What are System Resources?
This months column is about System Resources in Windows (unfortunately this topic is really geeky, so please bear with me!). There are many definitions to this question that can deal with things like IRQs, Com Ports, Memory Addresses and the like, but for sake of this column we are going to be using Microsofts definition from Windows. Some of the most common questions I get asked as a professional PC troubleshooter are about System Resources. Some of the questions are: • Why does Windows say I dont have enough memory to do this? I just added more RAM; shouldnt that have fixed it? • Why are my System Resources so low? I have more memory than everyone else? The first thing you need to understand is what exactly System Resources are. System Resources are a hold over from early versions of Windows. In Windows 3.X they were three 64 kb heaps of memory called System, User and GDI (for Graphics Display Interface). Unfortunately the sizes of these heaps are limited and adding RAM wont help. Mi
