I suspect a Windows update from many months ago. Too late to roll back, and a clean load is not an attractive option for me. Laptop is OLD, but this never used to happen. I've seen some of your members get this solved, so I thought I would see if anyone here can help. I downloaded LatencyMon, and it certainly looks like storport.sys is a likely problem - screenshot attached. I used to be a pretty capable geek, but now I'm mostly a user. Running newest available drivers for nVidia graphics, latest BIOS. Tried disabling CPU speed limits and Intel SpeedStep in BIOS. No joy. Suggestions are very welcome. Thanks for your time.
