Could someone double check my parts compatiblity

[ujalu]

I made a thread a couple of days ago and didn't get much response so I'm hoping this one goes better. Old thread with more info on problem http://www.tomshardware.co.uk/forum/forum2.php?config=tomshardwareuk.inc&cat=13&post=280628&page=1&p=1&sondage=0&owntopic=1&trash=0&trash_post=0&print=0&numreponse=0&quote_only=0&new=0&nojs=0 .
When I turn on my computer all the fan turn on but I'm not getting any video and I don't hear windows start up. I also have to turn my power supply off to turn the system off. I have also tried using a different video card without any luck.

parts
CPU: AMD Athlon II X4 630 Propus 2.8GHz Quad-Core AM3 95W
motherboard: GIGABYTE GA-MA770T-UD3P: Socket AM3, AMD 770 Chipset, ATX
RAM: G.SKILL 4GB (2 x 2GB) 1.5V DDR3 1600 Dual Channel
video card: Radeon HD 5770 1GB 128-bit GDDR5 DirectX 11
PSU: Corsair CX400W PSU
harddrive, dvd drive, case: don't know, using parts from old/broken computer

I think that it might be the memory, I don't see it as compatible on my motherboards website. I picked the parts from an online suggested hardware guide so I had hoped that they would have checked the compatibility.
