The *ONLY* place inside a desktop computer for a fuse would be inside the power-supply unit. Expressed differently, there are *NO* fuses being used.

You can download the drivers from Dell WEB site, the support download page. Make sure you select your model laptop, better still, type in the Service Tag number, it is printed on the label on the bottom of the laptop. This will open the page where the specific drivers for your model laptop are located. Also make sure you select the Windows XP or Vista version of the driver for your Windows operating system.

Open the case and look at the little black round things that look like soda cans. Those are called Capacitors. they are kinda like small batteries. They should have a shiny silver top. If they have anything oozing out or if they look like theyve popped like a popcorn kernel, then you have a faulty board. If your pc is under warranty, call dell asap. its an easy repair and its done the next day.

If you dont already know, you dont want to mess with it. (Theyre inside the power supply, chances are extremely slim they are causing an issue)
What symptoms is the computer having? Any beeps or messages displayed on screen? Etc
