I also ran into invisible walls and fell into a gaping hole on my pc, this though was when I owned a GT520 graphics card, I was tired of bumping into invisible rocks it was like the world was trying to catch up to me running.

So I went and bought a brand new Power supply unit and a GTX 650 graphics card and all those things disappeared.

Best thing you could do is save up, buy yourself a playstation 4 or get a brand new pc, if its a bit stuff on wallet, go playstation 4 route and just exchange some games for credit.
