a little late, but i figured i would post a follow-up on what happened with this issue. i found out that all of my USB ports were not functioning, so i uninstalled all roots and then windows reinstalled them on start up. i thought this would solve my problem, but the keyboard still was not functioning. it was strange because the keyboard would function in BIOS before windows xp loaded, so i was able to startup in safe mode but the keyboard still would not work in safe mode. any keyboard i used, ps2, USB, wireless, always came up with a code 41. then i figured i would try to system restore to a point when the keyboard was functioning. my PC refused to system restore to any date. every time i tried it, upon restart it would say the restore failed. so i basically ran out of options.
just today i reformatted the entire computer. i feel lucky to have a dell because the newer dells come with a dell PC restore option, so all i had to do to return the computer to factory settings was hit ctrl + f11 on startup before windows and the entire uninstallation reinstallation process took about 10 mins. of course i lost all personal files but i backed up the things i wanted before i did it. restoring to original settings was the only option i had left - what good is a computer without the keyboard?
i still don't know what caused this problem. i have heard that windows xp and vista have known problems about usb conflicts, so it might have just been an inevitable problem to happen. i also know i had a trojan on the computer that i am pretty sure i removed, but it might have disabled the system restore which would explain why it failed each time. basically, who knows. i am just happy to have a functioning computer again!
also, if anybody responds to this, i am looking for a good antivirus program for this computer. i have had problems with mcafee, trendmicro, and norton getting viruses on my computer. i have heard good things about AVG, so i might try that next. any input about that?
