Computers these days come with a recovery partition that can be used to restore it to factory settings. The procedure should be documented in your user guide, which should be on your hard drive. If you don't have it, you can download it from your computer manufacturer's web site.
When you've gotten your system back like you want it, I urge you to get yourself an external hard drive and a good 3rd party backup program. You can set it up to do everything automagically at the time and frequency of your choice. 1.5 TB external hard drives are about $90 these days and a really good FREE backup program is the Easeus todo backup free which you can download from
http://www.todo-backup.com/products/home/free-backup-software.htm . That can save you a lot of time and frustration the next time something like this happens. Sooner or later it happens to all computers for one reason or another.
So i've tried everything TRUST ME!
I was wondering if any one knows where I could download XP again?
I didnt download in the first place (it came on the pc) but maby i could reinstall?
