Well, using LSD and computing can cause some wacky experiences. Perhaps you're using an LCD? ;) (just had to, sorry)
What type of video card do you have? More than likely, there's a rotation option for it. Try right-clicking on your desktop background, and then clicking on Properties. Once there, click on the Settings tab. There should be an Advanced... button. Once in there, try to find a tab that looks appropriate, and play with the settings. On certain ATI and NVIDIA cards, there exists a tab just for Rotation.

It is almost certainly a display setting incorrectly set.
Bring up display settings as described above. Click on 'Settings'.
You will see a little picture of a screen and below it will be information about your display adaptor and your monitor. Tell us what it says please, so we can work out where the setting might be to change it back.
There's a chance that it might be the work of a silly little (but I'd have to admit, funny) virus, but let's eliminate the more likely cause first, eh?

If the settings have been changed there's already the appropriate drivers installed, so no real need to get new ones I'd consider.

Catweazle shuns all credit for silly little funny viruses, and is content to merely sit back and chuckle about them ;)
