I have Macbook Pro running Ubuntu 12.04 and it is freezing at Startup. I have to force shutdown when it freezes and then restart it, it will freeze again for 2-3 times or sometimes just 1 freeze and works.

Previously I had mountain lion in it and there it was also freezing intermittently after startup but Ubuntu fixed this issue.

I got this tested up by a local computer guy and he says, it needs logic board replacement. Logic board costs a lot of money and I think my best bet is to get its board fixed.

Can I troubleshoot which part of board I would need to fix?
 
Does it freeze at startup only when it's cold? Once booted, does it run properly?

Unless you have the diagrams and required troubleshooting equipement, it will be difficult to fix it yourself. Visually inspect it for bulged capacitors, make sure that all components are fully inserted and that nothing is shorting out to the case, etc. Other than that, you'll have to replace the motherboard if it really is defective.
 


I will check and let you know, I am away now. Thanks for your reply.
