What does error 4ROM/4/40000000 mean? How can this be fixed?
When powering on it gives one long beep and then fails to boot. It will spin up attempting, but doesn't fully engage. If I repeatedly hit the power button it will eventually boot up, but it takes four or five attempts. I know it's not the RAM and disk utility found no problems. The hardware test, short and extended, both resulted in error 4ROM/4/40000000. I'm wondering how bad this is and if I'll need a whole new motherboard? Basically, will it cost enough where I should consider a whole new computer?
