My mouse disconnects randomly well i think its my mouse

Ok well i have built a gaming pc that is working brilliantly, i have downloaded numbers of games to try and play but the worst thing is my mouse, i have tried two mouses in every different usb slot, i have also tried to reinstall drivers. No change. I made it so my computer can't turn my mouse of to save power still no change… You see i would be playing minecraft for example as happy as ever but id be running along one moment and then the game would pause and it would take me to click to resume or another example would be typeing something like this out then it would randomly make me reclick where it disconnected just for me to resume typing… I'm not too sure what's wrong but typing this out has gave me atleast 4 reconnects and its very annoying, many thank can someone please resolve this for me

Did you run the motherboard driver disk after you installed OS? Are you using wired or wireless mouse? If it is wireless, try a wired mouse instead. Go into device manager and see if you have any warnings. I've never had that problem so I don't what else to tell you, I'm afraid. I can only recommend you take it to a local PC computer fixit place and see if they can help. I know it's an extra expense but right now you have an expensive brick.
