[SOLVED] Computer freezing after 3 years of clean running

Recently, my computer has begun freezing at what seems like random intervals until a hard shutdown and reboot. I originally thought it was a temp issue, but it recently froze while sitting around 50C.
I installed a new harddrive, and thus a new copy of Windows 10 Home. I haven't run memtest, though I plan to today. When it freezes, there is no sound loop.
My motherboard is updated to the latest BIOS.
Specs:
MOBO: Gigabyte Z97X
CPU: Intel I7 4790K
Ram: 16GB(I'll check the brand later)
GPU: NVidia GeForce GTX 970
2 HDDs both are: WD Black 2TB (https://www.newegg.com/Product/Product.aspx?item=N82E16822236624)
PSU: Corsair something... 600W I believe
Due to the chipset of my current mobo, I would have to purchase a new mobo and cpu if either is the cause, as local sellers don't hold an LGA1150 chipset cpu.
It should be noted that I have the stock Intel heat-sink fan for the I7 4790K.
 
Solution
Try other software to check the cpu temp, HWiNFO https://www.hwinfo.com/download/ 80C is little bit higher for the i7 4790K, that maybe the problem, may consider to buy the aftermarket cpu cooler, usually the intel stock cooler will have problem to handle the i7 4790K, and if the PC has overheat, drivers (GPU), hard drive+ OS, etc. those will cause PC frozen.
1) update the chipset driver https://downloadcenter.intel.com/download/20775 also use DDU to uninstall the GPU driver in safe mode, then reinstall the GPU driver.
DDU https://www.guru3d.com/files_details/display_driver_uninstaller_download.html

2) use MSI afterburner to double check the CPU and GPU temp during the game, if you had two monitors, then open the Afterburner in other monitor. If you didn't have two monitor, and you can set the temp monitor open in taskbar or on screen. Just make sure the temps are fine, because pc will has that problem, if the temp is higher.

3) Open the case to check what exactly PSU you had, because if the PSU has problem to handle your PC, it will cause the same problem too.

4) How about the memory test?

PSU is the corsair CX600M, I updated my gpu to the latest driver last week... Not sure if it's worth trying again, I'll update my chipset driver now, as for the memtest, I need to find a usb to reformat for the iso
 
Because you already done
1) overheat or not, and you said the cpu temp is around 50C. Do you check the GPU temp? you can use the MSI afterburner or the software that comes with the gtx970.
2) The drivers, you did that too ( GPU, chipset, BIOS, etc)
3) If you installed any gigabyte utility software, just uninstall it (them), because they may cause the problem sometime or somehow.
4) You had two black HDDs, may try to disconnect one, only use the ONE had the OS. Also check the OS with System file check (SFC), how to https://answers.microsoft.com/en-us/windows/forum/windows_10-update/system-file-check-sfc-scan-and-repair-system-files/bc609315-da1f-4775-812c-695b60477a93
5) If you used MSI afterburner, may try to set the power limit ( for GPU) to 80-90%, if the PSU is the old version CX600M with green/white label.
6) One more if you oc the i7, reset it to 4ghz.

My i7 isn't overclocked, average temp for the gpu is around 70 during games like CSGO, my computer was freezing when I only had 1 WD black, as for the sfc... It may be worth checking out, although the issue existed before and after a new drive with a fresh os installation. I could try limiting the power to the gpu

Also, an interesting thing to note is, iCue(Corsairs utility software), when having "Show Connected Devices" unchecked will display all corsair devices viewable by the software, even if you don't have them(Shocker, I know). What's interesting is, it will display all stats for cpu temp, psu temp, power in, power out, voltages, fan rpm, and just a lot of useful info. I'm not sure how much of the psu info would be helpful
 
I'm not sure how much of the psu info would be helpful
Any PSU info from that software, something +3.3V, +5V, or +12V. You can boot into BIOS to check those voltages too, you want to see those voltages should be within +/- 5%, like +3.3V, it should be like between +3.1V to +3.4V. Otherwise the PSU is not good.

Also did you have other hardware, like pcie sound card, LAN card, etc. If you had, try to remove them, then test the PC.

I only have my gpu in the pci slot, no other hardware is present. Also, the corsair information appears to be incorrect, as RealTemp showed my pc at 80C while playing CSGO, while the Corsair utility was sitting at 30C, which... Yeah no, my case felt warm
 
Try other software to check the cpu temp, HWiNFO https://www.hwinfo.com/download/ 80C is little bit higher for the i7 4790K, that maybe the problem, may consider to buy the aftermarket cpu cooler, usually the intel stock cooler will have problem to handle the i7 4790K, and if the PC has overheat, drivers (GPU), hard drive+ OS, etc. those will cause PC frozen.

Yeah, my plan is, if it is an overheating issue (Which I began to doubt when it was running fairly low in terms of heat), I'll buy a cooler... Otherwise I may need to buy a new mobo and/or cpu, due to socket limitations

Looking at HWiNFO, the temperatures are running pretty high right now, even though I'm only playing Starbound... Yeah I may need a new cooler. I've already said this, but I really appreciate your help through this whole situation
