What about going into Disk Utility and reformating the drive? Then reinstall. Maybe something is wrong with the Time Machine backup.

Presumably you mean you made a Time Machine backup before you had the hard drive replaced and then restored from Time Machine to the new drive?
A few things you could try using the Recovery Disk. Restart holding down Command+R to boot into the Recovery HD. Once booted select Disk Utility, select Macintosh HD and click on Repair Disk. If it makes any changes repeat Repair Disk until you get a clean pas. Whilst you are in Recovery HD, after repairing the disk click on Repair Disk Permissions. Restart as normal from the Apple menu. Is it any better?
You could also try a 'Safe Boot' which can sometimes help. Restart holding down the Shift key until you see the grey progress bar. Once booted restart as normal from the Apple menu. Test machine.
If that doesn't help you could try re-installing the OS (option is there in Recovery HD). You could also try doing the Time Machine restore again. If all that fails, I guess it's back to Apple.

EHave you checked for software updates? When the new hard drive was put in the OS may not have been up to date.
