It's not technically difficult to do.  The hardest part is finding out 
what memory modules to purchase that will be compatible with your 
system.  If you know what make/model your system is or the make/model of 
your motherboard and CPU, we can give you specific suggestions.

Basic steps:

1. Power down the PC
2. Unplug the unit from the wall and all other devices
3. Wait a minute for capacitors to drain (there should be no lights on 
inside or fans spinning, etc.)
4. Open the case, repeatedly touch the chassis to discharge any static 
electricity (or stay in constant contact with the chassis during the 
installation)
5. Remove the old RAM chips (if needed to make room for the new ones)
6. Install the new RAM chips
7. Close the case
8. Reconnect peripherals and power
9. Boot back up and watch the startup screen

The only time I've seen problems is when you have a bad or incorrect 
memory chip.  In which case the memory chip may act up in various ways 
(including smoke).  But that's only something that I've seen once or 
twice in the past 5 years out of dozens of system upgrades.

Usually the worst-case scenario is that the system won't boot until you 
put things back the way they were.  Or move the memory chips around so 
that the system is happier and less confused about the configuration.

Of course, if the system is under warranty, you may want to talk to the 
company first to check whether user-installation of RAM will void any 
warranties.
