Hello, Ive been having troubles with ether mine craft or World of Minecraft, not exactly sure which. before you say there are many topics such as this, ill let you know Ive looked literally everywhere online for a resolution for this issue. my problem is that when i go on multi player and even single player my computer crashes completely after about 10 min, i can't press ctrl alt del it just literally freezes on a black screen, thus it results in me having to turn off the computer and restarting. people told me i should lower the rendering distance ect, which i did on single player. Ive also deleted everything related to mine craft on my computer (%appdata% ect) and reinstalled it back again, but still the same thing happens, sometimes i even get a white screen with black lines going vertically. also my java is up to date. I'm seriously hopeless i cant find any resolution to my problem, if anyone could please help me out i would be very greatful. thank you very much!

P.s i forgot to mention, i dont get any error messages, whitch is why im stuck as well...
