Your cpu and gpu both are very weak for liteocin.Some days ago I tried mining tagcoins with my dual core E5200.But bth the processor and motherboards temperature were at 99 degree celcius.You can use your cpu to learn the setup and see hows its like to mine,just to learn.And keep a look at your temperatures.
