ASUS 4090 bricked 2 months out of warranty (black screens, kernel crashes) This is my plan going foward.

I was recently testing out rtx super resolution and hdr on old yt music videos on my tv and i loved it but suddenly the card started giving issues and is now almost completely dead.

The symptoms are: Kernel panics, black screens, not initializing on boot

What i tried: Fresh install of windows, cmos clear(normally cant get it to output again until i clear cmos), nothing connected but the gpu and a single known good ssd, asus bios updates, old/ new drivers, nvidia bios updates, multiple monitors using display port and hdmi (bought new good cables)

I even ran wothout internet at first so it wouldnt auto download drivers.

Right now the only thing that causes my system to black screen(still running but no display output) or kernel panic is when the gpu is connected. I cant use nvidia smi because it either doesnt detect the card or it black screens / crashes before i can run any commands.

The system works fine with no gpu and using intergrated graphics. If i am using intergrated graphics and the gpu is connected and detected the system still crashes after a few minutes.

There is no bios switch on the card only a quiet/ performace toggle which doesnt seem to change the bios as it happens on both modes.

The rest of my specs: Intel 9900k

ASUS Z390 ROG Maximus XI Hero WiFi Intel LGA 1151 ATX Motherboard

Crucial Ballistix Sport LT 32GB (2 x 16GB) DDR4-3200 PC4-25600 CL16 Dual Channel

Corsair RM1000x 1000 Watts 80 Plus Gold Modular ATX Power Supply

ASUS GeForce RTX 4090 TUF Gaming RGB Overclocked Triple-Fan 24GB GDDR6X PCIe 4.0 Graphics Card TUFRTX4090O24GM

My overall plan is:

Buy new parts

Build new system with 3050

Install Windows fresh on new system

Install 3050 drivers, confirm everything stable

Use the system normally while waiting for 4090

When 4090 comes back (if not fixed send to northridgefix) — DDU in Safe Mode, shut down, swap cards, boot, install 4090 drivers, test gradually

Test 3050 in old system (check if there’s pcie problems (I am going to use the old system as a nas/ plex server/ offloading workloads)

Return 3050 if not needed for plex/ upgrade to better card for transcoding/ other power use case if 3050 can’t meet my needs.

Good plan/ any feedback please? This has been very stressful for me bc the money and time i have to act before things become completely unobtainable due to ai/ buisness practices. New cpus are launching soon which means the micro center bundles for this generation will end. I dont need anything thats coming with the new generation and its the same socket anyways so i can upgrade if needed.
