Hi there. I seem to be having a major issue with my computer. I had just finished building it a couple of days ago was beginning to instal the drives. However, I seem to have run into some problems. As I was installing my video card, my computer shut down, with the power switch still on. I tried to reboot it, but no matter what I did nothing worked. Now when I turn my computer on, all the fans and lights turn on for 3-4 seconds then I hear a single beep (Only when the HDD is still attached) and it turns back off. When the HDD is out, the computer does the same thing, just without the beep. I took out all my drives excluding my PSU, CPU and motherboard and tried to boot the computer again but the problem hasn't changed. At this point I have no idea what to do and need help.
Here's a list of my current specs...
