Hi,

I just built my first computer and unfortunately it doesn't work. Everything starts, fans, mobo, cpu fan. I first put the cable on the GPU wrong so it was a red light. I fixed it so now it's a yellow-ish light instead. The screen is black though. Is it because I haven't updated bios to support the 3600? If so, how do I upgrade it without a screen? I also don't have any OS installed on it.

Thanks
 
Solution
I've never seen a yellow light on a GPU, should be green. I would double check those power supply connections to make sure they are all good.
