|As riider above stated, you should bench test the motherboard BEFORE installing it in the case. |
The procedure to bench test is as follows:
Power supply can be installed in the case. Board setting on insulating material like the box for the board. Install ONLY the following:
motherboard speaker - CPU/heat sink/fan - 1 stick of RAM - Graphics card or onboard if available.
Connect ONLY the following: 24 pin power connector, auxiliary CPU power connector, CPU fan to CPU fan header, power connector/s for Graphics if required, monitor, keyboard. NO case to board wiring, no hard drive, nothing else.
Start the board by momentarily shorting the two power pins on the motherboard. If all is well you should hear a single beep and the monitor should show POST screens. The computer will boot to a screen indicating there is no bootable media or something to that effect.
If this happens you can then install the board into the case and repeat the start up. As the steps are performed you can continue to add things. Next would be the additional RAM. Then the case wiring, then any additional add in cards, then the case wiring, etc.
There should be no real reason to flash the BIOS unless the installed BIOS doesn't support your CPU or RAM speed. If you buy a board with an older BIOS that doesn't support your CPU choice it may or may not even start up.
