N3 very slow startup - hw problem?

I bought N3 and install for test my old computer (normaly i going to install it on new Notebook). My system is AMD 3000+ Ghz, 2GB Ram and 120GB 7200 speed HDD. My problem is: when i start program the windows with activation sw starting up long time, then i fill activation informations and start program. Program start up is 5 - 15 minutes. Is it some hw problem or i have very low requirements? In minimum requirements is 2.4Ghz Pentium 4 and 1Gb ram.
When N3 start up, evrithing is normal, program run perfectly. Only if i go to setup score the wait time for display setup score is long - maybe 15 - 40 seconds.
