Solved Laptop hang with buzz sound, persist after reformatting

[Tyrhung]

Hi all

Not sure if mine is considered BSOD (there isn't any blue screen, it just hang/freeze with buzz), my laptop just hang there and frequently comes with a buzz sound. It depends on the program being in use. With media playing (Browser stream or MPC), there will be a buzzing sound when it hang. If it was on a normal window explorer, there isn't any.

It happened a month ago, from occasionally to now frequently several times each day. So i reformatted my laptop 3 days back, however the problem persist. Now the freezing can happen anytime, even at the windows log in screen before seeing the desktop.

I've uploaded the DM log collector as well as told by BSOD - Posting Instructions and the msinfo32 if required.

Here are my Laptop Specs using dxdiag in "run"

OS:Windows 7 Home Premium 64-bit
BIOS: AMIBIOS Version 05MX.M008.20110525.SCY
Processor: Interl(R) Core(TM) i5 CPU M 460 @ 2.53GHz
Memory: 6144MB RAM

Display
Intel(R) HD Graphics
Approx total Memory: 1696MB
Chip Type: Intel(R) HD Graphics (Core i5)

Sound
Realtek HIgh Definition Audio

Any help will be greatly appreciate!
