I just got a computer built and a friend loaned me their Dell UltraSharp 1800fp monitor. I connected the DVI cord and the monitor turns on, but nothing happens. I set up my wireless mouse, which works fine with my laptop.
The monitor screen says stuff about IDE Channels and Warning! CPU has been changed...please re-enter CPU settings in the CMOS setup and blah blah blah. How can I change any settings if nothing is working? Any ideas, please help!

Re: Monitor on but not working properly
If you just built the computer..the motherboard will give you a warning that some hardware has changed. you have to connect your keyboard and go into the bios and make sure everything is right. To be safe select set to default factory settings , save and reboot the computer. This is to prevent the settings for a previous cpu be used for the new one.

Each monitor has a different response to "no activity" from the system. So for the monitor, if you get a chance, try your monitor on another machine that you know does function. At work, neighbour, or other.
For the computer, does the it (beep) or POST (Power On Selft Test) when you turn it on, do you see and hear what you would if the monitor was connected?
If it sounds normal, then everything should be fine and luck might have it, your backup monitor is not working either, try another one from the same friend or neighbour above.
If it doesn't POST, you could have a video or other card or ribbon connection loose in the computer. Either you or a friend, or the service center, whichever feels comfortable reseating all the external and internal equipment, bearing in mind static electricity and proper handling measures for the computer.
It could be a setting problem, power saver setting, or a mode that the monitor does not really support - things like refresh rate - or actual hardware.
Easiest way is to borrow another like monitor, and say another video cord and see if the problem remains, or if a newer monitor says 'out of range' or similar.
Then, if you have a fancy video card,remove it and use something primitive. Not reading instructions is a big cause.
If its not a setting issue, and as the inverter board is ok; if the above description is correct, reseat the inner board connecting cables.(wood fires and seaside locations) If not that, a lucky guess might be the electros on the logic board.
