Crashing Drivers?

Yesterday, my videocard started acting funny, or my drivers anyway, my videocard seems to run fine.

i was playing modded minecraft. just two mods, shaders, and optifine. but yesterday or the day before yesterday, some time around there minecraft started just crashing every time i try to open it, and when it crashed, it took my drivers with it. i have to underclock my gpu (XFX R7950) down to 800mhz for it not to crash. but when i play any other game, ex: battlefield 4/3 metro last light, fallout, or any other game in my library it is just fine when at 1105 mhz

core clock. 

 

any idea what is going  on there?

 

edit: i've been playing with those two mods for about a month now, and it has barely started doing that this week.

 

Drivers: 14.1 with the minecraft fix.

Did you see if it works with the stable drivers (13.12)

yeah, it sitll has the same problem. even if i run minecraft without any mods.
