Right now I am at the school library.

Yesterday I was at my house, and I wanted to change the resolution on my computer. I wanted to make it so I could see more on my screen. I did this and clicked "OK" and then my screen went BLACK and stayed that way.

The screen was still on, and I heard sound effects, so the only problem was that it wasn't showing what was on the desktop.

I tried pressing enter to see if I could cancel the resolution change, but it did not work. So I restarted it, and no luck. I really have no CLUE what to do, and at the MOMENT my family nor I can AFFORD to get someone in.

I have an HP, I don't have the stats with me though, sorry. We're using Windows XP.How OLD is the computer?

Can you test the monitor out on another computer to make sure that it's not the monitor thats died...Whats the full spec on your system.... im running a HP system myself ....Reboot the computer and go into safe mode.  When the computer is booting hit F8 see if you can see anything in safe mode sounds like when you were changing monitor resolutions you went out of range ofyour monitor.
