fix computer errors

I was browsing the internet and I was just looking at a post and all the sudden my computer froze up and these pop ups from the xp kept popping up and I couldn’t do anything. Its probably a virus but I restarted the computer but I keep getting this blue screen even in safe mode. Is there a way to save the system and return it to the way it was without having the wipe the harddrive clean?
The Blue Screen says:”
A problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time you’ve seen this stop error screen, restart your computer. If this screen appears again (which is does; safe mode or not) , follow these steps.
Check to be sure you have adequate disk space. If a driver is identified in the stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adaptors.
Check with your hardware vendor for an BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select advanced startup options, and then select safe mode. (already did – nothing)
