PC Failure - Supposedly GPU

[Danny2477]

It's not exactly my entire desktop is crashing, instead my GPU fan (I think the GPU fan) goes crazy and I get a message on my monitor saying "No video input" and then it sends itself to standby.

I am assuming this is the GPU due to my PC still functioning, I just can't see anything etc. once I get this message.

Checked my GPU temperatures in both Idle mode, when I'm doing standard every-day tasks (work, YouTube etc.) and both times it's sitting around 42'C . This is when the GPU fan is automatically set to 20% (power wise).
Checking my GPU during playing a game and it goes to around 60'C, also when the GPU fan is at 20% (power wise).

Now I don't claim to be an expert, but I'm pretty sure that's actually fairly cold for a GPU to be running at?

When I bump the fan power to 100%, the temperatures are the following:
36'C in Idle or every-day tasks.
45'C playing games.

This looks to me like it's not overheating, but that's the only thing I can actually think of. I am going to try and re-apply thermal paste to the CPU and see if that makes a difference, although I need to take a trip into town to re-supply so I'm hoping anyone has answers before I go (which will be on Saturday).

My GPU is only acting up when I'm playing games, thus making me think it's failing under stress or overheating. However my GPU hasn't shown any previous signs of failing under stress, and as the temperature checks show it's not overheating.

PC Specs:
Intel Core i5-3570 3.40GHz
NVIDIA GeForce GTX 760
ASRock Z77 Pro4

Can't find any other specs, just know I have 12GB RAM and 1TB HDD.

TL;DR Supposed GPU failure, temperature checks show nothing overheating. Suggestions?

can we know what psu u have and did u update ur driver??? try clean installing drivers...

You are correct saying that those are goods temps, so overheating isn't the issue. The only other things I can think of is a driver or a power supply issue. A friend of mine had a rig doing the exact same thing and we had to replace his power supply. But before you go and buy a PSU try completely uninstalling your drivers(using DDU in safe mode) and reinstalling drivers, and if that doesn't work, your GPU is either dying or it could be the PSU.(not entirely sure)

what your seeing could be a power or a gpu failure. gpu when you tuirn them on they have a firmware and a post built into the gpu. the firmware needs to check to see if there fans are working and can sence them,. most nvidia gpu will go to 100 pecent at post for a few sec then ramp down to 20-30 percent of max speed. if the gpu looses fan info the firmwasre will send info to the fans to max out to keep the gpu for cooking.

set it to sensor and logging and watch your 12v rail in your pc if it drops below atx spec your gpu will reset. if you had a over heating cpu you get a cpu over heat warning from the bios then a full shutdown of the system.
