2010 Unibody Macbook won't start up.
My son has a 2010 unibody white macbook that began having some startup issues with recognizing the hd. We replaced the hd and have the following issues. I can't get it to load an operating system without it powering down. Whether I use an optical drive or a start-up disk on a flash drive, after a few minutes the machine just powers off. Since it just powers off, I cannot get Disk Utility to come up so I can look at anything. Could this be ram issues...or a logic board...or what? How can I test a machine that won't stay on?
I cannot give specifics on the machine because I cannot power it up and my son has no idea (duh).
