CPU spikes are most of the time here traced to HDDs that have issues.
Karnac tells me that your SPECCY report and the values 01 and 07 of your HDDs may be in the thousands. Take a look or share the report here.

I'm a Windows 10 user, and recently I've had issues where, as I've been watching videos and working on things online (sometimes with multiple tabs and split screen), my computer will suddenly disconnect from the internet and reconnect soon after. There will be issues on the video I'm having where there will be sound distortion before the video stops due to the dead wifi.
I'm certain its only my computer, as my phone still works with wifi during these moments.
When I open my task manager, it shows CPU at 100% before dropping back down.
Is that just task manager needing a moment to load when I open it, or is something giving me CPU spikes? Can CPU spikes lead to your wifi card or network adapter to stop working? Is this just a sign that my adapter or card is on its last legs and will need to be replaced?
