Ignoring the discussions about level of expertise and the correct procedure for what you should have / could have done:
System boots in safe mode, won't in normal.
Odds are drivers - already established.
Have you analysed your crash dumps?
Bluescreenview is worth a look for this, see which drivers are in memory when it crashes. Is it the same drivers each time etc, what are they linked to. Those questions should get you pointed in the right direction.
Also I'm assuming you cloned directly to the new drive. If not and you have a backup image then just go back to that and start again. Or reclone the old hard drive if it's still standing (to a THIRD hard drive in case goes completely wrong) and then see if it loads up in the customer's pc after fixing corruption. If it does, linked to your updates, if doesn't then wasn't linked.
Time consuming yes but if it saves you reinstalling certain annoying and time consuming programs, worth a go.
The system loads in safe mode. You should be able to get it loading in normal mode on the vast majority of repairs, in my experience.
