Inspiron 5480 does not start after RAM upgrade

I try to upgrade the RAM from 16 to 32 GB, with a Kingston 16 GB - 2666 mhz, it went well until the laptop turn off with the screen started to flash and go out, then it didn't start anymore until I left only the original RAM memory, the warning LED that it doesn't recognize PCI/VIDEO with 2 amber flashes and 3 white flashes. Any tips?
