I got a blue screen of Win7 while there was a running utorrent 3.1.2

Below is the result of windbg.exe.

My PC is aleady rebooted and I could not get the result of hijackthis.log and processexplore.log at that moment when I got a blue screen.

What is the cause of a blue screen and what should I do?

(I don't use any kind of antivirus program.)

PAGE_FAULT_IN_NONPAGED_AREA (50)

Invalid system memory was referenced. This cannot be protected by try-except,

it must be protected by a Probe. Typically the address is just plain bad or it

is pointing at freed memory.

Arguments:

Arg1: 90a0f000, memory referenced.

Arg2: 00000000, value 0 = read operation, 1 = write operation.

Arg3: 90a11581, If non-zero, the instruction address which referenced the bad memory

address.

Arg4: 00000000, (reserved)
