Ok, so I'm building a PC of course and its currently external and I have everything supposedly required hooked up. But, when I turn it on, all fans run (the CPU stock fan runs for a bit, then pauses, then runs again) and then I get the 1 long, 3 short bleep and no display on the monitor. I have tried using a single RAM card in various places and have switched the GPU around to the other PCI Express slots. I'm hoping that its not a compatibility issue with the graphics card or the CPU has been munted because its now firmly concreted in place with thermal paste that was on the stock CPU fan. I have browsed the manual and there is nothing in the troubleshooting section about the bleeps I heard. I have a:
Gigabyte GA-970A-D3P motherboard,
Kingston Hyper X Blu 8 GB (2x4GB Modules) 1600MHz DDR3 memory,
AMD FD8320FRHKBOX FX-8320 FX-Series 8-Core Black Edition
and here's where I think it gets a little sketchy, HIS R9 280 IceQ OC 3GB Graphics Cards H280QC3G2M and a PSU I bought from one of my mates which is a case stock PSU for an Aywun A1-923 ATX case 500 Watt, but according to PCPartPicker my build is under 450 Watts.
Any advice will be greatly appreciated
