I have a 15 inch macbook pro that's about three years old (just out of warranty) and I'm experiencing some weird issues.

1. When I can boot into the hard drive it works for about ten minutes and then I get a frozen (spinning) beachball cursor and can't do anything but move the cursor.
-If I run disk utility the hard drive completely disappears off the list after about 10 minutes. It's a brand new, correctly formatted HD so I know that's not the issue.

2. When I go to startup I get the blinking question mark folder. If I shut it off and leave it alone for a little while I can try again and it will usually find the HD and then I have the previously mentioned problem.

3. Sometimes (it's inconsistent) when I go to boot from a cd the cd will simply be ejected and I'm left with problems 1 or 2. The track pad is not pushed in.

I have reset the PRAMs more times than I care to count, have uninstalled and reinstalled (albeit from a time machine backup) and have attempted to try a ubuntu live CD I made, but the CD is constantly ejected back at me. (It's quite aggravating).

I think it's a bad logic board, but I'm praying I'm wrong. Any ideas?

I would be more apt to believe you have a bad HDD and an intermittently flaky Superdrive.

The hard drive should be easy (and cheap) enough to swap out. I would start there.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

Agreed. The blinking question mark and Disk Utility results strongly suggest a failing hard disk or bad/loose HD cable.

That's what I thought, so I literally replaced the HD yesterday with a brand new WD 500gb SATA drive. Still having the same problems.
