Hi guys, I hope someone can help me. I recently upgraded my ASUS Rampage IV Extreme (BIOS 4901) build from a i7-3930K to a E5-1680V2 that I found on eBay. It was fine, it POSTed the first boot, Windows had no issues, but then I noticed that at seemingly random intervals, the screen would look like the picture below, and after a couple of seconds go black but the PC is still on, and I must manually reset the computer to recover.
First thinking it was either my OC, GPU, or motherboard, I disabled all OC's and tried my GPU in another PCIe x16 slot and the same issue appeared, then I tried DDU'ing my GPU driver, no luck, and finally I tried a Windows reinstall multiple times, paying special attention to which drivers got installed as Windows has me download chipset drivers, same issue with or without new chipset drivers. So, thinking it was my GPU, I tried my brother's spare working GTX 1070 in both PCIe x16 slots and the same issue persisted even after a DDU. I then reinstalled my old 3930K and under the same workload that would cause a crash (MSFS 2020 downloading game files) there were no issues. So, thinking it was just a bad stock from eBay, I contacted the seller and he said I could do an exchange if I pay for shipping back, which I did, and then I installed the "new" CPU (which indeed appeared to be a different stock that what I sent) and the same issues popped up. I have tried both Windows 10 Home and Windows 10 Pro thinking it might be a Home/Xeon issue, but no luck.
Specs
Motherboard: ASUS Rampage IV Extreme (BIOS 4901)
RAM: 64GB Corsair Vengeance Pro DDR3 at stock speeds (not XMP)
GPU: EVGA GTX 1070 FE or PNY GTX 1070 XLR8
Expansion Cards: EVGA Nu Audio Pro 7.1 (Main and Daughter Card), TP-Link Archer TX3000E WiFi Card
I am just posting here because this seems to be the only sort of active place left that is talking about Xeon's and I am just at the end of my rope. From everywhere I have seen online, this setup should be working even though it is technically not on the QVL of the motherboard (E5-1660 V2 is though).
Thanks to anyone who can provide any guidance.
