Games failing when using two GPUs might indicate a power supply issue.
I've been troubleshooting crashes with two GPUs on my PC: an old RX 5700 and a brand new RTX 4070 Ti Super OC. Here’s the summary of the errors. I used BlueScreenView to extract the minidump files and this is what I found. RX 5700: Crashes with VIDEO_SCHEDULER_INTERNAL_ERROR (0x119), caused by watchdog.sys . RTX 4070 Ti: Crashes with DRIVER_IRQL_NOT_LESS_OR_EQUAL (0xD1), caused by nvlddmkm.sys . System Specs: Ryzen 7 7700, Gigabyte B650M Aorus Elite AX, Corsair 850W PSU, 32GB DDR5 RAM. Troubleshooting so far: Clean driver installs (DDU for both NVIDIA and AMD). Stress tests (no issues in OCCT/FurMark). No WHEA errors in Event Viewer. RMA'd the 4070 Ti (passed their tests). Tested with both GPUs – same issues. Could this be a PSU, motherboard, or software issue? Both logs suggest GPU-related problems, but it’s happening on two different GPUs. Any ideas? Also, the RX 5700 seems to be more stable. I can run Overwatch 2, for instance, for much longer without crashing compared to the 4070 which crashes within minutes. I know the 4070's tdp is WAY higher, so, could this indicate a faulty PSU?

Voltages seem fine although I'm not an expert in PC voltages. I've read that all rails must stay within 5% of their rated voltages. They seem very stable in this sense. CPU is also fine in the tests, temperatures are great as well. Here is the log the last crash in event viewer: The computer has rebooted from a bugcheck. The bugcheck was: 0x00000119 (0x0000000000000001, 0x0000000000000000, 0x0000000000082737, 0xffffd10dc72c2000). A dump was saved in: C:\WINDOWS\Minidump\020525-15062-01.dmp. Report Id: 6e5e5028-5606-42a9-9b4e-4b973bf95d82. In the minidump file I found out it was a watchdog.sys . driver error that triggered the crash. My PC did a hard reset when Diablo 4 crashed last time.
I've seen those BSOD alerts before—like when I pushed my graphics card too hard (watchdog error), with a failing i7 using the irql driver, or when I tried to overclock an i7. It might be connected to memory issues, but you should double-check that first since my memory of it is fuzzy.
You're referring to RAM, and you're preparing to run the Memtest86+ at least four times to verify everything is working correctly.
