I get this solid amber green on my dell optiplex 380, I have tried everything and failed everytime. My powersupply is working fine, I switched my psu into an other pc I had and it worked just fine. I replaced the cpu, reinstalled ram, replaced ram, re-installed CMOS, checked Harddrive and it worked fine, Checked to see if all the cables was in places e.t.c but still no hope which leads me to think that there is some issue with the mobo. I might be wrong though. Your my last hope Linustechtips, what should I do?? :3
