Solved Is my GPU dying

Recently for the past week or so my PC has been crashing games to desktop but only recent ones (Starfield, Remnant 2, Everspace 2, etc.). I can play games like Everspace or FC3 just fine but as soon as I try any of my new library they crash in a min or couple of seconds. The UE games show a 'DXGIERROR_ DEVICE HUNG' in the crash logs and with task manager open I can see the GPU spikes from like 30% usage to 100% during the freeze and subsequent crash. I looked online and apparently this is TDR or smth but does that mean that my GPU is dying?

I've removed the RAM and GPU, blown them off and reseated and everything is secure and plugged in. If it helps i recently upgraded my PSU, mobo and CPU, so my RAM and GPU is from my previous setup but it worked just fine there and I didn't drop or bend or otherwise damage them when moving over. Everything was working fine until last week when Starfield started crashing only a few seconds in game. looked it up and apparently it was an issue with the new update so I gave up but noted in the crash logs it referenced issues with the GPU too. I only really connected the two when Remnant and Everspace 2 crash within a minute of booting up (I can't even make a character in the former) and HSR now is freezing and crashing too despite working completely fine before. Now the PC is freezing as well a min or so after the game crashes.

Is there anything I can do or try? I don't have a spare graphics card to try and see if the RAM is acting up and my PSU is 850W so there should be more than enough power left over. I'm not overlocking GPU or CPU and its not factory overclocked. I have XMP turned on and Windows and GPU drivers are up to date. I can't think of anything else that might be relevant but if you need anything else please on. I'm at my wits end, I just wanna play silly games on my really expensive piece of silicon.

The PSU is a corsair RM850x and here is the file, I saw that it might be failing RAM so I removed 16gb of older RAM and have been trying that. Sorry for the late response, my windows corrupted and I had to reinstall my OS

I'm using slots A2 and B2, and both RAM pairs are Corsair LPX Vengance 16gb (2x8) 3000 DDR4 but the new ones i bought say on the back ver 5.32 or smth and the old ones are ver 4.smth. I was looking around and apparently my mobo (Z690) has issues with XMP causing crashing so is there a thread for me to follow as a noob to properly set it up? And how should I go about installing those drivers?
edit: The pc seems more stable with just the two new RAM sticks but still does the GPU hang crashes, and I forgot to mention but apparent XMP plays up with the NVME as well? Both times my OS corrupted this week I had installed it on the NVME (970 evo plus)

I downloaded the intel driver support tool and it says I have upto date chipset drivers already and i did already install the GPU drivers so hopefully that wont cause an issue, are the SATA drivers included with the chipset or what the intel tool checks for?

Right so once I save them from a flash drive what do I do then? This isnt bios flashing is it? Do i like run them off the USB or else? Sorry Ive never done this before

Hi I had work this weekend so I wasn't able to do much but I saw that underclocking the GPU can fix nvlddmkm errors and lo and behold it did, so far the games that would crash in a min or so have run fine for more than 10 mins and whereas benchmarking was crashing now it is running well. Does the fact that I need to underclock to fix this issue indicate the card is dying? I never had to on my previous and as I said before, I even upgraded PSU
