Hi, I'm not quite sure if this is the right section, as I am unable to determine whether this is a Windows or a hardware problem. I have recently reformatted and re-installed Windows 7 and have noticed that my computer is very laggy or stuttery. What I mean is it will run at normal speeds, then when I try to do something very simple, like load a website or open a program, it will suddenly freeze up for anywhere from 2 - 20 seconds, sometimes longer. Then I will be able to freely do things for a while. I thought it was simply spyware or something of the sorts, but since my hard drive was cleaned before re-installing, I'm not quite sure what it could be. It is possible that my second hard drive could have something on it, I suppose, but my scanners (Vipre and Spyware Doctor) did not notice anything on either drive. I thought for a little while that it could be a hard drive problem, as my hard drive is getting fairly old. I'm not quite sure what sort of information will be needed, but I'm more than willing to post pictures or anything of the sort that would be helpful. I appreciate any help offered!
