I have pvp mods like Reis mini map mod, battys coords mod, armour status, potion status, etc, and my minecraft keeps blackscreening but I can hear whats happening i just get a black screen, when im not using forge this problem does not occur, is it something wrong with my mods? Please help. It has not always done this and just started. I also have 12 gigs of ram into minecraft so nothing to do with not enough memory. Please someone help.
