Hi guys
I am having worst time building my new pc. First let me tell you specs of my pc
FX6300 cpu
Gtx 750ti GPU
4gb 1600Mhz ram
Corsair vs 450

First problem I ordered gigabyte 970a ds3p motherboard, installed everything but my cpu fan rotation was not proper. It was kind of wobbling. I replaced my psu with a working local psu but same condition then I replaced cpu still same case with new cpu. Don't know what to do next.
Second problem, then I ordered another motherboard Gigabyte ga78lmt usb3. Installed just cpu and ram on motherboard but did not get any display, then installed everything else but same condition.

Third problem, with no way further I decided that I will install ram and GPU on my existing/working system (Pentium E5700 and G41MT-S2) while ram addition was successful then I uninstalled on board graphics and mounted 750ti on G41MT-S2 but then again no display.
I can hear windows loading but no display from GPU but I get display as soon as I connect vga port of monitor to motherboard I get display.

Please help me guys I am desperate and can't believe that I would get so many defective pieces and all of them brand new. I have gone through forum's cpu won't boot/no display guidelines but can't figure out what is wrong.

I tried to explain all situations in detail do that if I am doing something wrong you guys can help me.

Thanks
