Hi,

 

I suspect I have a failing GTX 690 (it wouldnt be the first time) as I am occasionally getting random black screens following by a reboot and the saved dump refers to video hardware error. 

 

This is usually but not always brought on by gaming.

 

Anyway, before this started occurring, and since, my CPU fan seems to suddenly cramp up to ridiculous levels when doing something which may put it under pressure. The only thing is, this never used to be the case, my machine has always been much quieter than this.

 

If I replace my GPU, but my CPU fan continues to be stupidly loud at times of stress, what are the likely causes?

If the GPU is heating up the surrounding area, the CPU could be running a bit hotter whiich would cause the CPU fan to spin faster to try and cool the CPU back down.

OK, i downloaded coretemp and the readings of my cores are all 94 degrees when just viewing a simple webpage. this seems way excessive. Can an overheating CPU cause a black screen but then the error report "thin" it was a gpu error? Or is it likely that the GPU is overheating my CPU? 

 

Or are both broken? lol

Yep, 94°C is a bit steep. Download, install and run Speccy. Click File > Publish Snapshot > Yes > Copy to Clipboard and then paste in the URL you just copied into a Reply to this thread.

That 96°C on your Intel Core i7 3820 is NOT good. That's close to the auto-shutdown temp, (so that it doesn't melt and start a fire).

 

The 32 & 33°C on your GTX 690's are good.

Yeah and the motherboard was 104 degrees!

This was all while mostly idle too. My question is:

Could the auto shutdown report as a video hardware error even when it's not? Because whenever I've had an auto shutdown that's what's being reported in the error log.

Thanks

Apparently so. It's the CPU that's too hot. And you need to find a solution pretty quick before you fry it, or start the house on fire.

Just to let you know my machine is with a repair shop who are diagnosis for me as I'm far too busy with work to spend time on it.

Thanks for the advice you gave :)
