random BSOD and sometimes freeze on shut down

before i try to restore it
suddenly the network connection doesnt work, but in the connection manager, it was written that there is an internet access.
ang it hangs up several times

still 'attempting repairs'

the start up repai Done with a failure
but the windows can be started on THE LAST POSITION (it means the recovery failed)
but the boot time is faster than before start up repair occured

let me check it again
will inform you again

replace delldock with the 32 bit version and work smoothly

i count the time of my windows load up
from windows loading screen to logon screen about 15 seconds
from login screen after enter the password to my edsktop, needs about 45 seconds
i think its too slow
any idea how to make it faster?
my start up only mcafee, mse, synaptic toucpad, and blue tooth tray
before the failed restoration, it takes faster than this

hanged up again when i updateing somedrivers (vga, lan, sound)
when the driver ask to restart, i restart, then it hang in the 'force restarrt screen'
then i hold the power button, powered it up again, it bsod and restart

im dumping the data now
ill attach them soon
