Having some issues with my system (built last Friday)
i7 4770k
Maximus VI Formula
Sandisk 480 SSD
16 GB 2400 Ram (@2133 currently)
Gigabyte R9 290X video card
Corsair AX860i PSU

I go into the bios, change the setting from Default (Auto, igpu, PCI-e) hit save and every couple of times it'll start, then shut down, then start back up again that's when it's taking the PCIE card.

When it doesn't shut down after I make the change I know it's just MB graphics. Installed all drivers, still get it going for a few then it craps out again. Not sure if it's the board not taking the bios change, or the card is defective. I got it going Saturday and it ran thru Sunday, today I go to put a CD in the drive and the screen goes black and I have the Video card out again.

Help!
 
Solution
The PSU power connectors need to be hooked up to the GPU, in order to be recognized correctly. Your PSU should be overkill for your needs, so it normally shouldn't be a problem. I would just double check that you plugged into the PSU correctly and are also using the PCI-e power connectors on the GPU (you can use the wrong ones and also plug into the wrong ports on the PSU, not saying you have, but I'd double check it).

Thanks for the quick reply!

Tried that, swapped both sticks, still nothing. Just have the CPU, SSD and RAM. I put the other back in and apart from the card everything is running great.

When I changed it in BIOS (and it took) the comp started, seemed to shut down like it switched, then fired up with the video card working. Now when I change it in BIOS it just stays with on board video, no "switching". I've tried new power cables to the card, switched out which it's plugged into (modular PSU), nothing.
 
Hmm, my first thought is that your Mobo has an issue. Normally most people can just put the dGPU into the PCI-e slot and hook up the power PCI-e connectors from the PSU and your good to go. Sometimes you have to select the GPU that your going to use in the mobo BIOS, but that is usually on older mobo's.

Now it's entirely possible that the PSU isn't powering the GPU correctly, but I'm not 100% sure about that.

Did you run Memtest86 on each of your RAM sticks?

Thanks, I'll try it when I get home (at work now).

Do you know if the card would be recognized if plugged into the mobo even without the power cables attached, or do the 8 and 6 connectors have to be on the board to even have it recognized? I'm just wondering if the card should have any kind of "pass through" from mobo to monitor as long as it's physically attached to the mobo regardless of power. I was kind of worried about my PSU, I've never had a card that needed extra cables attached, but I thought 860w would be enough when I bought it.

I got it sorted out finally. I ran Memtest86 and the RAM was good. So I tried updating my chipset drivers and update my BIOS. Nothing. At that point I gave up and ran it down to Fry's Electronics. I knew it was hardware and without parts to swap I couldn't get anywhere. The tech checked it out and thankfully it was just the video card (I really didn't want to rip my mobo out....). I was able to pick up an Asus R9 290X there; all credit cards maxed out now until I RMA it but WTF....

I want to personally thank you for taking the time to help. I'm certain that if we had kept at it you would have figured it out. I haven't built a comp in over 10 years so I'm a noob with modern components. To have a stranger take time out of their day and give someone else a hand proves that humanity has hope, the net isn't just filled with trolls and haters.

Again, the service you do for guys like me is incredible. Kudos man!
 
Your very welcome. We have all been in your shoes at one point or another and I appreciate the praise. I work hard to try and help the best that I can and is sometimes very hard to do over the internet without seeing the system with my own eyes.
