My Dell Optiplex Gx 620 isnt turning on..... No lights no sounds is it the motherboard
Bad power supply first, or just the switch. The mother board will keep it from posting, but lights should come on. a bad power supply or switch it will be dead like fred.
If your handy there are many tutorials on diagnosing a power supply on the internet. Usually when it is the mother board there will be a few beeps or flashing lights then a shut down, or frozen pc on boot then death.
But all these symptoms can come from a dead or dying power supply.

Same problem here. I've cheked everything. It won't start. Had the mb to service but it only worked for a few days after that. Problem starting the pc after turning off the pc. Rebooting went vell. When starting the pc from power button notting happened. even took out the power cord. Now the mb is at service again and it has been there for a month now. not good bad service
