Screen Reselution stuck?

Ok, I reformated my pc using the Cd that came with my computer. After it did it's job and I logged everything is huge (screen reselution) so I went into control panel to change it and the slider bar is stuck. How can I make change this. Also I have been told to change my monitor or something like that and I can't acess or change any of the monitor setting under advaced settup in screen reselution? what it the deal.

Please if you know let me know I have spent hours going through things and changeing things and nothing has worked.

thanks!

When you go into Device manager to check on your internet driver problem, more than likely you will have a explanation point next to you moniter in device manager also. You are running the generic driver Windows uses is why you can not change screen resolution. The driver for your chipset for video also should be at your computer manufacturers website when you are looking for you drivers for your internet card. Follow Bk's instructions after you have downloaded the driver and installed it.
