Looking at a Sony Viao, not sure what model. It's a 2006 if that helps. Anyway, the problem is it is running very very slow and I think it's the HDD. It's only an 80gb HDD, not that that matters but I'm sure it's 5400 rpms. I don't think the processor or anything is messed up because when I check under my computer properties it still displays the dual core processors with 1.73. It has what I think to be 2 gigs of ram or atleast 1. Like I said I'm not sure but the computer tech that looked at it said a virus had eaten up the HDD, is that even possible? Anyways, if it is the HDD I took it out and looked at it. It has a connector built onto it. I don't know a lot about laptop HDDs but do all 2.5" come with this connector? If they do I should be able to buy anyone right? Well, if you have any other suggestions about the problem just let me know. Thanks a lot.
