I&#x27;m in the same boat.  Steam was DESTROYING my PC for a long time.  I couldn&#x27;t figure out what it was and finally tracked the random spikes and focus losses to Steam&#x27;s update service being corrupt.  Re-installing Steam means uninstalling everything you&#x27;ve downloaded with steam, possibly losing save games and stuff like that, then having to wait for everything to re-download and install.  There are ways around it, which I found later but I had already screwed up half of my downloaded games because I had assumed that I would be able to just do a uninstall-reinstall on it without losing all of my stuff.  Total garbage.  I will definitely not be using anything like steam, in the future, if I have any choice in the matter.
