Initially, when I installed a block on my GPU and didn<|pad|>'spaid attention to VRAM controllers, the connection was short-circuited. The GPU stopped working and the PCIe slot got damaged. Although the Z790 form factor motherboard shows no visible damage, it won't run with a new GPU. I recently got a new GPU that doesn’t work on the faulty motherboard, so I’m replacing the motherboard now. It looks like I tried my new GPU on the broken board, and I’m worried it might be broken. Could testing it on a new motherboard cause further issues?

This makes very little sense. Not putting pads on it should not cause a short circuit and frying the PCIE slot. It would just get hot eventually. Unless you have a bridged connection somewhere, it shouldnt really do that due to the spec of the block. there should be enough of a gap for where the pad has to be. Did you use liquid metal? did it spill onto the gpu? What block and GPU did you use?

I started with a metal GPU but covered all resistors with thermal grease. It wasn't my first experience with liquid metal. The board was a heat sink killer because I left the red support tabs out. When I powered it on for the first time, it worked well; the next run failed. Now I have a new GPU and didn<|pad|>'s been careful. It still draws power level D6, so it can't be the GPU itself. The issue seems linked to the motherboard. After troubleshooting the 4090 TUF OC, some liquid spilled on it but I cleaned it thoroughly with IPA and did a visual check. No burn was seen. The PSU looks good, it's 1600W Prime ATX, the CPU is fine at 14900k, and RAM is 96GB DDR5 Platinum. Feel free to share onboard graphics.
