To be honest, you need to just go buy a Dell or HP. You dont accept anybodys answer, you just reword the next question, so all your threads become a vicious circle, over and over and on and on.
Everybody here has told you over and over what you need to do.
Like the power supply question. Fatback told you which ones were the best, 87dtna told you out of this list which was the best. Then you come back and ask questions about the one that was said (Maybe) might work.
You were told many many post back that a Power Supply and Video card was your best bet.
A GTS 250/4850 and a quality 500/550W power supply. Antec/Corsair/OCZ/Silverstone, any of these will work just fine, doesnt matter!
