Question about Dell Optiplex GX280 (99301) Motherboard
POST ("power on self test") codes for the Dell GX280 are in a format of n-n-n as in 3-1-2. This would sound like 3 beeps, followed by 1 beep and finally 2 beeps. If you're not paying attention, that 3-1-2 beep code could sound like 6 simple beeps.
Dell has a page for the GX280 dedicated to Troubleshooting Tools and Utilities. There's a great deal of information on it - but the POST codes you're looking for are explained in detail about mid-way down under "Beep Codes" This document and associated links should go a long way to help you properly diagnose the problem with your GX280.
