Artifacts into Freeze into BSOD

Hi all,

I'm trying to find the problem with my nearly 7year old rig, which has been running smooth up till a couple weeks ago.

So my PC started showing artifacts every now and then, eventually freezing up and on occasion BSOD. Error : VIDEO SCHEDULER INTERNAL ERROR.

Suspecting my GPU, I started cleaning out any dust and applied new thermal paste to both CPU & GPU. Next checked for any possible malware, updated all drivers and checked for disk corruption (chkdsk&DISM&sfc commands).

Since the problem remained, and my temps seem totally fine (60°C gpu/cpu right before freeze), I formatted both disks and performed a clean Win10 install. The problem still remains. Next I turned down all my overclocks and downloaded the supposedly best driver for my specific graphics card. No change.

Now after a lot of testing I managed to narrow down when everything goes banana's. I can use my PC an entire day watching video's, browsing or working without any issues. I can even play an evening of CS:GO, let's say 3 hours, without issues. But the minute I start a game of Hearthstone (even in low settings), or 3DMark to benchmark test, everything goes apeshit. Now my guess is that nothing happens during CS:GO because it's mostly CPU based, but correct me if I'm wrong.

Now I have some friends saying my GPU must be fried, others saying it must be the Motherboard and others it might be the PSU. I don't have any spares laying around so if anyone could help me find the specific problem...

One thing I have noticed is that the GPU Power drops from 34% to 0% right when before a freeze. Specs : * CPU i5-4670K * GPU nVidia GTX780Ti * PSU HX 850W * RAM 16GB * SSD 120GB + HDD 2TB * 2 extra Fans + watercooled CPU

Thanks already!

Its usually a corrupt driver or system file but your clean install should have cured that, however it's worth running a hard drive scan to check for bad sectors

Succesfully scanned. No errors were found.

If there's still somehow a corrupt driver, I honestly have no clue how to narrow it down.

go to a game that will eventually freeze and if possible put it in windowed mode , next open task manager and click on performance tabs , keep both items open side by side and look for spikes in any of the graphs whist waiting for things to freeze , from what you have done you seem quite knowledgeable so the graphs might give you a clue to whats going on.

Look in reliability monitor for error reports that might give you a clue as to whats happening.

do windows memory diagnosis to eliminate faulty ram , if it says its faulty you will have to repeat the test using one ram stick at a time to find out which one is faulty.

Do you use nvidea experience program that is part of the nvidea driver download. If you do get rid of it , it is a pain in the butt , do g card updates manually and during install choose custom and untick nvisea experience.

Finally , open device manager and look if you have any yellow triangles on anything.

A lot for you to read but I hope this helps.

  • Screenshot of all monitors before the crash >GYAZO<
  • Screen the moment everything freezes, before BSOD >GYAZO2< (GPU Power suddenly drops to 0%, but why??)

  • The Windows Memory Diagnostic tested the computer's memory and detected no errors

  • I didn't download the Geforce Experience, never liked it. Just the drivers.
  • Device manager was clean, all drivers up-to-date, no errors.

is there a sare powr plug on the PSU you can swap with the one on the graphics card?

I took home a spare PSU(+cables) from work to test the same rig today, still the same result.

Screen froze less than a minute into the benchmark (Time Spy), artifacts as well.

How confidant are you that your PSU is delivering a consistent voltage?

The spare one was fresh out of the box
