Optiplex 390 SFF bad memory slot??

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?

Then Slot 2 might be the primary one, and have you tried memory in BOTH Slot 1 and 2?

If you populate both slots no boot.   Either stick will work in slot 2.
