Hi all,

i have an e6400 latitude, and it was working fine till yesterday when all of a sudden i was getting sluggish response to everything i do, from opening programs, to editing word documents. So i restarted and the computer gave me an error about not finding a boot device, so i played around the bios a bit (red stuff online) and managed to get some life out of harddisk. And it seemed to be working fine, but it tends to slow down (be sluggish) and then be awesome again, it like its coming in waves. What do you guys think the problem could be?

thanx for your help!
