For a PC, I would use the recovery disk and start all over again. The recovery disk will erase your entire hard drive and load and install all the original programs that came on the computer. Then you will need to reinstall any other programs and updates.
For a Mac, I'd go to the nearest Apple store and ask them what to do.
In general, after a complete install, you need to install the drivers for your sound card and your printers. The printer driver is usually available on a CD with a setup macro. The sound card driver depends on your computer. If it is a lap-top, they are usually pre-installed with the recovery CD/DVD. If it is a desk-top, it usually comes with a driver installation CD. If you don't have it any more, all is not lost. Look up the user manual and find out the model of the sound-card and download on Internet the required driver.
Yes, it is a pain to do a complete install. It is less trouble, but more expensive, to install anti-virus software once you get everything goin.
