Well the 20-pin PSU started the comp up, but there was a warning in big red letters that a 20-pin PSU was being used instead of 24-pin. I was also unable to even get to windows as the system couldn't boot and showed an error message stating that there is a hardware problem. As I stated earlier, the mobo manual said that using a 20-pin PSU could cause the system to become "unbootable or unstable due to insufficient electricity". I bought an adaptor for $10 online, but my one question is:
Will this new adaptor really solve my problem?
And one more thing...
I have never booted this computer up with this PSU or mobo, and I have a brand new Radeon 9800 pro inside without its drivers even installed yet.
Should I use my old Geforce4 MX460 while i'm booting up the comp with this new mobo and install the mobo's drivers first, or am I ok using this new graphics card and installing its drivers after I install the mobo's drivers?
