Yes, that is extremely low resources, my computers is tuned to run at 96%. You must have every program on the start up menu running, or you have a virus. I am a little more that a beginner, but the following may help. This is pretty basic, but hit control, alt, and delete buttons at the same time , and you open the close programs windows. This tells you which programs are loaded from the start up menu when you boot up. I will assume that you have OS 95/98/or ME. These programs run in the 'background' and don't show up on your taskbar, like when you open a program. You want to clean up what is loaded. You probably want to get rid of everything except explorer, sys tray, and maybe your printer program if you have a printer. To stop these from loading, go to the start-up menu. One way to get to it is by clicking on the start button, run, and type in msconfig in the box. Open the start up tab and delete the items that were previously viewed in the close program window I just mentioned. You might want to keep anything that has to do with power settings if you have standby mode enabled to save power, and also keep anything that has to do with registry, and printers. Write everything down before you start unchecking in case you delete something that you shouldn't have. The best way would to be to delete one at a time. Unchecking some items will prompt a reboot to take effect.
As you are proceeding, right click my computer, hit properties, and click the performance tab to check you sys performance to see if it goes higher as you eliminate unnecesary programs from loading. I'm not sure about the way you described your RAM, I don't think that you have a Gig of memory. The normal amount of RAM is usually, 32,64,96,128,256, etc. MEGABYTES not GIGABYTES, depending on the amount of SIMM's or DIMM's installed. For future reference, describe what operating system you are using, (Win 3.1, 95, 98, ME, or 2000. Hope this helps some.
