UNABLE TO USE WINDOWS XP

Unknown

Hi all. thought i would give this great site a try as i have a major problem! i'm running windows xp with avg(free edition) spybot and ad aware. i firstly had the screen picture changed by something telling me i had spyware on my computer and to click the link(it was black and yellow). i never did click the link and tried to remove it myself but failed. second problem was yesterday i turned on the computer and i had a message stating that something had been changed and windows would change it back, i thought this was a trojan and pressed no( it gave two option yes and no). after that the origanal back drop(instead of the spyware message ) came on and that was it, nothing else. no file folders, no task bar along the bottom. the mouse worked(although i had nothing to click on!). i could open the windows task bar(ctrl+alt+delete) and that worked. (sorry for my lack of knowledge, i am not very computer wise!). i attempted to open windows using safe mode, but when it opened, all i got was a black/dark gey blank screen with safe mode in white in all 4 corners with windows xp etc in the top center. no folder or anything again. i then tried the debugging mode(grasping at straws at this stage!) and it came up with a blue screen saying> unmountable_boot_voloum
and then at the very bottom of the message>
