Sceen and mouse virus help...

hello all, i`ve posted this question on a couple of other useless forums with absolutly no answers, please help.

i own a hp laptop running XP HOME,

Every time i turn my comp on it goes to the hp graffic with the cursor, i can move the cursor but nothing else, just stays on that screen no matter what i do...i`ve tried safe mode, last known that worked ect and still get the same outcome...hp graffic with movable cursor

i have also tried holding down shift until it beeps but nothing pops up...

I`m preety sure its a virus that i`ve picked up!!! is there any way to get rid of it and make the laptop work again without having to reinstall and lose everything?


can anyone help please?
