I had a problem with my optiplex 780,i reboot it but i began to blink on power button i also saw 1&3 blinking green i Later replaced my CROM battery 2023 but the issue wasn't resolved i open the case removed all the drives from the motherboard i started reconnecting one by one but it didn't work todat i openned the case and removed my proccesser and guess what!i pushed the power button and the funs began to run the led light on by PSU displayed green and the power button yellow without blinking i also noticed thata green blinking light on 1,2 and 4
my question is could it be the processer causing the issue?
i replaced my RAM old (2GB DDR3-1333)with (2GB 1RX8 PC3-10600U-10-AO 1333) but am still getting the same beep code 1&3 (blinking green) with a yellow poor button.nothing else work the funs aren't running,the test button on the back of my psu has a light which doesn't turn on
i tried removing my Cpu processer (INTEL E8400 CORE 2 DUO 3.00GHZ/6M/1333) i turn on my Desktop and everything runs the funs run the green light on my back of my psu lights Green the power button lights solid yellow while the deep 1,2 and 4 blink green

1 3 is bad incompatible ram
1,2 = A possible expansion card failure has occurred.
2,4 = A possible graphics card failure has occurred.
