GTX 970 causing screen lock + hard crash?

I perhaps have an odd problem regarding my GTX 970 (perhaps more specifically, the EVGA GTX 970 SSC ACX 2.0+) and/or my drivers. The issue is that at seemingly random times my screen locks up and and I can't do anything other than hard restart my PC, I can't tab out, ctrl+alt+del, or anything, not even the kb light for caps lock will respond, (caps lock is what I now use to test if my pc's crashed). Oddly, if there is no sound loop, the audio will continue on, for example, if I crash in the Witcher, the ambient noise will continue as normal, no looping, and in GTA, I was in a cutscene when it froze and Lester kept blabbering on as normal. What makes this issue worse is that I can't ever seem to find any dump or crash logs in the minidump folder or event viewer so I was left with no specific or even vague detail as to what causes it. The crashing happens mostly during gaming when playing games like GTA V and The Witcher 3, sometimes it happens while using chrome or another game, but that's only been a couple times.

The issue started about less than a week after I got it when it froze when I was playing Warframe and had to hard reset my pc. During the time I played that game with this GPU, it'd freeze often on that game and no other (that I can recall). I resolved that by using game specific fixes like turning off dx11, using borderless fullscreen and underclocking my gpu. Can't think off having any other problems after that.

I've googled near and far for anyone else whose had an issue similar to mine. From what I gathered online with no dump, error log/message to reference, I figured it could be anything, my psu, my ram, my HDD, my mobo, etc. I've tried all sorts of possible fixes, which have never seemed to work. Most of these include:
- Reinstalling the drivers, with regular installation, clean instillation, cleaned AMD and Nvidia drivers with DDU and did regular and clean installs.
- Updating my mobo bios.
- Underclocking my RAM.
- Underclocking my GPU.
- Extending the power limit on my gpu with MSI Afterburner.
- Checking my temps, CPU doesnt often go over 55c on a hot day w/full load and my GPU goes to 55-65c depending on the heat when playing the more intense games.
- Running memtest86, no errors.
- Running OCCT, again, no errors.
- Buying a new PSU.
- Trying to fix the nvlddmkm.sys errors that I spotted in event viewer.
- Switching back to my ol' HD 7870 (to see if it was something other than my GPU) no crashes, leading me to believe that it is indeed either my GPU or some sort of driver issue.

There might be a couple others I tried but can't remember right now.

So, at this time, that's all I can really say about the issue. If anyone can offer any advice or help, please do. I really didn't want to bother anyone with this, but I'm really at my wit's end right about now, so any help will be greatly appreciated. And if anyone does decide to help, let me know if you need further info, I'll do anything I can to help you help me.

Sorry for huge wall of text, but I want to make sure I have all the bases covered.

And I almost forgot my specs:
CPU: FX 8320 (stock speeds)
GPU: EVGA GTX 970 SSC ACX 2.0+
RAM: 8gb DDR3
MOBO: m5a78l-m/usb3
PSU: ARC-M650

When ur screen locks up do you have google chrome open? the last few drivers from nvidia cause driver crashes and you get a black screen at seemingly random times. Nvidia just released a hotfix but isnt officially published yet. You can download the new driver here https://forums.geforce.com/default/topic/849203/geforce-drivers/announcing-geforce-hotfix-driver-353-38/ I hope this helps as its already fixed my very similar issues.

Lord... I wish you had come to this site before "upgrading" your power supply.

Rosewill are terrible tin cans, most likely the issue. Can you test your system with a proper psu?


Also run DDU clean out all old drivers, then install newest from the website.

Nope, if I had a better one, I'd use it.



Already did that. At least twice now.

Alright, I'll go ahead and try that out and test it over the next day or two.

Ok, well. . . I may have opened up a new can of worms and also *MIGHT* have a lead as to what's causing this.

In short, my motherboard or its IGFX.

In a long-winded explanation: Upon switching my graphics from GPU to IGFX, I came across a problem that I've had for a while but cant fully describe, but I'll try anyway. Sometimes, when certain colors are displayed the monitor seemed to move rows of pixels to the left a few notches, leaving a small flat black or white bar type thing in the empty space. The bars came and went from time to time, as time went on, things got worse in a different way. At times huge portions of the screen, about 3/4ths of the screen from the bottom up would start "warping" when certain colors took up a good amount of the screen. The warping looked like the way tvs do when they get broken in a movie, just without the colored bars. At first when it started happening, I thought it was my monitor just going out on me, but when I switched to my IGFX, the warping took up almost the entire screen, even at times just going black, so when I rebooted my pc, I couldn't see anything, hardly the boot screen, couldn't see when I could log into windows, I only heard the chime, when I logged in, I still couldn't see anything. I had to go back, and from memory reset the bios to use the GPU first since I couldn't locate the battery on my mobo to reset it that way. When I went back to my GPU, no warping issue.

So with that said, I'm going to run some different hardware setups, my cousin lives with me and he's been ordering parts to build himself a pc with similar hardware, just a different mobo. So I'll ask him about temporarily assembling it, with my ram and psu to fill in for the things he still needs and testing a bunch of stuff out on my monitor and his tv. 1) to see if my mobo is the culprit for the freezing, and 2) to see if my monitor is the cause, or at least part, of my other problem (which I didn't know could even be related until now.)

Provided he even agrees to let me do use his stuff, I'm in for a long couple of days. . .
