Hello yall,
today I'd like to seek your opinion on a peculiar issue I've been having, with rather painfull hit as of late.
For a while I've been having an issue with my old gpu GV-N108TAORUSX W-11GD being random screen going black no signal plus fans starting to spin at 100% and having to manually hit reset to do anything.
I've seen it a 1000 times and experienced it around 10 throughout all my rigs so just assumed it's the gpu dying. One time after such event and usual reset I encountered black screen with "please power down and connect the pcie power cable for this graphics card" which was new. Again assumed that's just next stage of death and with tears in my eyes bought the succesor GV-N308TGAMING OC-12GD.

Life was good for almost year after that, enjoyed the improved performance and even started to think about buying better refresh rate monitor then my 60hz Iiyama. When I found some spare time and money I decided to attemt a fix on the old gpu, so many years together and all plus while it might no have rtx it still was a great performancewise gpu capable of easily running anything at mex sets in full hd. Since it seemed problem was deeper then just dusting off and replacing thermal pads and paste I sent it to pc hardware wokrhop specializing in gpu restoration.
People there however soon contacted me and said they checked the gpu through and through and there is simply nothing wrong with it. I was quite suprised at first but shrugged it off to either luck or maybe they made a mistake or didn't check deep enough.

More time passed and since last week I started having same sudden strokes into black screen with max fans but with my new gpu this time. Yesterday evening had another such case, I was pretty mad due to this happening in the middle of Elden Ring boss fight, so instead of restarting I shut the rig down and went to cool off. When I got back however rig wouldn't power on no matter what I did. I went to sleep thinking "it's too late for this cr@p, I'll handle it tomorrow".

Well it didn't go well. Rig turns on, both motherboard and gpu lights on, fans spinning, no beep, no errors just black screen with no signal. I pulled the gpu out, noticed that despite being just powered on for few mintes not doing anything the backplate was incredibly hot. I swapped back the old 1080TI, same pci-e slot, nothing changed in other hardware, it runs fine. Meanwhile 3080TI seems to be dead, or in zombie mode considering no display but spins fans and flashes leds.

Do yall think that's just a strange coincidance or maybe I should investigate possible culprits in either motherboard or psu? As far as I know these are the only two things coming to my head that could somehow do this.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard?

To me it seems like your PSU might be at fault or the power connection to the GPU might not be secure.

My apologies and thank you for your interest, Here are the details:

CPU: i7-8700K + Arctic Freezer 34 esport duo
Motherboard: MSI Z370 Godlike Gaming
BIOS: E7A98IMS.AB0
Ram: 32gb Corsair Dominator Platinum CMD32GX4M4B2400C10
SSD: 240gb Patriot MP500 + 1tb Samsung 970 Evo Plus
HDD: 5tb Seagate ST5000DM000 + 3tb Seagate ST3000DM001
GPU: Gigabyte 1080TI GV-N108TAORUSX W-11GD / Gigabyte 3080TI GV-N308TGAMING OC-12GD
PSU: 1,2kw Seasonic Prime Gold SSR-1200GD
Chassis: Cooler Master Storm Trooper SGC-5000-KWN1
OS: Windows 10 Pro v22H2 build 19045.3324
Monitor: iiyama G-MASTER Gold Phoenix GB2888UHSU-B1 28"

Not sure about precise age of the psu, I dug up the invoice for it from 12.18.2017 so I'd say it's at least 5-6 years old. Damn like I said I did suspect either it of motherboard but I had hoped for the latter.
Decent used one (since only new ones for socket 1151 at this point are 2 ram slots, micro atx pellets) I could grab for a 100$ more or less. Psu on the other hand I'd not trust even close friend to buy used from so will probably fetch twice that or even thrice/quadruple if I'd want to feel safer and up the standard to platinum or titanium.
