Your sys specs means processor model and speed, ram amount (and kind, if you know), and graphics card. If you don't know them, go to start, click on "run", type dxdiag, and hit enter. There you'll find that data.
Plugins... you must be using plugins to run epsxe. Post wich gpu plugin are you using and how is it configured (in the gpu plugin selection screen, click on "configure" - try to take advantage of the "copy settings to clipboard" button).
