Reload mistake

Hey, I've reloaded OS's in the past, but it's been years. I thought I could remember how to do it, but was wrong. Anyhow, I tried to reload xp sp3 because I had a virus I couldn't get ride of. When I did, I did it wrong. I copied over the existing OS. I then realized it and looked up the proper steps and tried again. Now my computer won't recognize my monitor's driver or really any driver for that matter. It won't let me run my att dsl set up disk. I am looking at a 4 bit screen and can't seem to figure out what to do. Am I done for? Do I need to try a fresh reload again or what?

 

thanks. I'll have to check that out.

 

My motherboard is a Compaq sp#283983-001. Where can I download the driver?

 

Before I tryed the reload. I saved my driver folder on a jump drive. I've downloaded the driver folder onto my c drive now. I've looked into the chip set folder, but their are no exe files. Any suggestions?

 

I downloaded the driver from that site. Everything is acting like it should now. Thank you both.

 

Ok, my computer froze up last night. I turned it off. Now it won't come back on. I can hear the hard drive coming up. I've tried a different monitor and cord. I plan on checking to make sure I have the right amount of voltage coming out of my power supply. After that I'm not sure what to check next. I just have a feeling that my mother board is toast. It doesn't look like it or anything. I'm just guessing. Any ideas?
