Random Blue Screen and Now I Can't Even Load Into My BIOS

[Kitty Claws]

I just built my first PC and lots of things have been going wrong. I've been able to fix them mostly but now I don't know what to do. While installing Planetside 2 from the daybreak menu my computer blue screened. Whenever I turn it on it boots for a couple seconds and turns back off and goes into a cycle of doing the same thing. I can't get into my BIOS and I can't load from a winodws 7 disk. I've checked to see if it had to do with my RAM but that didn't seem to be the case. It was working fine this morning and last night and I'm frustrated beyond the healthy limits. I wasn't able to get a picture of the bluescreen and no messages pop up when starting my computer. Please help.

Side note: I discovered last night that three out of the six usb drives connected to the motherboard were dead. Which is why I'm leaning towards a faulty motherboard (just want some reassurance).

If you are blue-screening it means you posted and ran into errors within Windows.
