Using default boot option "Ubuntu, with Linux 5.4.0-42-generic" leads to slowness and multiple monitor errors

My desktop has two pretty new SSD hard drives (a couple months old each). One of them has Windows 10 which I use for gaming, the other has Ubuntu 18.04.4 LTS which I use for work. CPU is Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz, RAM is 32 GB DDR4, graphics card is a NVIDIA GeForce GTX 1070, and motherboard is a MSI MS7972. I have dual monitors attached directly to graphics card output, one in a DVI the other in a DisplayPort.

Up until today this desktop worked fine without a hitch (built in late 2016, two SSDs are the only new parts since first build). It even worked fine yesterday evening. This morning though, I boot up with the default Ubuntu option and my second monitor isn’t detected, additionally the system is running EXTREMELY slow. I boot into Windows and everything is working fast and both monitors are detected and running just fine. Even start up Witcher 3 and run it a bit to make sure everything is going smooth. I boot again, this time choosing advance Ubuntu options and running Ubuntu, with Linux 5.4.0-42-generic. Again the system is EXTREMELY slow and only one monitor is detected. So I instead I boot up again with Ubuntu, with Linux 5.3.0-62-generic. Now both monitors are detected and it is running as fast as ever.

I did some searching and found some threads with people suggesting an investigation of any BIOS settings that might be slowing down the CPU. I couldn’t find any settings that seemed like they would slow it down and I couldn’t find a similar question anywhere. I assume the issue is related to an update but I’m not sure how/what caused it. I’m concerned that as new updates comes out, the option Ubuntu, with Linux 5.3.0-62-generic may also get the same issues for me and then I’ll be kind of stuck. For now using Ubuntu, with Linux 5.3.0-62-generic is fine, but I’d really like my default and the latest startup option to work again.
