Desktop system freezing constantly

One of our workstations keeps freezing. it starts with sudden lag and eventually just stops responding for infinite time. Its not upon doing certain actions its just very random. processor, RAM are 90 % FREE.
I have run virus, malware scan with no threats identified. Ran sfc check as well nothing.
HD SMART status not reporting any HW related errors either and neither event logs showing any thing.
I want to avoid formatting this pc at all costs. any ideas what else i can do

OS is windows 10.

Try DISM. Open cmd.exe with Run as Administrator and run:

dism.exe /online /cleanup-image /restorehealth   Allow to complete, restart and test.

Then, if that does not work, run a Windows 10 Repair Install and Keep Everything.

Go to the Media Creation Link

https://www.microsoft.com/en-us/software-download/windows10

Windows 10 is running, so click on the Download button (not Upgrade Button, select Open (Run) but NOT Save. Allow the program to run. Allow drivers to update. Then select Keep Everything.

Random problems can be difficult to troubleshoot because their occurrence cannot be forced.

I would start simply by reseating EVERYTHING in the computer except the CPU.  RAM, expansion cards (especially video), power connections.  Also, make sure all the fans - case, video card, CPU - are all working.

If the problem persists, I'd try replacing RAM, and then video card.  

If the problem persists, I'd try replacing the power supply.

If the problem persists, I'd try replacing the motherboard.

After that, it's just the CPU.

Check to make sure the cooling fans or running. It may be overheating and locking up.

No problems with temperature. All the temperatures are well within range checked my HWMonitor

Which means your CPU and maybe an ambient temperature sensor are okay.  A failing power supply fan, or video card fan might cause problems you won't notice in your hardware monitoring product.

Paul, HWMonitor reports external Nvidia GPU temperatures as well. In my previous experience PSupply fan failure doesn't slow down system. It just stops working one day. Not trying to discount your suggestion, but i hardly doubt that those two are the causes.

Do you have 2 antivirus installed in the system? If yes, remove one of them will fix the issue.

One more thing, Update the BIOS Firmware.

It has been suggested by John to do an inplace upgrade. That does not hurt, do it for a test.

in such a case - you need to eliminate devices.
so i suggest to disconnect all external and internal devices  you can do without :
cd drive, extra disks, printers, scanners...
if possible run with 1 ram stick
you can also test if it happens in safe mode

Unfortunately none of the solution posted resolved the problem. Problem was with Google Chrome. Very Weird. as it didnt had to be running for system to freeze. It would just freeze randomly. I had to uninstall it completely and problem disappeared. Tested it for over 10 days.
