Hello! Several months ago I started losing signal on my two monitors intermittently, requiring me to hold the power button until the system went off. When I powered it back on they would work fine. It was usually weeks between having to do this so I didn't think much of it, but recently it's happening more and more often. Sometimes the fans go crazy and sometimes it will reboot by itself but neither one happens every time. This usually happens when gaming, but not always.
If I plug the monitors directly into the motherboard and unplug power from the GPU, everything is stable and works fine.
Some things I have tried so far that haven't worked:
Yesterday was my best day in a while, running for 6 hours or so. I was able to play a game. I ran the intel processor diagnostic. I ran unigine heaven benchmark on extreme. I thought I was good, but eventually got the same result. No errors were in the event viewer immediately before losing monitor signal, but I do see some DCOM errors about 4 hours prior. I plugged the monitors back into the motherboard after that and the computer is still up and running now, 17 hours later.
Specs:
Motherboard MSI Z490 Gaming Plus
Intel i7 10700k (I am not overclocking)
32gb Crucial Ballistix 3600mhz dd4 ram
MSI ventus 1660 super GPU
Samsung 970 evo NVME drive 500gb
Samsung 860 evo SSD 1tb
Corsair AX850 PSU (backup PSU is Corsair RM750e)
Thanks for any help.

Some things I have tried so far that haven't worked:
- Uninstalling the drivers with DDU and clean installing them.
- Installing old drivers from Jan 2022.
- Allowing windows to download GPU drivers automatically after uninstalling and rebooting, not manually installing any.
- Adding TDR entries to the registry to create a longer timeout delay.
- One of the system errors I got was "cplspcon" terminating, so I disabled the intel HDPC service.
- RMA'd the graphics card twice.
- Brand new card (which I ended up returning because it was still happening).
- Using a different PCIE slot (with both cards).
- New power cable from PSU to GPU.
- New power supply.
- Plugging computer directly into the wall instead of a UPS.
- Ran the windows memory check diagnostic, no problem.
- Repaired windows (keeping files and apps).
- Ran sfc scannow repair, which did find something and repair it, but ran it again several times afterwards with no problems.
