Sorry if there's a better place for this, but I just made a new PC build and am having a problem with my RTX 4070. Shortly after startup (either a few seconds after the BIOS setup screen loads, or during Windows load), the video output freezes shortly after the GPU fans turn off, if that means anything. Even if I stay in the BIOS setup menu (i.e., not getting into Windows at all). I *think* the PC still runs when this happens as I've keyboard-navigated to shut it down in Windows.
Using the integrated video output from the motherboard (HDMI), everything runs fine.
I have verified that the video card works fine by putting it in this computer's precedessor - no problems. I have also verified that this new motherboard/PCIe slot work fine by installing the GTX 970 from that older computer in this new one - again, no problems. It's just the combination of the new 4070 and this new computer. I have tried reseating things about a dozen times as well as various combinations of PSU output ports and cables to power the 8-pin PCIe connector on the video card. Build is as follows:
Motherboard: ASRock B650I LIGHTNING
CPU: AMD Ryzen 7 7800X3D
GPU: GIGABYTE WINDFORCE GeForce RTX 4070
PSU: CORSAIR RM750e
RAM: G.SKILL 2x16GB DDR5 6000
SSD: Crucial T700 1TB
I have updated everything I can through Windows, and also have updated the BIOS to ASRock's most recent version listed (1.30). Interestingly, the only way that I can actually crash the computer (that I know of at least), is by plugging 1 monitor into the motherboard output and another monitor into the video card (both HDMI) . In this case, if I select "internal graphics preferred" in the BIOS, then during Windows startup I get the error in the attached pictures, "system thread exception not handled," which doesn't seem to help much. This doesn't happen if I say "external graphics preferred," even though the output is still going through the internal graphics, since during bootup the video card stops working. During any situation, Windows does not recognize a second monitor attached, but HWMonitor lists the 4070 (though the only things it shows as monitoring are utilizations, all at 0).
I tried reflashing the video card VBIOS using nvflash, but command prompt gives me an error that the "PCI BAR assignment for the processed device is invalid," which doesn't change if I have Resizable BAR either enabled or disabled in the BIOS.
I've also tried installing my old PSU (500w) in the new computer. The only change with that is that Windows device manager says it is working fine, whereas with the Corsair 750w, it says Windows disabled it due to a problem. I still can't use it or flash the VBIOS though. And it still freezes in the BIOS tool itself.
Any thoughts? This issue is driving me insane. Thank you in advance!
