I'm running an emachines T6212 with 2.5 gigs of RAM. (AMD Athlon 64 3200+ / 2.0 GHz ) Windows began slowing down a while back, so I reinstalled it after a format and fdisk. Even with a fresh install it can take about 30 minutes to get to something that resembles workable, even at that point the system lag is incredible. I did a memory test and all checked out OK. Thinking I might have a hardware issue I installed ubuntu on a second partition on the same HD, it flies. I've even swapped out the HD at one point but that wasn't the issue either. Any ideas/suggestions?
