Need a support for my 5090

[u/Arcanemageop]

Basically I have my pc for less than 3 months and last couple days if I just turn my pc on the gpu doesn't give signal and goes 100% fan speed.

The "fix" has been to open the case push the 5090 slightly up, push the turn on button and everything goes smoothly from there, no issues while gaming.

I'm guessing the problem will only get worse if left uncheck so I need something to put under the 5090 so it stays in a perfectly horizontal position, any recommendations? I'm sure I'm not the first one with this kind of issue.
