Ok so I was building a PC for my parents about a year ago, set up everything how I thought it had to be done and... nothing. It didn't work. I tried troubleshooting it (with the help of you fine folks) back then but had no joy and I had to go back to Uni which meant leaving it for a year. I'm now back trying to get this hunk-a-junk to work. And I REALLY need some help 
Specs of the build are:
1 x Asrock FM2A75M-DGS A75 Socket FM2 VGA DVI 5.1 Channel Audio mATX Motherboard
1 x AMD A10 5800K Black Edition 3.8GHz Socket FM2 4MB L2 Cache
1 x Corsair Vengeance 8GB (2x4GB) DDR3 1600Mhz CL9 1.5V Non-ECC Unbuffered
1 x Crucial 64GB M4 SSD - 2.5" SATA-III
1 x Seagate 1TB Barracuda 3.5" SATA-III Hard Drive - 7200RPM
1 x Microsoft Windows 7 Home Premium w/SP1 (not yet installed)
1 x Powercool 450W PSU - 4x SATA 1x PCI-E
When I turn the power on all the fans (CPU and power unit) whirl up and it seems from the outside to be working. But it isn't outputting anything (as far as I can tell).
If I remove the RAM it beeps 3 times, stops briefly and repeats (which I believe is a goodish thing as I think that's it detecting missing RAM). But if I boot up without a keyboard or mouse plugged in it doesn't make a sound (might not be an issue, but I'm used to PCs issuing a long beep when it tries to boot without a keyboard).
I'm willing to try darn near anything and will provide any information or pictures or anything people might need. (I work during the week so any attempts at fixing will be done over the weekends, but I'll be sure to keep an eye on the thread).
I know you guys have tried once before, but I'm hoping you'll be kind enough to lend a rookie a hand again and maybe get this PC doing what it's meant to!
