  1. Could you be a little more specific, is it laggy or does the game just crash?
  2. Really laggy it does not crash but so laggy

    22A on the +12V rail? That's like 264 watts on the +12V rail. Which is where your graphics card take the power from. It maybe too low, but since you don't crash it may not be a problem. But worth a try to check on how the card works with some better power supplies (To be serious you are very smart putting the +12V rail there). Another reason is that you don't have the latest drivers for your computer.
  4. i dunno it just says that its max power is 500watts and so one im not good at powersupplys thats my weakness on pc's and heres something whenever i plug my other H.D.D it doesnt give me an error on start ups line No Master IDE H.D.D detected but when i plug my video card yes it gives me that exact error i dunno whats the prob ? well im low on my buget i got like 28$$ lol
  5. im not sure at 22 to mybe lower i guess cuz 22 the highest so i put there im really a noob at this. and im using SATA on hard drives.dvdrw-rom :(
