I cannot find any data on beep codes for this model? What are the Diagnostic LEDs during the beeps?
When turned on. Click the link in my previous post.
Not really. I would start by disconnecting everything from the motherboard (cables, drives, cards, ram, etc.). Then power on with only the CPU still installed. See if any Diagnostic LEDs appear. Then add the ram, power on, check the LEDs. Keep adding hardware back one at a time.
