Hi, I just bought a EVGA 4 GB GeForce GTX 960, AMD FX 6300, and MSI 970 Gaming Motherboard. I already had a case a 525 w powersupply, SSD drice, Hard Disk Drive, 8 GB RAM, so on so forth. I put the computer together, plugged everything in without graphics and it booted fine (no graphics at all, so not sure if there were any errors on screen, but no beeps or anything). Then I installed the Graphics card, which required an 8-pin connection, I used the included 2-6pin to 8pin adapter and booted it up. There was no output. fans stuttered and seemed to try to get going but didnt really go at all, the seemed to flicker every few seconds. what is wrong why won't it boot up, it's brand new?
