I'm about to break my computer - help me not to

[ujustgotsauced]

Hi, I just built my first pc and I've run into a fatal problem with my graphics card. 

 

I tried loading into several games, but my computer kept crashing and restarting after just a few seconds. I confirmed that it was graphics card related after running Unengine Heaven benchmark, causing my pc to crash/restart in a similar manner to when I loaded other games. 

 

To my knowledge, my temperatures are completely fine <50C for both CPU and GPU, my PSU is quality/overkill, I'm using a DP cable to my monitor, and the latest graphics card drivers from Nvidia's website. 

I fresh installed windows 10 and have only downloaded steam, origin, heaven benchmark, and afterburner.

 

What could be causing my games/benchmarks to crash immediately and turn off my PC? I'm desperate for a fix before I give up on this pc. 

 

Relevant specs: i7 8700k, EVGA FTW3 1080Ti, Seasonic Focus Plus 750W Gold 80+ PSU, 1440p 144hz monitor.

Have you overclocked your graphics card?

[ujustgotsauced]

Not manually. Core Clock/Memory Clock on afterburner is showing +0 right now. Base Clocks look to be just over 1500MHz with Boost around 1700 MHz.

It's a long shot but I have seen it be an issue. How old is the PSU?

[Brooksie359]

Is your CPU overclocked?

[tarfeef101]

Even heaven still puts a non-zero load on your CPU

I'd start by confirming it's a GPU issue by running a CPU/memory intensive test for a while. Make sure they are solid. 

Then I'd look at the PSU -> GPU power, the PCIe slot on your motherboard, the GPU drivers, etc

[ujustgotsauced]

My CPU is very lightly overclocked to 4.6 GHz @ 1.25 V. The PSU is new. 

 

I will try to test the CPU by resetting back to 4.4 GHz. Any recommendations for CPU/memory intensive tests?

Set everything to stock speeds then test. If you wanna stress the CPU use P95 Small fft

Just set your CPU to stock. Also set your ram to stock as well. By that I mean set your ram to 2133mhz. 

[Brooksie359]

Also set voltage to auto not fixed when you set your clocks back to stock.

When I install EVGA Precision without any other input, my 1080 boosts past 2000mhz which is unstable on my Gaming SC with nvidia's non-adjustable voltages and power limits.

 

I would load "optimized defaults"(or something similar to that name) in your bios and then uninstall afterburner, DDU and install the latest Nvidia drivers then start from there.

That is strange. I know with afterburner installing the program wont increase the boost at all until you overclock it. Seems weird that just downloading the program would make it unstable. 

[ujustgotsauced]

So I just ran Prime95 for 5 minutes. I reset the bios back to optimized defaults. Stock clock is now 4.3 ghz boost. While the test ran succesfully with 0 errors, my temperatures spiked to almost 100C and temperatures ranged between 90-100C. This is highly unusual. I delidded my cpu with LM and I'm using a Dark Rock Pro 4 Cooler. However I doubt my cpu runs at 100% during game and other benchmarks. Is this the problem?
