System freeze

Hi Gang,
My specs are i5-6500, GTX 750 Ti, 8 GB DDR4, Samsung EVO 250 GB SSD, B150M DS3H mobo, CX 430 PSU, Windows 10 Pro Ultimate 64 bit.
I know they are kinda old, but still work well with the games I play - POE, Last Epoch, PSO2 etc.

Of late, i am experiencing full system freeze after few minutes of gaming. I have to force reset the CPU. It boots normally and logs in to windows.
I have all windows update done, including mobo drivers and GPU drivers. I even tried using older GPU drivers, but no difference.

Few entries in windows event viewer throw up -
Error 10010 The server Microsoft.SkypeApp_15.68.96.0_x86__kzf8qxf38zg5c!App.AppXtwmqn4em5r5dpafgj4t4yyxgjfe0hr50.mca did not register with DCOM within the required timeout.
Critical 10111 The device HID-compliant headset (location (unknown)) is offline due to a user-mode driver crash.
Critical 10110 A problem has occurred with one or more user-mode drivers and the hosting process has been terminated. This may temporarily interrupt your ability to access the devices.

I ran OCCT tests, and it freezes within minutes on CPU/Power tests. I have attached a screenshot. PSU rails seem to be ok, and temps are not bad. Any advice on what could be the issue - PSU, NVIDIA drivers, Windows update, etc?

Cheers
V

Did you do any undervolt/overclocking? You might want to reset these and test.

My suggestion is to boot your PC in safe mode and run these stress tests first. If it still crashes then it suggests something might be wrong with your hardware or BIOS. You mentioned these are old parts so I wouldn't be surprised if something is fried. If it doesn't crash and appears to hold up fine, then it suggests software issues like drivers, SDKs and the like

Nope all are on stock settings. If i just use the system for Netflix/Primevideo/Youtube it will run without any issues for hours. Its vexing not knowing which part to fix .
