My parents have an Inspiron 580 Desktop with 4GB (1GBx4) of DDR3L memory. I tried to upgrade the memory to with 8GB (4GBx2) of Crucial DDR3 memory but after putting in the new memory, the computer stays stuck on the Dell bootup logo. I've tried all configurations recommended in the manual but nothing worked. When I tried just one stick (4GB), the computer would cycle through booting and shutting down without ever getting to Windows. I tested the memory on another desktop to make sure it works, and it does. It should be compatible so I'm not sure what the issue could be. Any suggestions?
