    would love to....but....again, the PC does not even start up. It displays the message and then just sits way before it goes into its boot sequence

    >>>t goes into its boot sequence>>>

    What error message or what result do you get at the end of this boot sequence? Jack E/NJ

    I power on the PC, it immediately displays the DIMM1 and DIMM2 not the same message. And then just sits there. nothing....else. Can't press PF2 or any other key to get into the BIOS or anything. Does not display the ACER logo....nothing...dead....

    Your mainboard Z5WAL LA-B211P uses low voltage 1.35volt DDR3L modules. Accordingly, I think that a high voltage 1.5volt DDR3 module and a low voltage 1.35volt DDR3L module were mixed on the mainboard sockets. This helps explain the BIOS error message DIMM1 and DIMM2 are not the same. The BIOS then halts/stops and won't proceed to the ACER logo. This not-the-same error message apparently still remains in the BIOS memory even though you removed the new module. I suggest that you remove the BIOS RTC/CMOS lithium coin cell and short its terminals on the mainboard to try to re-set the BIOS chip to a default state. Jack E/NJ

    ok, now I'm confused. I didn't change anything. Didn't try to add any additional RAM, So how could there be different modules all of a sudden ?

    Sorry, this thread has been somewhat confusing due mainly to the questionable mainboard identification and its two replaceable memory sockets. My guess is that whatever RAM module is in there now has failed and causing BIOS issues. I suggest that you replace it with a new low voltage 1.35volt DDR3L 8GB module which this board apparently uses. Use a vendor/seller with a good returns policy just in case a new module doesn't resolve the issue.  Jack E/NJ

    Thanks, That was gong to be my next step, although reluctant to buy a new one. I'm wondering if it is possible to test a RAM module "offline" ? Perhaps a PC repair shop might be able to confirm if the module is defective or not, without having to put it in a PC ?

    A brand new 8GB DDR3L laptop module is fairly common and costs about $30. It'll fit just about any working laptop that uses DDR3L modules. ACER, Lenovo, HP, ASUS, etc. So it'd be easy for a shop to test. But they might want 15mins worth of labor to do it. Might be more practical just to get a new module.  Jack E/NJ
