Take the side panel off.
Reseat all the cards/plugs/ram.
Look close at the cpu hsf to make sure it's not loose.
I use a dell optiplex 9020. 8 gb ram, 500 GB HDD
Recently i moved between countries hence sending my pc in cargo
Once i switched it on in the power button
An Amber color light blinks in the pattern 2,3
I looked it up and it said cpu/motherboard/ram issue
any suggestion on fixing it????
i dont want to send much money.......
