Why does iMac boot up with just one memory in any slot?
I bought an iMac on ebay. It has been completely disassembled at one time, the warranty sticker is gone. Damaged sockets but still functional. The problem it has is that it will only boot up with just one memory in any slot. With two memory sticks it will try to boot then restarts and all over again. Same with 3 or 4 ram. Is it software related?
Also this iMac had power supply from 2009 27" iMac with couple transistors burned but still worked. Now it has proper power supply. Could the logic board be damaged by that power supply?
Is this a good question?
