My father and I just finished putting together my new build, and I am having some issues with the GPU. I've been searching around for a few hours now and trying a lot of different solutions, but I'm still stumped. If anyone could shed some light on this, that'd be great.

These are my specs:
ASRock H97m Pro4 LGA1150
i5-4590 3.3Ghz Quadcore
MSI nVIDIA GeForce GTX760 2GB
Rosewill Capstone 550W PSU
Samsung 840 Evo Pro
(Also a 1TB HDD that has yet to be installed; need another SATA cable first)

I booted my computer and installed Windows 8.1 onto my SSD just fine. I installed all the drivers from the CD ASRock provided me, and then disabled the Intel HD Graphics 4600 driver (which is my onboard graphics, if I'm not mistaken) and then rebooted. I also tried configuring my UEFI settings but found that it wasn't available in the boot options menu that you get to by holding Shift while pressing Restart on the Charms bar. I took a guide through the UEFI on my motherboard's BIOS, but it said that UEFI was already enabled, so I decided not to mess with it. The issue is that any time I install my GTX760, I connect the PCIe connectors, connect my VGA cable directly from my monitor to the GPU's VGA input, and the power on the computer only to find that my monitor gives a "No Signal" screen and then goes into standby/sleep mode. The GPU's fans spin without issue. My computer is still running and I believe it is booting to Windows, I just get no display. My MOBO did not include a PC Speaker so it is not beeping regularly, to the best of my understanding. I am stumped here and any help would be greatly appreciated, again my PC is working just fine without the GPU installed but there is no display with it installed. Thanks!

You shouldn't need to disable the integrated GPU. Re-enable it, start your computer with the GTX 760 installed, but VGA cable plugged into your mortherboard. Try installing drivers for the GTX 760.

Once driver installation is finished, switch the VGA adapter to the GTX 760.

See if this fixes anything.

Unfortunately it appears that I am having the same issue with the VGA cable plugged into the motherboard's input. I re-enabled the onboard graphics, shut down the PC, installed the GPU by plugging in the 4-pin and 3-pin PCIe connectors, and still I get the "No Signal" display followed by standby mode after turning on my PC with the monitor on. I also tried turning off the monitor and turning it back on while the PC is running, but that did not help either.

Do you have another cable you could temporarily try? Just curious.

Also, what happens when the GTX 760 is installed, but the power pins are not connected?

I have an HDMI cable but no DVI cable. My monitor however does not have an HDMI port, so I tried to use my television. However, I was never able to get HDMI to work with this TV with my last desktop (though it works without a hitch with my laptop), so I wasn't surprised when the TV wasn't able to retrieve the signal either.

When I disconnect the power pins but leave the GPU in the motherboard (with the VGA cable in the motherboard's port), the fan on the GPU spins (as well as all the other fans, including the PSU, though I know that doesn't necessarily indicate there isn't an issue with the component) but the monitor still does not receive a signal.

Thanks so much for your time, by the way. I appreciate it.

Not sure if this will help at all, but the problem sounds a lot like one I have had. I fixed it by flipping the switch on the back of the PSU, waiting for about 10 seconds and then hit the power button to make sure all the power is drained from the mobo, and then flipping the switch back and giving the pc a good 30 seconds before you turn it on. I realy dont know how this works, but it worked for me several times and I guess its worth a try.

Hmm. Try this:

1. Turn off the computer and unplug
2. Remove Graphic card
3. Plug the monitor to your video output
4. Turn on the computer
5. Click on start and type msconfig
6. Select the Boot tab and click on the box that says Safe boot with minimal selected.
7. Apply then click ok.
8. DO NOT RESTART.
9. Shut Down computer and unplug
10. Install Graphic card
11. Turn on the computer (should boot into safe mode)
12. Go into Device Manager
13. Expand Display Adapter
14. Disable the Intel(R) HD Graphics 4000 driver. (DO NOT UNINSTALL)
15. Click the start button and type msconfig
16. Unclick Safe boot
17. Restart

Unfortunately I get to step 11 and am unable to continue because my monitor is still not receiving a signal.

Did you check to see what 'input' the monitor was set too? Hdmi, display port, dvi etc

Darn, well it was worth a shot. Let's see...

A few things to try:

reset CMOS.
Try a different PCI slot
Try a different cable/port on the GPU
Try a different computer with the 760

I always overlook the simplest things. Yes, definitely try this!
