BSOD ntoskrnl.exe+71f00 :(

my computer stucks after getting a BSOD:
The problem seems to be caused by the following file: nvlddmkm.sys

SYSTEM_SERVICE_EXCEPTION
*** STOP: 0x0000003b (0x00000000c0000005, 0xfffff960001644f3, 0xfffff880088e9020,
0x0000000000000000)

*** nvlddmkm.sys - Address 0xfffff88010024742 base at 0xfffff8800fe2f000 DateStamp
0x537a8efc

usually it happens when I switch from a game to my desktop (alt+tab).
as I noticed it is from the nvidia driver or software.....did like I read from other threads..re-installed the drivers by unchecking some of the features....but nothing helped (

what else should I do? HELP PLEASE!!

dumps attached

Im seeing lots of this in the event log;

Event[0]:
Log Name: System
Source: Disk
Date: 2014-04-16T08:58:23.627
Event ID: 51
Task: N/A
Level: Warning
Opcode: N/A
Keyword: Classic
User: N/A
User Name: N/A
Computer: Admin-PC
Description:
An error was detected on device \Device\Harddisk3\DR4 during a paging operation.

Heres what microsoft have said;

If a generic error occurs when your computer pages information to or from the disk, an Event ID 51 event message is logged. In a paging operation, the operating system either swaps a page of memory from memory to disk or retrieves a page of memory from disk to memory. It is part of the memory management of Microsoft Windows.

However, the computer may log this event message when it loads images from a storage device, reads and writes to locally mapped files or to any file (as long as it is buffered I/O). The computer does not log this event message when it performs nonbuffered I/O. You can troubleshoot an Event ID 51 event message exactly like you troubleshoot Event ID 9 or Event ID 11 event messages.

Yeah il just look at the dumps.

possibly a outdated driver, please check the link for more information on updating drivers.

Update a driver for hardware that isn't working properly - Windows Help

I can't read the dumps at work, but the very first thing you should do is update to Service Pack 1 via Windows Updates.
