some of the drivers that comes with xp are currupted and i dont have a roll back. i was unstalling a data recovery program and when it was uninstalling it currept a few other drivers. my sound river gives trouble at time and i have to use system restore, the cd rom drives are currupted so neither my internal nor external cd drives are any good and my serial mouse driver is disapeared. i cant find any drivers to replace them. the onlyalternative i know of is to format my hard drive but then i would loose all my information. any help or advice would be deeply appriciated
