Kinda of a rookie question, but i just installed a new CPU into my brothers old board. It starts up fine, but while in POST, gives me an error and tells me to go into BIOS and to reset the CPU settings. So I go into the BIOS look at stuff, then the computer just shuts down. I have to turn the power supply off and then back on in order for it to boot up again. I keep getting the same error, i tryed going through the BIOS quickly and then saving and exiting, but when i exit BIOS the computer shuts down and i have to reset the power supply. I also installed a graphics card, idk if any of these could contribute to the problem but i would like to figure out what is wrong without paying a professional to do it for me. Thank you.
