Graphics card fails when standing computer upright, works on it's side.

[poarchct]

My graphics will fail when I stand my computer up. Laying on it's side is fine, but as soon as I stand it up it will crash to a black screen and my monitor will read "NO SIGNAL" I know this is likely due to graphics card sag. I have also switched PCI ports and the problem persists. Any ideas?
