I have had this laptop for almost 2 years now, and recently the usb's have started acting funny. In one port I have my bose sound system connected, and in the other I have my mouse connected. When I am using my computer, my mouse will occasionally stop working for a few moments, then chime the tone when a new usb device is inserted and work again. It will keep doing this for a while until the mouse eventually doesnt work anymore, and at that point nothing comes out of my bose speakers either. I have tried reinstalling drivers and updating them, but so far there has been no progress made. I have read that when all of the usbs stop working at once, it is due to a motherboard problem, and I am hoping that is not the case. If I unplug the devices that use usb ports, then plug them back in around half an hour later, they work again, but will do the same thing. Does anyone have any idea what I should do?
