Use Ctrl/Alt/Delete and go to the Performance tab to see if you are close to using all of your existing memory.
If you are, then go to
Control Panel | System to see how much RAM Memory is installed.
Then go to www.hp.com / www.dell.com... whatever and look at specifications for your specific computer - model number and/or other info... to find out how much more you can install for your specific computer.
You can buy it from the manufacturer's site... but it's usually cheaper to buy from egghead.com or similar.
