Random BSOD

[limcz87]

I jz bought a new full system,
have been getting random BSOD,
most of the time only during a long period of computer rest,like after the destop is turned off overnight and I use it early at the morning(most of the time like this),

I tried memtest,HDD tool,linx and prime 95 stress test,all come back with no error,
check disc,sfc/scannow tried,no problem.

I attached the minidump,
can anyone help me please.

i am using windows 7,
my full system spec is :

asrock h55-le,
inter core i3,
radeon HD5770,
seagate 500GB,
PSU 400w.

i jz recall that,
everytime before blue screen appear,
i will encounter the problem like "explorer has stopped","explorer is not responding"

i suspect CPU north brige voltage not enough,

i am using asrock H55-le motherboard,
it doesnt have NB voltage option in BIOS,
there is only:
CPU voltage,
DRAM voltage
PCH voltage
VTT voltage
1.8v PLL
GFX voltage,

any idea?
