Upgraded from PS2 to PS3 so now wanting to sell PS2, problem is it switches off randomly sometimes.

Im wondering if its the cords or the yellow power pin thing. Cords look fine however there is a bit of a bend where some of the black cord is torn and no signs of burns on the power connector thingy.

Im wanting to sell on Trade Me, was just wondering what I could start my reserve at, and also do I list with controller and memory card or sell them separately.

TIA.
