Hello everyone,

I have got a problem with my Hackintosh I bough last month on Ebay. It was brand new, build on request with all the parts because I am a totally newbie into building Hackintoshes. It worked perfectly fine until two days ago, I got back from my University, wanted to turn it on, it got past the Gigabyte loading screen and Maverics and then when it gets to Apple logo, it loads for a bit and then freezes and spinning wheel stops. I tried rebooting it quite a lot of times and quite often it doesn't even send any information to my computer screen, which starts looking for input and then displays error that no cable is connected, but I can still hear the computer working. I was looking for solution online, but I didn't found one. Please notice, I am complete newbie, I haven't build it I got it made and got no idea what happened to it.

Specs:

OS X 10.9 Mavericks
Intel Core I7 Quad Core 3.4GHZ 3770
Gigabyte Ultra Durable GA-Z87M-D3H or GA-H87M-D3H (Guy just told me it is a Gigabyte motherboard and he included an user manual in the box, which is for both of those)
16GB Corsiar RAM
1TB Seagate HDD


Thanks in advance for any replays,
Dan
