Gaming Black lines on game

[DatVietDude]

Hey guy, apparently, I hafta use a VERY VERY crappy graphic card to see anything on the computer... I tried playing any type of games but they all generate a black line on the map. Any idea how to fix it or do you know the problem?

Also, the better graphic card caught on fire right after I put it in and start up the system... Soooo, I wouldn't want roasting marshmallow using my computer even if it's nice and warm..

your graphics cards. are all either old and damaged. or they are getting damaged by the heat coming from your system. check if everything is clean, get a can of compressed air, go through all the fans. run a program like speedfan to check temps.
