whoever is giving you pc advice, dump him and find someone else, he's giving you bad info.
you are having trouble booting, nothing to do with games.
I tried today with diffrent power supply and was the same issue.
-I replaced the Mob and graphics card from the comapny and now whats happening is after i install graphics driver it stucks on windows logo screen.
-Without the graphics card driver it works fine.
-My IT guy says i need to change the motherboard to intel chipset or Asus ...???
-Is this the correct solution?
Please advice, thanks
