Page 1 of Double imaging on programs!

Ive recently been trying to use my digital camera but when i loaded the software from cd rom i couldnt use it because it was putting a double image on the screen. I dont know if this is due to a virus or anything like that but its definately not the software because i borrowed somebody else`s cd rom and this did the same. Do you think that it could be my hard drive. Ive run a thorough check with scandisc and this found nothing. Anybody pleeeeeezzz help me !!!!
