Mincecraft boots up fine. I created a world to test my graphics(i haven't played on this computer before) and when it loaded i got random white flashes, chunks were flickering, animals were flickering.

When I opened the graphics settings to change settings in order to try and fix it, the menu was flickering as well, including the graphics menu. Then it crashed.

Later, when I tried to load the world, i loaded a blue sky and that was it. It crashed. No error report, it just reopened the launcher.

The most recent time i just looked around a bit, with all the flashing and flickering, and did the F3+C force crash, so here is the report.
