i bought new parts for it

1. did you buy them to attempt to fix your system? or...
2. did the problem start happening after you installed them? and if so, after installing which part did your system start rebooting?

-also it helps to specify your system specs (brands and model#'s) when asking a question like this so we can verify compatibility/conflict issues. you need to be more specific about your components than "512mb RAM"
