about !drivers

My driver is a disk filter driver.Recently I find that My computer always
stops when first booting every day.
And it will success to boot when I reboot my computer after blue screen.
The blue screen code is
0x00000067,(0x00000004,0x00000007,0,0)
CONFIG_INITIALIZATION_FAILED
or
STOP: 0x00000074(0x00000005,0x00000007,0x00000000,0x00000000)
BAD_SYSTEM_CONFIG_INFO
At first,I think that it is caused by my filter driver.So I do remote
debugging with windbg.
When I capture the error,I use !drivers to see all drivers loaded on the
target computer.I find my driver in the list.
But my driver is not loaded in fact,because I set a break point at
driverentry routine,the break point do not be actived.
So my first question is: why the command !drivers show my driver?

I already know the cause to the blue screen.
“This issue may occur if one or more of the random access memory (RAM)
modules that are installed in your computer is damaged or if the RAM
configuration is incompatible.”

My second question is:If or not the system is allocating the memory for my
driver before bluse screen?

Thanks all.
