Hey everyone... here's my issue. My dad has a HP pavilion thats about 6 years old (p4 2.53 GHz, 1GB ram). Recently, the computer has been slowing down to an almost unusable speed (it takes about 1 min to boot up, then another 10-15 to be "useable"). There's only needed programs on startup (antivirus, etc.), and the computer was wiped and XP reinstalled less than 6 months ago, so its not the Windows Half-life syndrome (It's also frequently spyware checked, defragged, etc.) And, with the exception of the harddrive, I know its not a failure of something hardware wise, as I run Ubuntu off a second harddrive on the computer with no problems what-so-ever. So i've narrowed the problem to one of two things: 1. Antivirus. He presently has Norton Internet Security 2007. Could this be causing the slow down? If so, what is a good PC antivirus I can look at getting him for x-mas? 2. Hard drive. Is it possible that the hard-drive is going? Is there any way I could verify this? Any other ideas would be great too... thanks!
