My Crucial M4 128gb was running perfect for just about one year. Now my computer crashes from time to time and the Crucial m4 nowhere to be found in the boot up sequence. In addition, a red light appears on my Asus MB. I have to shut down my computer(instead of a restart) and go into my bios to reset my ssd for bootup. Can anyone point me in the right direction if it might be my SSD or MB?
