I bought a new computer and was surprised to see: 800 mb available out of 2 gb.
How will I stop this from happening?
I don't want to disable Aero Theme,but I will,but not all,only some features of it.
Well, first, you need to find out the program or source of what's hogging your system resources. Programs you can download for free (search on Google) will be able to identify what services are running.
why would you download a program that takes more resources when you're trying to find out what's taking a lot of resources in the first place? it's called task manager and it comes with windows.
second, i agree with gorman, google is an awesome tool.
