GTX 970 Crashes randomly / No video output; PC keeps running

[phillpower2]

Thanks respectively for the additional info Feri and also to Veeg for the additional support (y)

I Auto-Overclocked my CPU in the BIOS if this helps.

Restore the MBs default factory settings in the BIOS and make sure that your Windows power plan is set to Balanced and not High Performance, the former may be listed as “most stable” or similar in the BIOS and the latter is a form of OCing that can cause overheating and system instability in general.

You have high temps + high CPU usage for a computer not under load, both could be the result of a weak power supply and/or poor case cooling and the OCing, btw, your present PSU is not even Bronze efficiency rated and could potentially be 8+ years old and therefore 5 years out of warranty, it should have been replaced before now and most certainly before adding the GTX 970, 2009 PSU review here

A GTX 970 requires a minimum of a 500W PSU that has at least 30 amps on the +12V rail, when independently tested back in 2009 the PSU could only produce 456W and this will reduce the older the PSU is, the amps produced would and should still be fine though.

I have to admit I don’t have the best fan setup in my case

Can you post the brand and model name or number of your case so we can check for any possible cooling fan improvements

We could do with some other system info as well;

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

tory settings in the BIOS

I already did that. The 970 crashed before I overclocked too, so that’s presumably not the issue.

I tried that and got another crash. To my knowledge, everything else than “High Performance” is just limiting, not overclocking. I will not put it on Balanced as the drop in performance is not an option for me.

I was running a game whIn i took the screenshot as I assumed you wanted the temperature readings under load.

That could well be as my father gave it to me, and he was using it before so 8+ years is a good guess.

Wouldn’t the 970 crash right away if it didn’t have enough power?

I have absolutely no Idea what this case is called. It is just an old generic case. One case fan is installed, but my case is open pretty much all the time since overheating sounded like the solution to me. Which apparently isn’t the case (no pun intended). The fans of the 970 are barely running and the temperatures never rise to a critical level.

Any updates for us?

The crashes happen very frequently now, but not in all games. They seemed to only happen on higher setting but now it doesn’t matter.
The crashes are reproducible, so if someone can provide a method, I will be happy to log what the GPU is doing.

It is presenting BSODs when it crashes?
