Is it Vista or the Dell Laptop but two USB ports on the right hand side have stopped working whilst the two ports at the rear are still functioning correctly. I have tried restoration unsuccessfully and have run out of ideas.. Helpm Ratler.
This is a very easily missed fault with USB Ports not working correctly. PSU faulty.
As mrwoowoo says also just check their are no yellow exclamation marks in your Hardware list. If their is then you will need to download or from you Dell Driver Disk the Intel Chipset Driver which will replace and repair missing driver if not the drivers then its most likely the Power Supply unit being faulty
