Still working on 2004 Desktop, does not accept more than 256 memory, reformatted couple times.   Old computer needs to be cleaned the registry scan which makes the computer crash and slow ( and low memory). Still working fine for web surfing.

Took old laptop to Nepal on each visit. Lenovo with 3 gb memory 250 hd is working good since June 2010, downloaded free Norton Security System, advance system care and Security Essentials. Run once in a week to clean the registry. Working just fine.
