I was on my computer listening to music. While I was looking for another song the screen went black. A white message box outlined in red popped up, reading "Signal Over Range." I checked the wires and cords, making sure they were all connected, and they were. I can't figure out how to fix it.

I believe the max resolution this LCD can support is 1440 x 900 / 75 Hz. If you set your display resolution higher then that, you will receive the input signal out of range error. Your LDC turns off to protect it self from the invalid settings. If you can not change it back once your PC boots to windows, you may have to do it in save mode by pressing F8 once you power on your PC and before the windows loading screen starts. Regards,Chris
It shows out of range because the PC is sending out the video signal that is higher than the monitor can display, you need to set the PC video resolution to the native resolution: 1024 x 768 @60Hz. You can reboot the PC into save mode (hitting F8 key while booting up) then set the resolution to 640 x 480 (try 1024 x 768 if it allows you to do so), reboot and reset the resoltion to 1024 x 768 @60Hz.
There are a few things you can check.
First, try to see if the monitor cables are firmly connected on both sides (computer and monitor) no need to remove any cable for now just check the monitor cables (ends should be blue or white on both sides)
Then check if you got an imput button on your screen (like all TV and some monitors now has) This input gives you the choice between a few possible connections and it may be on the wrong one. Just cycle trough the input modes and I think you will have your image back.
If Still, you dont see anything, try a different monitor or try to connect your monitor on a different PC/laptop.
In fact blinking blue could be there because the monitor is awaiting a signal on the input it's listening. At worst it could be because your video chip/card dont send a signal to your monitor, could happen, but imo it's probably not the case.
this means that your screen settings are not compatible with the game. like 16 bit color to 32 bit color. set the screen settings so that you can play. Display properties would let u adjust these colors.
Most commonly, this problem is caused by an incorrect refresh rate setting. LCD monitors typically DO NOT support refresh rates higher than 60hz - and this is no exception. Try running the game in "safe mode" if it has one. Adjusting the in-game video settings should solve the problem, just look for a screen refresh rate or any video-related setting with a number followed by "hz". Set it to 60, everything should be fine.
It could also be that at some point the game changes resolution (this frequently occurs if there is an in-game movie or cut-scene). In this case the resolution settings for the in-game movie might be at fault, check them if you can.
There may wrong setting of refresh rate. Most monitors work at 60 to 70 Hz refresh rate. Above that they tunned blank screen or out 0f range message displayed. Also check the output video signal. Please confirm technical specifications from the documentatation of the monitor.
The beeps are probably BIOS beep error codes. Through a series of long and short beeps the computer communicates computer problems that occur early in the startup processes. It's likely the problem isn't your monitor but something in your computer box itself. If you can tell us what the pattern is we can start diagnosing your problem. We'll also need to know the manufacturers name, the specific model computer you have and what operating system you are running.
