Incidentally, although the suggestions by pcwork may solve your problems, the point is you should not have to do it.
You don't sound likke you're running any sophisticated or demanding software and the whole idea that you need to delve into device drivers, hardware, software and configuration changes is appalling when these problems have arisen through no fault of your own on a new laptop.
Well intentioned fiddling in configuration settings etc have destined many a PC to service workshops. Think carefully of the inconvenience to yourself and ask yourself if it's really worth it.
