Every time I play on Hexxit, Tekkit, and now Hack/Mine, (I haven't tried any of the other packs yet) I can play for a maximum of 10 minutes. After 1-10 minutes, the page goes 100% white and the game crashes. Most times there isn't even a crash report. This has gone on for 2-3 days now (I think) and I have no idea what is going on. Every time I want to load a mod pack, I refresh my laptop. When I first downloaded Technic, I could play it for maybe even an hour without crashing. Please help! P.S... if your still reading this long post your awesome! (Btw, I don't have a crash report)

Hexxit can stay open for about 5-7 minutes on my laptop, but then the screen freezes, I can't move my mouse, and suddenly the whole game screen goes white, then it says 'Hexxit has stopped responding, but it has fully recovered.' There is no crash report, and this happens every time I try to run hexxit or tekkit. When I first downloaded technic, hexxit ran for about 10-20 minutes and then crashed.I don't know what happened. Please help!
