Green dots, crashing, and blinking lines.

Hey everyone I could use some help.

I just got my Alienware Aurora yesterday and my first startup was really messed up. I mean i had all these lines going across my screen and then it crashed. I rebooted it again and it started up but.... There were some green dots all over the screen... Since then i've downloaded a ton of different ATI Catalyst systems and none of them fixed the problem. I tried a new BIOS (the 0.9) that didn't help. I even unplugged and re-plugged in my graphics cards. I have no idea what to do. Also you know how you press the alienhead to uncover the drives? Well that cover only goes down about 1 inch and then stops when I press the button. My main concern is the crashing and dots, I would like to fix the cover tho... Thanks (It  has crashed many times since the first crash also)
