HELP! MBP keeps rebooting after "chimes" on startup!

[legaleye3000]

I have a mid 07 Macbook Pro and now when I turn it on, I will hear the Apple sound and then it just reboots and keeps doing that. Nothing on the screen comes on, its just black.

I am running Snow Leopard (fresh install) 10.6.1. Tried resetting PRAM and SMU and no effect...

PLEASE HELP! Thanks

have you tried holding Option + Command + P + R during startup? That restarts the PRAM and might sort out your problems.....

 

[legaleye3000]

Yes- as mentioned above... Resetting PRAM and SMU has not worked

Attempt to boot from install disc by holding option or D.

Its reboots so quickly I'm afraid if I put a cd/dvd in the drive, I won't be able to get it out...

I would take it to the Apple Store Genius Bar and have them take a look. Could be a dead hard drive, logic board or graphics card. Also, could just need a system reinstall.

Its out of warranty ... mid 07...

I have an extra hard drive... I wonder if I take out the hard drive and put my extra one in, if it will keep doing that... hmmm...

Sorry about that, I am having a stupid day!!!

The only other thing I can suggest is to use the OSX disk but as you said it may get stuck. If not how far do you live from your nearest store? I know that your not in warranty but they can still help you!

You can try that, but I feel it is a logic board failure. You might find a cheap one off of eBay...

Sounds similar to an issue I had this summer. Try running a hardware diagnostic (out in install DVD and hold D, if I remember right), then check the error code that you get. The issue with mine was a bad RAM chip. Once I pulled the RAM chip out, things worked fine. Mine was still under a year old, so the Apple store replaced it no charge.
