  Hello Chucko,
  
  I'll give you instructions for updating the BIOS to the latest P11.B4.  
  
  I think you should check your existing memory and see if it is DDR3L 1.35 V or DDR3 1.5 V.  It will be written on the label on your memory.
  
  If your existing memory is 1.5 V, I would recommend the Kingston memory below.  Try to match the same 1.35 or 1.5...whichever you have.

  In theory, it shouldn't matter mixing DDR3 and DDR3L on your xc-605 desktop mainboard, but I remember someone else had a problem mixing for some unknown reason when using DDR3L Crucial memory on their XC-605.  If you're in doubt, I would recommend the Kingston memory.
  
  Here's instructions for updating your BIOS, but I don't think that's really your problem. 
  
  

  The standard operating procedure (SOP):

   

  1. Download P11.B4

  2. Extract

  3. Copy the Win and ROM folders to a USB flash drive.

  4. Open an admin command prompt

  5. If your USB flash drive has a drive letter of F, then you would type

   F:

  cd win

  flash

   

  6. After the processing completes, restart your computer

  7. When it prompts you to enter the BIOS, press the "delete" key on your keyboard to enter the BIOS settings

  8. Load the BIOS defaults (F9) and then save/exit (F10).

  @Chucko
  
  Your mainboard should work at either 1.35V or 1.5V.    But for whatever reason, it doesn't like mixed ram.  If you install two 1.35V DDR3L modules, it will work fine.   If you install two DDR3 1.5V modules it will work fine.    DDR3L is supposed to run at 1.35 or 1.5, but for whatever reason, your mainboard/UEFI doesn't like mixing DDR3 and DDR3L.
  
  My mainboard is running 1.5V DDR3.  (I have TC-605 which uses the same mainboard as XC-605)

  It could be just a matter of pulling out the CMOS battery for a couple hours and resetting BIOS.  But I don't want to waste your time with guesses.  If your computer came with 1.35V, it's probably best to just return the 1.5V and get some 1.35.

  If I remember correctly, if you install a single stick of ram, you must put in the slot closest to the CPU

  If you unplug the computer from the elctrical outlet, and pull out the CMOS battery for a couple hours, it will reset the BIOS.   I wasn't talking about updating the BIOS.

  If you're not comfortable.........It might be best to just try to sell your 1.5V memory on ebay.  And then get the 1.35V in link below.

  To Flash it. Simply unplug your machine and take out the battery. Hold power for 30 seconds, plug machine in, hold fn+esc, press power,  let go of fn +esc after machine starts.
  
  To create USB.  Open cmd as admin. 
  Diskpart 
  List disk
  Select disk "your disk number no quote "
  Clean
  Create partition primary 
  List partition 
  Select partition "your partition number"
  active 
  Format fs=fat size=4000 quick 
  
  Download the Acer bios from drivers and downloads, extract the exe,  and place the contents on the USB
  
  NOTE: If you try to do the wrong version; and keep holding FN+ESC, you will enter efi shell where you can load EFI protocols and device drivers, and execute simple scripts.
