Artifacts During Boot (post + Windows Login Screen + Windows) Until Second Monitor Is Recognized.

Hello,

In the past few days I have been experiencing a few different issues.

First I noticed that my secondary monitor (DVI-I I believe) would randomly turn off for a second and then come back up.

After swapping around the two DVI cables, it is indeed related to that specific output from my video card since my primary monitor exhibited the same behavior.

After a couple days, I started getting green artifacts during POST, Windows password screen, and in Windows until my secondary monitor comes up, then they both reset with no artifacts.

The artifacts start off with full screen coverage on my primary monitor, go to 3/4 screen coverage during the login menu, and then disappear once the secondary monitor becomes active.

If I leave my secondary monitor unplugged, from the video card, the artifacts cover my entire primary monitor and do not go away after boot.

I tried cleaning the contacts on my GPU as well as a different PCI slot on the motherboard with the same results.

Are there any suggestions I should follow before RMA'ing my video card?

Thanks!


Specs:
Windows 10 Pro 64 bit
6GB RAM
Asus Rampage III Formula Motherboard
i7-970 processor
Corsair H80i cooler
EVGA GTX 770 4GB Superclocked GPU
Drivers: 359.06 nVidia
EVGA SuperNova 1300G2 PSU
Samsung 840 Pro 256GB SSD
Seagate Barracuda 1TB HDD

 

It certainly seems like the video card is to blame.
If possible, try it in another PC to be sure.

 

I suspect vRAM or old driver issues.

Have you updated to the latest nVidia drivers?

How did you uninstall older drivers? (DDU?)

If you goto the Hardware Monitor section in BIOS what temps and fan speeds are you seeing before OS?

Whilst in OS can you run GPU-z and or HWMonitor (both are free) and post GPU temps?

 

If the above does not help....
Nice system, how old is the power supply?

 

Thank you all for your input.

Eldon, as you suspected, the video card was the suspect. I purchased a $35 piece of junk PNY GEFORCE GT 610 from Best Buy today and tried it out which produces no artifacts.

I have put my EVGA card in the mail for RMA and will be receiving a replacement unit within about 10-15 days time.


Bold Eagle, I had indeed upgraded to the latest drivers (listed in the main post) with the exact same output, and all temperatures, voltages, fan speeds appear to be normal during all forms of operation.

DOA, THANKS! The PSU is about 3 years old and is, by far, overkill, but with such a great warranty, a fully modular PSU which is basically limitless on power was the proper choice for me compared to my BFG PSU which was missing many of its modular cables.
