Good hours, bad, sluggish hours and randomly switching between those states …
That is my Windows 10 Pro 64 on a Thinkpad T560 Intel i7 6600 with 32 GB and SSD, typically kept up to date.
It had been “poorly” for a while and I eventually decided to refresh Windows; something I have never had to do before (ordered Oct 2016). I obtained Windows from the MS download site – it turned out to include 2004. I installed using the option to keep data and programs and that seemed to go fine.
Since then it has sometimes runs OK, then other times been slow or unresponsive for several minutes at a time. Task mgr reports cpu trundling along at 30 – 55%, with no apparent disk activity problem.
Sometimmes it is web pages that are stuck, sometimes an app or the start button that is unresponsive. As I type this into Chrome, it is Win task Mgr that is stuck.
Malwarebytes, Vipre anti-virus and Win Defender scans all report no problems.
I am stuck. Once I was reasonably techie in Windows matters, but 20 years retirement means I am rusty.
I should be very grateful for an suggestions as to what may be the problem.
Thanks, David
