USB connections not working..

Go into Control Panel>System>Hardware>Device Manager an dlook at th ebottom of the list at the USB devices. If all or any have yellow marks beside them, click on one and go to Properties then Driver Details and click the Update Driver button.

Post back with what happens next.

ok well first off theres none with yellow marks.. i have a +Universal Serial Bus with 4 tabs - underneath that say Intel(R) and 4 more tabs that say USB Root Hub.. i had this problem on my other computer and brought it to a shop and the guy fixed it by going into the STARTUP menu when u first turn on the computer, its like he had to enable a bunch of ports, but i dont know how to do that on this computer its a DELL laptop, i can get into the BIOS but it doesnt say much about USB ports. And i dont have enough money to have someone go fix it i know its a simple to fix i just dont know where to do it!!! HELPPP MEE!! LOL

try F2 to enter the BIOS when you start your laptop

You're looking in there for anything that implies USB ports are disabled.

Go back to device manager.

Expand Universal Serial Bus controllers,
Delete all except the above device section identifier.
Re-boot computer, Windows finds all controllers again and loads drivers.
