MAJOR issues with 6 month old PC

[alpine crag]

Hoping someone could help me. Yesterday, I started experiencing massive issues with my PC, particularly when gaming. It initially started on rocket league where my PC would black screen and reboot after about 5 mins of playing. I then noticed it was happening with every game I played which is making it pretty much unusable as sometimes I will get pink horizontal lines on my monitor or lots of pixelated squares. Ive also Dead GPU, or something deeper? Also experienced BSOD once. I've tried many different things such as:

Reseating RAM
Reinstalling GPU drivers
Changing power outlet
Restarting (obviously)
Trying HDMI instead of DP
Reverting windows
Checked temps (all good)
Leaving unplugged overnight
Cleaned with compressed air
Tried different monitor
Underclocked GPU
Cleared Space in SSD

Checking event viewer I seem to get 2 errors either being Kernel-power or nvlddmkm. Any help would be appreciated as I'm at my wits end with this atm. Please see a couple of examples of what's happening.

Feels heavily gpu related

Could be drivers (but you said you’ve reinstalled those). Could be worth reseating the gpu. But ultimately it could be a dying gpu

Still under warranty, would it just be a case of sending out a new GPU or would it have to be sent back to the warehouse for weeks? Will try reseating the GPU though

It would be a case of arranging for it to be sent back. However they have quite quick repair times, i believe last time i checked it was around 3-5 days

Depending on how many repairs of course, but they’ll let you know accurate figures 👍
