I cannot get any memory stick (tried 2gb and 4gb pc3-10600) to read in slot 1. The computer refuses to boot and stalls at a black screen immediately if any memory is installed there. If I just put memory in slot 2, no problem. I cannot see any visible damage to slot 1 and cleaned it with contact cleaner. Is there anything else to check? I had bios A09 and then upgraded to A14. CPU is an I5 2400. Thanks!
So if you put a single memory stick in slot 2, the machine boots fine. But if you move that same memory stick to slot 1 (slot 2 empty) it fails to boot or enter BIOS?
