I am not sure where this would go. It can actually fit into a few categories I think. Here goes! My son is building a gaming computer as a gift from me for his B-day almost 2 years ago now. He already had a pc so basically he is making it better, a lot better. He needed only a few items. I bought the items he wanted that he said to buy and would be compatible with his computer and the other parts bought. All parts were bought by Newegg.com. Like I said this project began about a year and a half ago and we still cannot get his pc up and running. No one seems to know what the issue is including his father who use to put computers together. Can you please help us? Please tell me if what parts I bought and what he already has are compatible or not? And also, his question is, is the Motherboard 100% compatible with the video card? If not, what do I need to get? If they are compatible or should be, what do you think the problem may be? Please, please, help us! I will begin by giving you a list below of what his computer already has. Then I will give you a second list of what I bought for it.
Now I will tell you what happened when he tried putting it altogether. Troubles seem to begin from the beginning when the video card wouldn't work. Which was the very first item we bought. It worked in his fathers computer just fine. The only thing different his father claimed was that he had a better power supply than him. So we bought a better power supply. It didn't work. So he thought that maybe the power supply still wasn't good enough or compatible so I then bought an even better power supply. This one all his friends have working in their pc's with no problems. Their computer's hardware and software and by son's are nearly the same. The first power supply I guess did nothing. When he got the second one it powered up unlike the last but does not display video. So, we are back at not knowing why. His question is again, is his motherboard 100% compatible with the graphics card/video card? We also bought a motherboard at some point trying to fix it. Are all these items compatible? Everything was bought to be compatible with this video card he wanted. Both power supply's worked in his fathers computer fine. So did the video card. I spent a lot of money and their are no returns. Please help. My son is past discouraged about all this and now quite depressed over it. And I am going broke! LOL Seriously though!


List #1
1.) He has a windows 7 operating system
2.) 12 gigs of RAM
3.) Processor PPG is Intel I7 4770 Not sure if K or not (sorry, if I am writing that wrong.
4.) Main harddrive is 1 tarabyte
5.) Second harddrive is 2 tarabytes


List #2 What we bought (Sorry for the long write out of it. I don't know what to write and what not to)


1.) Gigabyte GeForce GTX 970 GV-N970WF30C-4GD 256-Bit GDDR5 PCI Express 3.0 HDCP Ready G-SYNC Support Video card


2.) ASUS Z97-A LGA 1150 Intel Z97 HDMI SATA 6 Gb/s USB 3.0 ATX Intel Motherboard


3.) (The first Power Supply bought) CORSAIR CX series CX600W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply


4.) (Second Power Supply) CORSAIR CX series CX 750M 750W ATX 12V v.2.3 80 PLUS BRONZE Certified Modular Active PFC Power supply New 4th Gen. CPU Certified


5.) (Probably not important) NZXT Phantom 410 Series CA-PH410-B3 Black/orange steel/Plastic ATX Mid Tower Orange Trim Computer case


O.K. that's it! Am I missing anything that you need to know? I hope you all can help! Thanks in advance so much!

There shouldn't be any problem with that mobo/gpu working together. It's actually one of the more common setups and I myself have a Z97-A with a GTX 970 that runs with no problems. Either of the 2 power supplies you bought should've worked fine as well, other than being a less desirable make/model. Either you have a dead part somewhere or something isn't hooked up right. If you can't get it to come on I'd start by tearing it down and re assembling everything to rule out something being grounded or not in the right place. Then you can start to try and narrow down the bad part if there's one.

Hi eascusa,

We will certainly try to help you pinpoint the problem. First of all, might be a good idea to edit and remove your e-mail from the above post, we'll be able to help you from this forum and it's typically not a good idea to post that in a public forum, even this one.

To Simplify your list:

Case: NZXT Phantom 410
Motherboard: ASUS Z97-A LGA 1150 Intel Z97
CPU: Intel Core i7-4770 (LG1150)
RAM: Unknown 12 gigs of RAM
OS: Windows 7
GPU: Gigabyte GeForce GTX 970
PSU: Corsair CX series CX 750M 750W

To start answering your questions:

- Yes, your graphics card, CPU, and motherboard are all compatible.

- If your PC now has power but isn't booting then it might be your RAM. Motherboards require a specific type of RAM to work, and 12GB is not a common amount to have at any given time. Could you tell us what type of RAM you have?

- Another thing to check is to make sure that your video cable running from your monitor to the back of the PC is plugged into the correct video port. It should be going into the port on the back of the video card, not the video port on the motherboard.

-Another red flag is the type of power supply you have chosen. The Corsair CX series is notorious for having bad components. After already getting a second PSU I'm sure that is the last thing you want to hear, but even if your newer model does supply power (like it seems to be doing now) you'll want to keep an eye on it.

Hi thank you for your post. The problem is though that everything that that I bought works on the other computer in the house. So that leads to what you said about the other parts on his original set up perhaps not working. Except everything is working as it should. He is on his computer right now playing games with his friends on the old set up nothing different. Nothing is amiss. Could their still be a problem with one of his parts on the original set up that he doesn't even know or can tell? One person on another forum I think mentioned trying the video card in two other different slots which my son said he never tried. My son then said that wouldn't have anything to do with it. What do you think? Also, he say's he is going to try the slot think but the problem for him is, is that he has to stop playing, take the old parts out, swap them, see if they work, and then when they don't take them back out, old ones in and then the part he hates, he has to refigure or whatever everything. I told him that's what sucks about trouble shooting but you have to try all these little things that people suggest if you want the darn thing to work.

I just realized that I have to say who it is I am talking back to. I thought it automatically did that under their post.
This is to gramdringfh: Thanks for letting me know about the e-mail. now I just have to figure out how to take it out because I dont see a edit button. Thanks for the post and I will get back to you on how much RAM he has. Thanks for the heads up with the power supply.

O.K. this is to everyone who answered me with a post. And thank you by the way. I just talked to my son and he wants to add some important info so you will know exactly how the pc it is behaving when putting in the video card which will be very helpful.
He said that using the second power supply(because the first one it didn't even boot) I bought the pc will boot up just fine, fans run and everything. But the motherboard does not detect the video/graphics card and so then it will automatically switch over to the on board graphics. I hope this helps in determining what is wrong. And I got rid of my e-mail address from the first post.

As theonerm2 stated, we need to know if the on board graphics works and you can see a normal screen. Do you see Windows load?

If that works, then everything else is fine and you've narrowed the problem down to the graphics card. Since the rest of the PC is getting power correctly the next steps would be:

(While the PC is off and unplugged)
- Remove the graphics card and put it back in, making sure it is correctly fitted into the motherboard.
- Remove the power cables on the graphics card and plug them back in, making sure they have a firm connection
- Check that the power cables that run to the graphics card are secure on the power supply plug-in as well
- Turn the PC on

If you still don't see anything take the monitor video cable and plug it into the motherboard video port so you can use the on board graphics.

- Go to this webpage and download the drivers for your graphics card model: http://www.geforce.com/drivers
- Install the drivers and shut down your computer
- Plug your video cable going from the monitor back into the video card
- Turn on the PC

IF you still don't see a picture after this then there is a good chance the card is bad. The last thing you could try after this is to install the video card in another PC and see if it works. If it works in another PC, then there must be some connection not being correctly made within the new case.

yes, windows boots, but video card is a black screen. Then it automatically switches over to the on board graphics.

The video card does work. He tried it in another computer and it worked.
He gets a black screen with the new video card on his. Windows runs and everything but video card displays nothing and then it will then switch over to on board graphics. I told him about downloading the drivers and he said he didn't think of that and was going to try it. But then his dad told him it wouldn't have anything to do with it and that caused him to stop. How important is downloading the drivers. He believes of course whatever his dad says but his dad is also trying to buy the video card off him for a friend soooo I don't know if I can even trust what he says.
