On that note, have you checked Windows' Task Manager to see if anything pops up and uses a lot of CPU/Memory/Disk when the lag happens? Sort the columns.. or check the performance tab for spikes.
With what you're describing in your second post, it probably wouldn't show anything, but could check the Performance meter in reaper too for any abnormality.
Task manager would probably be a quick and dirty way to tell see if there's a big spike happening on your CPU/memory/disk/network/etc. In particularl, 100% CPU/Disk/Memory or even network usage. Just keep task manager up as you're doing your thing, and when things freeze up, check if one of those is hitting 100% (or even close).. then it might be a simple matter of sorting that column under processes and see if some process (other than Reaper) is pinning that resource. As rudimentary as it is, the task manager can probably at least narrow down the problem.. within Reaper or something outside of Reaper (what you seem to be suspecting, with a "background process").
And while you ruled out buffering, I'll just say it anyways, of course make sure that while you have ASIO drivers installed on your PC, you're actually using them in Reaper's Audio prefs. Also, in regards to not having a high performance power plan, you might be able to add it yourself (
see here). That might be a good idea to do, in case something is going to sleep on you.
