Hey everybody
Just threw together a new computer

Motherboard: MSI FM2-A75MA-E35
CPU: AMD Athlon II X4 750K
GPU: Nvidia GTX 220
PSU: Seasonic S12 (520W)
HDD: Can't remember the name but it's working fine, just threw it back into the computer I'm typing this from and it's all good.

But nothing happens when I have it all turned on. It comes on, runs fine, stays on, fans are spinning, HDD spins, DVD drive works fine, everythings all plugged in but the screen is just totally dark, nothing happens. Yes I've gone through that checklist numerous times, and no, none of it helped. Any suggestions would be greatly appreciated.

Thanks,
Kyle

Yeah, when I first tried turning it on I hadn't even put the video card in it yet.

Honestly, at this point, I'm just wondering what I should request an RMA for. Since the Hard Drives and DVD drives, fans, and LEDs are running it probably wouldn't be the PSU right? And I know the GPU and disk drives works because they both came from existing computers but I don't really have the means to test the CPU or mobo or RAM out because I don't have any compatible parts.

I have seen this problem on my computer as well. It won't turn on. I found that if I unplug the power cord from the back of the computer and the wall and then plug it back in it works. I believe that there is residual electricity in the cord that is causing it to bottleneck. You will probably have to get a new power cord to completely get rid of the problem.

Have you tried a new monitor? Or can you hook it up to a known working source? Something else you may consider is the motherboard. My girlfriends laptop had a similar problem where everything would appear to be working, but nothing would come up on screen. It turned out to be the motherboard. Its rare to get a DOA part like that, but it happens.
