I have an ASUS ZenBook 4GB solid state drive laptop, running Windows 7. Intermittently, I have noticed that 1 or the other built in USB ports fail, or the SD card reader fails (and the webcam only functions when I run Skype - but that may be another matter). There are no errors that I can find anywhere and no warning that the component will fail.
What may be causing this? Also, is there a way I can check to make sure these components are okay?
