Week ago I have experienced serious mouse problem. First it has begun to behave strange. Mouse pointer has started to stop from time to time and then it has started to move without my steering. Then it has started to open different windows by itself and finally it has stopped to work. I have succeeded to return it in life with a System File Checker with command sfc /scannow and for some period it has continued to work properly but from time to time it would behave in the same manner and after few days it has stopped functioning. I have tried to reinstall windows and mouse would work properly few hours and then it would stop. I have suspected that I have caught virus on the internet and I have formatted whole partition and have installed new windows but it has happened the same thing. After that I have tried to delete partition C and create new one but instead partition system deleted whole disk and I have lost my data on partition D and I have the same problem with mouse. Several times I have succeeded to recover mouse by clearing CMOS/BIOS but it was for short time and after installation I have experienced the same problem which I have now. I have noticed that also other people have got the same problem. If someone has resolved this kind of mouse problem please tell me what I have to do.
