Not looking good for the GPU.....
Slowly getting worse -- BIOS corruption issue (Sajin mentioned) ---- maybe a poor connection somewhere that is getting worse
Short of testing the GPU in another PC or another GPU this PC ..... (my kitchen sink list)
Your system should not be pulling even 500 watts, so PSU should not be hard pressed -- how old is it ?
Any large appliance on the same circuit as the PC ? (laser printer, microwave, A/C, Fridge)
Win 10 ? - if yes turnoff the Xbox DVR (on by default and its a resource hog)
Your MB has sound and Nvidia drive will load sound drivers - Check Device Manager -- (only run 1 sound driver for stability)
Which Nvidia driver have you tested ? ( Try 378.92)
Run
DDU in default settings safe mode, with reboot when changing drivers
When you Install Nvidia driver --
Use Custom install --
Only GPU driver & PhysX --
Clean install ---Only at this time
Your running EVGA Precision OCX ? version 6.1.14 ?
Add 30 - 40 % voltage and test
If using OCX - turn Off --- OSD
Confirm GPU/card is fully seated and locked in PCie slot -- test in other slots
Make sure power cables are fully seated and latched -- sometimes they get tight before that are in all the way.
You gaming online ? if so turn Off hardware acceleration in your browser
How do you have Nvidia Control Panel setup ?
