Dell Dimension 2400 -- No video (No Beeps)

Hello,

I am having a problem with my Dell Dimension System When I turn it on it doesn't display any video on the monitor. Now I have tried two monitors and neither worked therefore it isn't the monitor. I have an integrated Intel graphics accelerator on board. Also, I have checked the status code lights -- Found on dells website. this flashes first but quickly disappears: "AD" is lit orange which refers to IDE bus failure has occurred. and then this flashes and stays: "BC" is lit orange which refers to System board resource and/or hardware failure.( I believe this could be the GPU )


any help would be appreciated,

thanks puzzledplane

through, removing certain parts the cd drives and the hard drive the computer posted and the bios screen came up and i now have a bios screen.. Also the status lights are not lit orange only lights "D" which refers to Other failure. here is what the bios screen says Diskette drive 0 seek failure.the computer also does beep.

Solved with a reset and reconfiguration of bios
