upgrading dell gx280 (g8310 & n4846) motherboards

Hi

dell have a good support system on line
You either enter the model or better still the serial number to find drivers & bios update programs & user guides & service manuals

You only upgrade bios if it cures a problem you have or want to upgrade the windows version as there is a risk of bricking the motherboard if the power fails at a critical moment
