Problems with FSX

Before I begin, I'd like to inform you that my PC is a 3.2 ghz, 1GB Ram, 300GB HDD, 256MB Ati beast! And is almost brand new.
To me anyway, FSX isn't as good as I thought it would be. It takes me an age to load, the frame rate is rubbish, and there are bugs in the game. One example; sometimes, my comp randomely re-sets (without going through the "saving your settings" and "windows is shutting down" rubbish) and I get "system has just recovered from a serious error" error report prompt. The graphics are top notch, but its too slow, and takes up too much HD (not that my HDD is too small of course!)
Does anyone else have problems like these? I think the game may have errors in it?
