Well, for starters, your processor isn't dual core, so don't check that box. Processor could be better, and you only have 32 bit so the emulator already won't run as well as 64 bit.
That aside, your RAM is a huge cause as well. 1GB is very small. (I've had worse, 448MB of RAM, and that was hell with Vista)
If you can upgrade RAM (which is relatively cheap now), try it out again after getting another GB.
