The first thing to do with that computer is to get a new power supply - Raidmax is one of the worst brands out there for power supplies.

Yeah I plan on getting a new one as soon as I get some more money, but do you think the power supply is causing this or is it because I did something wrong?

According to http://forum-en.msi.com/faq/article/power-requirements-for-graphics-cards a 6850 requires 25 amps on the +12V rail, but according to the Newegg specs, your psu can only deliver 22 amps (28 according to the sticker in the images), but I wouldn't be surprised if the effective limit is actually lower. I hope you haven't already fried your other components.
