Hello,

I very recently began a valiant attempt to build my first custom computer - something of a somewhat-budget gaming PC. I spent the last several weeks buying parts and two nights ago finally began construction. Everything went pretty smoothly until I tried to install the GPU.

First, let me list my specs.

Motherboard:
ASUS Z97-A
RAM - G.SKILL Ripjaws X Series 32GB (4 x 8GB) 240 PIN DDR3 SDRAM
Case - Corsair Carbide 400C
PSU - Corsair CX 750W
CPU - Intel Core i5 4690k @ 3.5 GHz Quad Core
SSD - Sandisk 240 GB SSD (Used for OS)
HDD - WD Black 2TB HDD
OS - Windows 10 Home 64 Bit
CPU Cooler - Corsair HydroSeries H115i
Sound Card: Creative Labs SoundBlaster Z
GPU: Gigabyte Radeon R9 380X 4GB

I installed everything and powered it on, and got a solid red light on the "LED BOOT DEVICE" light on my motherboard. I followed the instructions in this post ( http://www.tomshardware.com/faq/id-1893016/post-system-boot-video-output-troubleshooting-checklist.html ), and when I took out the GPU and tried again, BIOS ran and I was able to get everything going, install the OS, install all the drivers, ETC.

Once I got that all sorted out, I tried installing the GPU again. I've been hitting a number of problems. Firstly, it will NOT fit in the PCI-E 16x slot closest to the CPU. I've tried for 3 hours to get the little bleeper in there and it will not fully snap in. If I pushed it in any harder I would've snapped my board. I've tried loosening the motherboard screws to get more wiggle room, and still no luck.

So, I installed it in the second PCI-E 16x slot. It fit in nicely to this one. I plugged it in to the PSU, screwed everything in, and tried again. Same problem. No signal output from the card, but I did get a signal output from the board, at least. Win 10 booted up, but the motherboard does not seem to be recognizing the GPU. I went into device manager and the card isn't listed anywhere, under anything. I installed the drivers off of the CD that came with the card, and all I get when I try to run the software that came with it is a popup message with, "Please confirm whether to support this VGA card!'' The instructions that came with the card are useless and have literally nothing for troubleshooting, so I tried looking in the motherboard booklet. It said that I may have to configure BIOS to accept the card. I tinkered around in BIOS and it is set to automatically detect and choose any PCI-E card over onboard graphics. It also said that I may have to assign an IRQ to the card, but I have NO idea how to do that. Seeing as it won't even detect the card, I don't think that is the issue?

The card is receiving power - the fans are spinning and the little LED logo is lighting up. It is also fully connected to the board.

I've been at this for two days and I am at the point where I want to rip my own hair out and hulk smash this thing against the wall for good measure. I have no idea what is wrong and what to do next.

Any help would be greatly appreciated. I'm pretty close to just figuring this thing is defective somehow and asking Newegg for a refund.

Edit: I'm using the DVI output, not an HDMI. I read that sometimes the card can have a bit of a tantrum with HDMI cords if you don't configure drivers and whatnot first.

If the car is giving you output in the BIOS and also in Windows (even on the default VGA drivers) it's seen in the system and you don't need to change any BIOS settings. The card is detected by the system or you'd get no video display at all. Issue is that it sees the card but not as the right type. Few things can cause this, are all the power cords in the card? The 380X should require two of them.

Why can't you get the card in the first PCIe slot? You likely had something in the way, usually when that happens the bottom of the backpane is hitting something. Check exactly where it does not fit. If you tried to get it to fit and something was off, a connection may have been damaged. Try the card in another computer with a good...
