Help. Win and browser(s) auto refresh + date and time auto text input.

My Win10 PC is unusable. It's been happening for 3 days now.

I boot up, and sometimes it's almost immediately, others times may take a little while, but sure enough it eventually starts auto refreshing the web browser (be it chrome, opera, edge), the taskbar or any window become unresponsive, and if I open notepad it will spew out timestamps in this format: 27-Feb-193:20, at the rate of about 4 a second. Reebooting is the only short lived way to make it stop.

I did full scans for viruses, malware. Checked disks for errors. Made sure windows+all drivers are updated. I browsed around since auto refresh seems to be a common issue, and the solutions range from scanning disks to disabling certain appearance/theme settings, to actually what is my top search result which is, disabling windows error report :/ Thats the only one I haven't tried and that I'd really like to avoid :) Also would really like to avoid restore/rollbacks cause of the mountain of software Id have to reinstall.

Anyone out there with some light on this? Thanks
