Os XP. About a week ago I had about 30% resourse left on 20g c drive of a older computer. and downloaded about 40 pics and I downloaded adobe acrobat reader 8. I checked my resource and and I was very low down to 150mb and was getting alerts. I deleted about the same amount of pics as downloaded and checked again and I was still about the same, resourse keeps going down not up when I delete stuff. I checked virus spyware and all clear. How am I using that much resourse?
