Question / Help NVENC encoder using 99% of my GPU Encoder overloaded issue

Hello, so recently I just had my PC taken to a store to get it watercooling. Once I brought my PC back, I wasn't able to record anything in OBS without having my framerate drop to 3fps. I don't record with the x264 encoder because it's CPU based, however I have tried but using this only uses my CPU. For some reason my NVENC is making my GPU load 99% if not 100%. It also comes up with the message saying; encoder overloaded! Consider turning down video settings or using a faster encoding preset. I've tried everything, from re-installing OBS, downgrading windows, upgrading windows, upgrading drivers, changing all my settings in OBS. My temperatures are fine, and there is no overheating. As I said, there are no issues other than when I record.

My SPECS:
CPU: Core i7 7700k
GPU: Gigabyte Geforce GTX 1060 6GB (NVidia)
RAM: 16GB DDR4
MB: ASUS Prime Z270-AR
Case: NZXT H500i
PS: Corsair 500W PS
- not sure about watercooling but it's not a full loop, just CPU watercooling.
A more than capable build, right?

My GPU is working fine with running games and everything on my desktop, there are no problems there. The only issue is when I record. I usually record games such as Fortnite, CSGO and occasionally Minecraft. I was able to record Minecraft at 360FPS Fractional framerate before this issue started, and now I can barely even record in 60FPS. I'd really appreciate it if someone could help me out with my issue.

Attached below are some screenshots of my usual settings that worked perfectly fine. Note in the 2nd link I have the FPS numberator to 240FPS because I was recording Minecraft.

I'd really be grateful if someone could help me with my issue, thanks. :D

What did you change recently? Because OBS hans't changed for a while now, so something else has changed.
Either way post a log from a recording session.

Fire up gpu-z and post a screenshot of the first tab. May be your GPU card isn't running in x16 pci-e bus mode after the hardware change.

I haven't changed anything recently, however I had a bluescreen of death pop up because of an application my friend and I were designing and I'm not sure if that did anything because I've had a bsod before I took my PC for watercooling and OBS worked perfectly fine back then. Here are my log files.

I'm pretty sure it is running at x16 however here's the ss.

Yeah, it's not running @ 16x, but at 1x. Make sure the GPU is in the slot closest to the cpu and seated properly.

It's in the right slot, sitting in there pretty securely. I just took it out put it back in and it's still on 1x.

To make it totally clear what Osiris said: the slot marked with the blue 2, which is labeled "PCIEX16_1" and which is located nearest to the CPU. The other wide slots are only used for GPU cards in SLI setups where you plug in multiple GPU cards. If a single card is placed in one of the other slots instead of PCIEX16_1, it is running with x1 speed instead of x16.

Thank you so much, I sorted it out. :D

Sorry to re-post about this again, but my GPU switched back to 1x. Before that, the way I fixed it was by removing my GPU and then putting it back in place again as it was already in the top slot. I don't understand why it's gone back to 1x speed instead of x16.

Except it won't.

The pci-e lane count is negotiated at boot and does not change just because you're trying to run load on it.
