I have a homebrew computer with Win 7 & it has worked flawlessly for several years. Recently the mouse has been freezing up, sometimes for a few seconds, sometimes much longer (Mouse is a Logitech M215, KB is Logitech K330 & they both communicate via USB receiver.) I have looked for a solution online: one post said it might be the router but I shut it down & the problem is still there; others suggested uninstalling the mouse driver which I have done. I even updated the SetPoint sw, no joy. So I am looking for other solutions before I give up & load Win 10; unfortunately a couple of sw packages will no longer run if I do that. Any suggestions? Thanks!
