OK, so I'm having this problem. Ill be playing minecraft for a while and at completely random time it will just black screen me or shut off the whole process. When i get back on the data i had will be unsaved... is there any way to fix this?
P.S I have no mods installed but i do have a few texture packs i use.
If the texture is HD then you may be using up all of java's allotted memory. To fix this change the heap size to whatever your computer can afford. Max for 32 bit is 1gb which is the most common version of java. Look up a video of how to do this.
