Whenever I try to turn it on though, the front LED just turns on and then everything turns back of I have plugged everything in and triple checked it and my friend who knows a lot about PCs checked it too.

You can just edit the old post, and install the CPU cooler, it wont boot without it

[Mr.Meerkat]

Install your god damn (sorry for the profanity) CPU cooler...it's probably either not detecting a CPU fan or it's thermal shutdown.

you dont have a CPU cooler on and you are wondering why it wont boot?

Sorry for the confusion, I have the stock cooler on .
