I am regularly rebooting because of mouse hanging up. I suspected a problem with the OS, and reinstalled ubuntu 18.04.2-64 bit. This resulted in no change. The mouse hangs up most often in AisleRiot solitaire and even hung up twice today while in Google Earth pro. Question? is the problem in hardware or software. I have a home built computer; MB:Giga-Byte GA-H270-HD3P; CPU:Intel G4560 @3.50 GHz X4; RAM: 15.6 GB Crucial DDR4-2400 UDIMM; Storage-3.2 TiB, (640 GiB, 500 GiB, 2.0 TiB); Microsoft wheel mouse optical USB and PS2 compatible. Where do I start?
