It was all great until about 10 days ago. Now my new desktop PC is taking five to seven seconds just for a simple keystroke to display. Same for opening a browser tab or Explorer window. I/O operations are even slower: opening a video, or Word file. Everything is running similarly slowwwwwww. Previously, it was all blazingly fast.

NOT installed. Windows Update is otherwise current.
McAfee and Norton scans not finding anything.
No new software installed.
- Task Manager reports 7% CPU use
- 46% Memory use (Chrome is the biggest hog at 1.7GB)
- Paging file set to 81,920MB (shouldn't be needed, though)
- All system settings are factory default values
Short of doing a factory reset, do I have any other options?
No, I haven't booted into Safe Mode yet. That's next, though I'm not sure what that would reveal.
Modem and router rebooted, just for good measure.
I'm wondering if a not-very-nice website could have installed some surreptitious evilware.
Thanks in advance; I'm kinda stumped.
