Hi! I am having a problem all of a sudden when I go from one page to another or one folder to another then use the back button (Internet Explorer or folders on computer) it starts jumping back forward to where I was and will not stop. I cannot go back. I have tried putting things on different HDs but the problem is still there. I have 2 internal HD's a 250GB and a 400GB. I have 1 external 500GB that I access quite a lot. I thought maybe the 205GB drive was too full, but removing things still did not help. the 250 GB has by Windows XP on it. I did a disk defrag and that did not help. I have googled this question but no help there. I have 2 gig of ram and a 3.41 GHz cpu. I have had the computer about 3 years. Would appreciate any help as I don't know what could be causing this! Thanks!
