Two questions, when I open maya 6.5 on my computer the little bar in the lower left corner says "Warning: Unable to start docServer." Whats causing this? It doesn't happen when I open maya 8.5

Next question, all my geometry gets this weird see through in both 6.5 and 8.5 it's hard to explain so I'll attach an image. Is this the cause of a weak graphics card? I'm guessing it is, but this is a recent issue I've been having since I reinstalled 6.5 but it's always happened in 8.5.

Thats how my geometry looks in both versions of maya I have on my computer. before I ever installed 8.5 I never had this glitch but now it's happening in both versions out of no where. I'm thinking a better graphics card would fix it. I really want to work in maya again but that glitch is really irritating to try and deal with and to work smoothly.
