Both of my home desktops running XP PRO have just died in the past 24 hours. It started out being flakey yesterday. Dropping connection to my work every few minutes. Now I can still connect but I'm seeing 20 minute response. For example I wen to download one of those free internet optimizers and it said it was downloading at 300 bytes/sec. I've gone round and round with internet provider who says it looks fine from their end. Wher should I start? Maybe I picked up a virus?
