you should narrow it down.
If you switch to runlevel 3 ("init 3" or shutdown your x-session), can you successfully log in as root? if you can, can you switch to root from another user (using the "su" command)?
If both works, it has something to do with either the program you want to run or the tool that runs this program as root. I doubt it has something to do with your memory (if you HAVE a swap-partition). Just as under windows, the system is "pretending" to have as much physical memory as your "real" memory and swap partition have together.
If switching to root fails in the console, it might be some problem with the passwd- or shadow-file. I can not help you from there, as I also only am a beginner - but I am sure, someone else will have a solution.
