Question: Troubleshoot Macbook Pro Shutdown?

I've recently been trying to troubleshoot this problem I've been having with my macbook, I would start my macbook and immediately see a progress bar, and soon after the laptop will turn off. I also tried running diagnostics but it would freeze, also tried installing a new HDD but will shutdown during the creation of a new HDD, and also tried replacing the RAM. But no luck, I try to keep fix the problem but stuck can someone help.

RE: SATA Cables:

Brue computing posted an interesting Video on Youtube. The proposition was that the SATA cable problems in certain MacBooks was caused by abrasion against the machined inside of the aluminum case. Their solution? RED TAPE!

(The drive has been removed for photographic clarity)

One strip applied to the case, and one strip applied to the underside of the cable.

You should use RED tape because it is associated with higher speeds, and will therefore keep the high speed bits from spilling out of the cable and accumulating inside the case.

OGELTHORPE insists that I have a fiduciary responsibility to tell you that--^

Many Users prefer to simply replace the cable than get involved with all this "red tape".

I kept running to verify disk on the original and a replacement HDD, but neither couldn't verify or repair disk, and i hope replacing the ribbon cable will work. But also i noticed that when i try to run diagnostics it freezes, and when i leave the laptop alone without interaction for a few seconds it shutdowns complete. my question is that could this SATA ribbon cable could this problem as well?

While it is possible you have a more complex problem, you must be very patient while the diagnostic works.

Once the diagnostic loads into RAM it does not use the disk again (except during brief disk test). However, it does spend about ten minutes or more beating on the RAM so furiously that it does not have any extra cycles to update the screen. It may seem to freeze, but is in fact still working as designed.
