hi guys i got a lap top hp pavilion ze4500(AMD athelon xp-m- 192 mb of ram and 1.79 ghz )and it orginally had windows xp home edtion . Lately i put windows xp pro inside my lap top and upgraded it to windows xp pro service pack2 .But now it is dam slow! My lap top starts and turns off very slower then before. Many friends suggest that i go for memory upgrade. I want to ask you guys if this problem can be solved by memory increse?Furthermore,is it easy to increase the ram if i purchase the right RAm or do i need some expert to do it for me.Do i need to add extra memrory to what i got or replace the 192 mb with bigger one ? What memory size your guys suggest. I be happy if an expert give me some suggestion.Thanks
