Hi, my pc was being really slow after my daughter accidentally downloaded a software program (Windows Messenger) so I decided to copy out my documents and re-install everything again using the disks that came with my Packard Bell Imedia 3063. I now have a lot of unexplained hard drive activity and the little yellow light on the front of the pc intermittently flashes on and off for no apparent reason when the pc is not being used. My pc is running Windows XP with all updates and Norton 2009 is my anti virus software program. Can someone offer any advice / support? Regards Ticitybo
