What can i do to fix my P.C?

My PC's colour settings seem off but I can't work out what's wrong, or fix it. Help?

• My settings seemed perfect yesterday, but I've been messing around getting my Xbox to work on my monitor, so I have messed with all the settings to best fit my Xbox. But now I have gone back onto my PC and it's all wrong. I have changed all the settings back, the resolution is right and my colours just seem wrong (maybe too saturated), and a little bit fuzzy. I have messed with the hue/saturation and that doesn't do it. The auto adjust doesn't work either for some reason. Anyone had this problem, I just can't use my PC like this, and my college course really requires that I cane use Photoshop etc. and I can't really do that with this terrible image quality.

• Answer:

  I suggest you use the System Restore operation to restore your computer settings to an earlier date when it was working really fine. This will certainly clear away all the mess you created as you tried to change the settings. Click on: Start > All Programs > Accessories > System Tools > System Restore, from here, you can select an earlier date in the past (normally any date before the problems started) and click on it to start the System Restore operation.
