On start up my Mac Book Pro shows a white screen with a spinning wheel. I have tried starting up with the Snow Leopard disk - all I get is a blue screen. I guess that this is a major repair job??????

If you have the exact same problem - take the computer to an Apple store or an AASP. Whichever is more convenient for you. If you have AppleCare call them!

I would go straight to 5. Reset the SMC. If all else fails, bring it in, the PRAM battery may need to be replaced.

I have a mid-2011 iMac running Mavericks. When I click restart the computer goes to a white screen with a spinning circle and does not go any further until I hold down the power button to turn it off. What do I do?

Ok, sounds like the safe mode boot worked... You probably don't want to always be in safe mode though (some reduced functionality) so does it do a normal boot now? If not, you should then reboot into safe mode and run Disk Utility. Then select Macintosh HD on the left hand side, and click the Verify Disk button. If needed, it will ask you to Repair Disk. If there are errors found, Repair Disk again until there are none. Then try another normal boot and reply with result, wether good or bad.

Sounds like you may have a harddrive issue. You are probably going to need to get that changed out and then install the OS X again to get it going.

My macbook pro will not boot. It gets the grey screen with the apple until the bar is half way across and then shuts down. The only screen I can get to is in safe mode and I don't know what to do with that
