I have the exact same situation on an F5-573-55LV. I've upgraded every possible driver and the BIOS is now v. 1.23. I know that Lenovo fixed this with a BIOS upgrade. The upgrade to 1.23 did nothing, nor did reinstalling Win 10. My current version is 14393.rs1_release_inmarket_170303-1614.
The errors are coming from the Intel PCI root ports #11 (9D1A) and #12 (9D1B).
The system is the same as when it was purchased - #11 has a Qualcomm QCA9377 wifi and #12 has the Realtek RTS5287 Card Reader and the Realtek RTL8168/8111 Gigabit Ethernet adapter.
If I disable the three devices then the WHEA Event ID errors stop. In the last 24 hours I've had about 2500 of them.
I've tried older drivers, updated drivers, ACER drivers, and various combinations. Nothing has solved the problem.
There are a ton of people that have this problem - not just ACER owners, although there are a number of threads about it on this site. Here are a few links to discussions:

Please advise ASAP. This has been going on for a long time with no resolution.
Thank you.
