1) Laptop shuts down when hibernating 2) Windows Explorer stop responding when inserting USB, resuming from sleep/hibernate

Hi guys, this is my first time posting, sorry for any mistakes made.
Please advise me to give any information that you need.
I have 2 problems with my Acer laptop 3820TG-624G64n. 
The below is the specifications for my laptop:
i7 620M (2.66GHz), 4GB ram, 640GB HDD, ATI Mobility Radeon HD5650, Windows 7 Home Premium

1) Whenever I close my lid, my laptop is suppose to hibernate.
However when hibernating for around 20-30mins, it will shut down abruptly.
When I resume by pressing the power button, the system powers on like it has been shut down and shows the options
"Start windows normally".

The following is the error message from the error warning window.
Problem signature:
  Problem Event Name: BlueScreen
  OS Version: 6.1.7601.2.1.0.768.3
  Locale ID: 18441

Additional information about the problem:
  BCCode: 9f
  BCP1: 0000000000000003
  BCP2: FFFFFA8004F4BA10
  BCP3: FFFFF80004DE0518
  BCP4: FFFFFA8004814A20
  OS Version: 6_1_7601
  Service Pack: 1_0
  Product: 768_1

Files that help describe the problem:
  C:\Windows\Minidump\051311-22916-01.dmp
  C:\Users\Darrel\AppData\Local\Temp\WER-77828-0.sysdata.xml

2) Around 60% of the time when I 
a) plug in a USB
b) when I resume from sleep/hibernate
c) when I plug out USB
the explorer.exe on my laptop will stop responding and the whole laptop gets really slow until I manage to click on "Restart Windows Explorer".
And this problem is intermittent and does not happen all the time.
I followed a guide on how to make a .dmp save
file when encountered an error.

I have been updating my drivers to the latest version according to Acer Singapore website, but nothing has been solved.
Problem 1) is a newer problem that did not exist in the past, only recently.
My assumption is, it is due to either Windows Update or
driver update, but more on Windows Update.
I remember seeing the Windows Update for systems that have a TB hdd and resuming from sleep/hibernating would cause problem.
I had that patch/fix installed if I am not mistaken.
Please advise what are the next steps I can take to further troubleshoot the problems or the direct solutions.
Thanks in advance.

D.
