You don't want to join a pool? I'm able to mine up 8 LTC / day on a pool with my simple setup using CGMiner. Solo mining didn't sound terribly profitable unless you can throw lots of hashing power at it.
i can make around 15 to 20 a day in pools solo I can make maybe 2 to 3 blocks a day if lucky so that's 150 liteocin compared to max 60ltc for them days but I do a mixture so I mine some cards on solo some on pools
Sounds like you should stick to the pool until you can narrow your problem down. Averaging 60 is better than hoping to get "lucky" with 150.
Obviously there is no guarantee but I feel this will be more profitable in the long run while mining is still producing good outcomes.
