Discreet Graphics Card Causing Boot Loop [RESOLVED]

Hello all,

My build is as follows:

Case = Corsair Air 540

PSU = Corsair TX750

RAM = 16 GB DDR3 Corsair Vengeance

CPU = i5-4690

Motherboard = GA-H97-D3H (flashed to latest BIOS version)

Graphics Card = Asus Radeon HD 7950 DirectCut II

SSD = Crucial MX100

HDD = Seagate Black 2TB

Installed USB Peripherals = CM Storm Quickfire Pro keyboard; Sentey GS-3910 laser mouse

Display = 2 Acer 1080p 23" monitors connected to Radeon card via mini-DisplayPort to HDMI adapters

The problem: I've had this happen with three separate 97-series motherboards (the one listed above, an MSI Z97 Gaming 3, and a GA-Z97-UD3H). Whenever I boot up from a cold state with my Radeon card plugged in, the system goes through an infinite boot loop. It will only boot properly when I hold in the reset button immediately after initial power up (and even then I have to try it a few times to get it to work). Once booted up, it resets and wakes from sleep mode just fine. Whenever I unplug the Radeon completely and just use the onboard GPU, the system also boots fine. I first thought it was the card going bad, but it works perfectly whenever I plug it into my old ASUS P8Z68-V-PRO-GEN3 with an i7-2600K chip.

I've gone through several related threads and checklists on here, and can't seem to find a solution.

Any thoughts on what the problem might be? Is my card just not compatible with 97-series boards or Haswell chips?

  1. Have you tried hd 7950 in any other motherboard than the 97 series motherboard? Can you try your card in your friend's motherboard?

    Hey goku,

    Yes, I plugged into my old ASUS P8Z68-V-PRO-GEN3 with an i7-2600K CPU and it worked fine. I even tried unplugging all USB devices on boot up and no dice.
  3. Hmm then it might be the motherboard compatibility like you said. If this motherboard is working fine then you should sell it, you can get nice money off of it and can buy a non 97 series motherboard. Have you checked for BIOS update for the card?

    Updated the card's BIOS to current (Oct of 2012) and it never worked right again. When I rebooted it said no AMD card was installed even though device manager detected it. Subsequent reboots won't even allow it to display anything on the screen period. So I re-enabled onboard graphics to even get a display. Now I need a new card, and what guarantee will I have that this same problem won't occur?

    Problem solved. There's something with the HD7950 itself that was causing the problem. I get a new R9 290 and it now works perfectly every time. So yeah, if you have a Haswell CPU, don't get a Radeon HD7950.
