Zotac Trinity OC RTX 3090 - very strange symptoms, suspected vram issue. Most of the time shows vga light on boot but sometimes boots up into windows and has ran on a benchmark for over an hour with no issues. Abrupt crashes to a black screen happen under some other loads and event viewer lists the crash having something to do with the video drivers. Has been repasted recently and cleaned up, which was what allowed it to boot up at all, but didn't completely fix the issue.
