[Patch]

34 is disabled PCIE switchy, GPU cold boot bug, no power to card (when I forget to plug it in) or simply poor contact. Vaseline won't cause your trouble - my slots always have giz. Look for some slimy eraser or an insulation crumb in the slot.

Most of the time I get that problem it's because the card is tilted down a little in the back from fiddling with something and the front of the card lifts up out of the slot a tad and loses contact.
