Normally when I start my PC my Ram usage is about 320Mb out my 512Mb. So this is what I do to save my system resources. Note, I am using windows XP. After I am done, I end up with a ram usage of only 150Mb-170Mb out of 512Mb.
1. I keep a separate XP User Profile to play games. That way I can totally tweak it to save as much ram to play games.
2. First I clean up the unwanted start up programs in my new user profile. I use the Microsoft Autoruns tool. In it I remove ticks from all the the startup programs i do not need to play games like 3rd party software. Eg: adobe updater etc....
If you are using an ATI graphics card and you have the catalyst center installed, you will be able to see it running in the background from the task manager. It's process name is ccc.exe and there is another process associated with it named mom.exe. You do not need either of them to play games. It is there just to open the catalyst center. It alone eats about 25-40Mb of ram. I always stop both ccc.exe and mom.exe processes when playing games. You can also find the Catalyst Control Center service in the Autoruns tool and remove it from start up programs. When you want to access the catalyst control center again just tick it in the Autoruns tool and restart the PC.
There are a lot of stuff not visible to us even from the task manager. But do not remove drivers and things like that. What I do is I look down the column of the manufacturer. I keep all the ones from Microsoft and remove other stuff that I already know about.
After that I restart my computer. WARNING. Removing System Programs can cause problems. Therefore when you first open the Autoruns Tool, Save the configuration as default. Then change the startup programs and if some thing goes wrong load the default file.
3. I also stop my virus guard as it takes about 100 MB of ram. Mine is Kaspersky 2009 and I stop its protection and then close it.
4. Then I use a software called Memturbo 4. It can defrag, free and optimize your ram. It has a lot of other functions that helps to speed your computer. It is very good for gamers. I always defrag and free more ram before playing any game.
Well that's it. After I've done all these, my ram usage is only about 150Mb.
