minecraft problem please help
 |  |  |
I have a new HP Pavilion dv6 with windows hp,
8 gb ram ,
1 terra memory
AMD A6 QUAD CORE PROCESSOR
I have Minecraft for 9 Months at first it worked perfectly, but for some time i didn't play ,and when i started Minecraft, every object looked separated (EX: every block of water was separated by a white line from the others , and i can see those white lines in the dark) , it's really annoying , besides, in the distance the water is pink .
I don't know what to do, it looks the same on every texture pack , and i've tried everithing
but nothing works ,i even installed an older version, (i have 1.2.5) but nothing worked.
Please help me if you can , i am new here.
