error code confusion
On my optiplex 790, i get the code 12 4 then 3 then 12, if it starts up normally it will flash some other codes then go to nothing and start up normallly. if it stays at 1 2 blue power light, it will stay then beep and stay at 12 forever with no display or anything. Sometimes the pc black or white screens and upon rebooting, it goes to the 12 loop as mentioned before. I am currently testing other things such as mobo or psu failures and want to exclude an issue. is there anything i can do to fix this or is there any causes for this. i have heard the lights for older systems can be unreliable. it would be greatly appreciated if someone could help out.
