not the ram...

#1 Check your hdd/ssd for errors.
#2 Check your cpu by running the IPDT.
#3 Make sure your ram is running the correct frequency, timings & voltage. The frequency, timings & voltage set inside the BIOS should match the JEDEC stickers on the sides of your RAM modules...
 

It can be Power Supply Fault also. I had once 5 year old PSU 1300w and suddenly It started to giving me problems. After I exchanged it is went back to normal. I had 3 PSU in the past that started giving me problems after 5 years.

Disconnect that corsair link junk if you have anything corsair in your loop and see if that helps I tried waterblocking my CPU in Air vs WC testing and destroyed the cooler corsair makes some pretty crap coolers known for flaws, leaks, and cos link issues, I know the CS link was making my system weird during test but
 
Air destroyed Water in my test on temps by far
