This happened just recently actually, when i was typing it would randomly throw letters after numbers and numbers after letters. I restarted. Same thing. I backed up my files and wiped it out. Now while im trying to reinstall windows (from a copied disk =X) when i push enter to install operating system and it goes to the recovery console, this never happened before, maybe the disk was bad. i grabbed a genuine microsoft 2000 pro disk and also hit enter and got the recovery console. i concluded that this is a virus that is not on the hard drive. i checked the keyboard, pulled off the keys, no problems there.

When i also turn it on it beeps about 20 times.

This was a really nice computer. I would really appreciate any hints, tips, or fixes to this problem.

Sounds to me like you have a failing keyboard, the random numbers and letters sounds like the Fn key is causing you problems. I looked on Dells website and you need to call for availability of parts for that model. Most Dell keyboards that I have replaced only cost about $10 plus shipping and tax.

If your pc is beeping 20 times at power on, it is failing the POST. You may have a bad power supply, loose connections within the pc, motherboard failure, etc.. Might unplug pc and just take a look see inside without touching anything. If it looks like you may have a problem with cables/connections, discharge yourself against the pc metal case for a few seconds. If you feel secure enough about leaving case off, try plugging in pc and doing a power on again. This is only a few things that may cause the beeping. From your post I understood that you were actually booting up until you tried to reinstall Win 2000.

Since you've reinstalled Windows, try updating your drivers and see if that will cure your touchpad/trackball problem. You might also check in Device Manager and see if you have any yellow exclamation symbols.

Big update, i pulled my computer apart and sure enough, the part of the motherboard where the keyboard and mouse systems go is corroded =\.

I guess im screwed.

Checking for a replacement motherboard, if its not cheap im going to junk the thing. All of the components on that part are gone

Thanks for your help guys, it's appreciated

Kinda figured it was something like that. If you can get yourself a nice anti-static brush and a can/bottle of circuit board cleaner, you might recover the PC by cleaning the corrosion out. I use to use freon, but don't believe that's normally available. Might find something at Newark.com under Chemicals. Check local electronic stores or, lastly, Radio Shack. It must be residue free, non-corrosive yet dries quickly. If you do all this, be sure to clean fans and heatsinks.
