safari frequently freezes

Question

Series of "spinning wheel of death" freezes over a period of several weeks/months. 2011 IMAC, tried upgrading to yosemite, upgrade failed. Took the apple store, told hard drive was corrupt and RAM (4GB) was getting close to the limit. Paid to replace the hard drive, upgraded RAM to 16GB, thought everything was fine, problem persists.I have since run disk utility from safe mode to verify/repair disk, problem persists. This is obviously extremely frustrating, as the MAC is freezing literally every time we attempt to browse the internet. Any help/advice would be greatly appreciated.

update, now freezing during various processes, just tried opening a folder on the desktop and got the wheel. Really frustrating experience.
