nVidia overclocking problems

[Dudeman591]

Knowing the GeForce 6600 is now out dated doesn't help much. I have one installed in my dell XPS 200 and it worked fine for like the first month after that i had a fried memory card screw up my whole system and ever since then i have tried everything with my clock frequency settings and to get them running good again but my counter strike source will no stop lagging. Ive tried to restore defaults, detect optimal frequencies, and tone the MHz down but that hasn't worked either so now i'm post here lookin' for some helpin'-plz-for god's sake
