i need help...

I have windows XP. A few days ago i restarted my comp and when it came back up i had no audio(it says there is no audio device), no printer(when i try and add a printer it says operation could not complete, and that i know of, system restore doesn't start.

I have tried getting help from other places but still nothing. I want to format the computer to how it was when i bought it using the cd that came with the computer. When i put in the cd and restart the computer it boots normally. The boot order in bios has the cd drive second after the removable disk. When i got the computer it came with windows ME but i upgraded it to XP.

Here are some things i remember doing before i restarted, but i rarely restart or turn off so it could be from a while before.

I installed new drivers for my video card, but when i had the problem i rolled back the drivers to the old ones. I downloaded some security update from microsoft, but i don't think it ever installed.

I did uninstall a game(Tom Clancy's Splinter Cell) demo and when i did it said "Some system files have been changed. Please insert the Service Pack 1 cd to restore them to normal" or something. I don't have the SP1 cd so i downloaded it online and when i tried installing it, after downloading files, it stopped at creating a restore point.

Also i installed a audioc codec(ac3 digital).

I think thats it. If anyone could tell me how i can format it to before or fix the problem, pease help.

Thanks

 

I just remembered something and i think its whats broke the comp.

I went into msconfig once to change the startup and while i was in there i changed some settings. Like i turned off some microsoft programs that i didn't think were needed from running but i never rebooted after that and i think thats what cause the problems...but... Now when i go to start>run>msconfig it says it can't find msconfig.

Is it called something else and is there some other way to get into it?

 

Go to start...run... type cmd
Then type scf /scannow ... have your Win XP CD at hand in case it finds any issues.
