Hey Folks, I"m wondering if using the disk utility wipe and re install is the best idea in order to do a re image of my MBP? I"m having a ton of problems w/ crashing and hanging etc...

MBB, mid 2010

Take it MBB is really MacBook Pro?

Suggest increasing memory to 8GB, download Yosemite again and burn to an 8GB USB thumb drive using DiskMakerX if you do not have an existing copy. Then back up to an external. Boot from the thumb drive, go to Utilities > Disk utility and erase and format the drive Mac OS Extended (Journaled). Back to the Installer and proceed, use Migration Assistant to bring things over from the backup, then update to version 10.10.2.

You cannot erase a drive you are booted from. Machines that have gone through upgrade after upgrade can, imho, benefit from a clean install.
