    Hello Everyone

    After I upgraded my 4 GB stock ram to 8GB ram, there is a 1second blue screen at the end of lion start-up.

    MBP early 2011 2.0 Quad

    system information shows that rams are fine. I also ran memtest and passed the tests

    I also filmed the start-up

    these are the new ram i installed on MBP CMSO4GX3M1A1333C9

    Thanks for reading my post

    I believe that is normal. I have it on my Air since I purchased it. Same thing with my MBP.

    Same here. Mine is for ~3 secs at startup, before going to desktop

    Actually, the blue screen is NOT normal. I had the same issue with my MacBook Pro (not really an issue but...). All I had to do was reset my PRAM and it solved the issue. If resetting your PRAM doesn't work, I don't really know what to suggest because that's what solved it for me.

    Here's the instructions on resetting your PRAM from Apple:

    I don't know when my Macbook start showing blue screen as well ... when I bought this Macbook early January, everything is fine ... I have tried reset PRAM and some other clean caches....nothing help ... it is a little bit annoying for MacOSX Lion to show something like this...if this is a Windows Laptop, I can understand.
