My PB 867mhz is approx 2.5 yrs old.
It has always performed well...until a week ago.
Everything got very slow and I started getting error messages about settings "being off" when they actually were on, so I decided to format and reinstall everything.

It was all fine 'til today, when the error messages comes back and out of 20 files i print to disk from Logic Pro -only 10 shows up on disk.

I need my PB to be in 100% shape so my question is:
DOES THIS SOUND LIKE A HARDWARE ISSUE?
If so, I'm concidering getting a new mac, but I don't wanna do that until I can see if this is fixable for far less money...

Any replies and tips will be greatly appreciated. Thanks!
