Hey all you people out in the interwebs, I've been watching these forums for a while now but have not really had a reason to join until now. I need some help. Namely, with the graphics. Up until recently, my dad has used the computer my MC is running on. He then gave it to me for me to rebuild for personal use. However, ever since the rebuild, the graphics slowly got worse. Here is what happened: I got on, and it would be fine. At some point, small outcroppings in the ground would appear. A few days later, small animated fire clips and portal clips would appear with pieces of what appeared to be an original texture pack. Days passed. This escalated until I could not see the screen. It never crashed. I searched around the support forums, but nothing seemed to help. I then went to the trusty Google. I found that a similar-ish problem happened. They solved the problem by re-installing the graphics drivers for the graphics card. I did this, likewise. Here comes the weird part. I reinstalled the driver, and everything went back to normal, but a few days later, everything started back from the beginning, and the small outcropping appeared. This continued. I decided against playing Minecraft, and have not played for a month or so. I let it be. Then, out of the blue, small bars appeared on Google chrome. Little pixel bars, appearing whenever script is being used. I did some research again, this time finding that the problem is that the graphics card is artifacting. This did not give any solutions to the problem, however. Now I turn to you. I don't know where else to go. Should I get a new card? Is there an immediate fix? I have hundreds of pictures/screenshots of this if you want them. Sorry the post is so long I just really need help because I am pretty lost right about now. I use 1.7.5 MC, and have an NVidia GeForce 7600 GT graphics card. I can supply any details if you like. Thanks!
