I was helping my friend install a cd/dvd burner into her computer and now we can't get it to run.  I have four green notfication lights on the rear and the fourth one is yellow.  Does anyone know what this means and how I can fix it?  That is if it is fixable.  Thanks! Have you read the instruction manual to see what the yellow light means? Also, have you install the drivers properly?

[glb]Flame[/glb]I didn't think to check the manuel, I will do that.  I can't make sure the drivers are installed though because the computer won't load.  It is just stuck at the dell start up screen.Everything is fixable given enough time and MONEY.  
What is necessary is information. Make of computer, MOTHERBOARD, memory, BIOS type, etc., etc. Need the 'numbers' before we can add them up. Did you change anything in the BIOS or CMOS? Were there any beep codes when you started it back up?
By the way, this could have gone into the hardware section okay.
Hopefully helpful,
jimOkay, I looked the light codes up and it means other failure.  The computer is a Dell dimension 4100, w/ pentium III, 733 MHZ, there is 384 non-ecc MB of memory, the system BIOS chip is 4m (512 KB), I'm not sure about the CMOS or the type of Motherboard.  It is all what was basic in this computer in 2001.  The OS is XP.  I didn't change anything except for the the Cd drive and Dvd/Cd burner.  I'm at a loss as of what to do.
