Every day my first game of the day crashes and my graphics card crashes.

First game of the day, I que up, do the champ select, timer runs to 0, my screen turns black and I cant do anything. I boot my laptop and after that everything works fine until I stop for the day and turn off my laptop. next day it happens again. This started 3 or 4 patches ago, before that the game worked just fine. Every other game I play works fine so it shouldn't be the laptop breaking down. halp.

also, the bug report button in client throws me to the "REPORT A BUG" page, which seems to not work, "We encountered an error while trying to process your bug report. Please try again in a moment" ->multiple days in a row.

Laptop: Dell Precision M4500
