Dell only supports Windows XP and Windows Vista. If you look on the Dell website you will see that dell has not provided support for either Windows 7 nor Windows 8.

After a while my computer freezes, and then it doesn't boot up without being in safe mode. To find a driver for this device, click Update Driver.
