BSOD and frequent crashes when playing League of legends game

Whenever i play this game i get frequent BSOD/Crashes with the prompt that the application has stopped working. I had problems with BSOD before but resolved them by changing the RAM sticks to the correct positions.
I only recently started playing this game and i only get the crashes when playing it.

On Tue 09/04/2013 08:49:04 GMT your computer crashed
crash dump file: C:\Windows\Minidump\040913-16988-01.dmp
This was probably caused by the following module: dxgkrnl.sys (0xFFFFF88005211022)
Bugcheck code: 0x50 (0xFFFFF8800894C280, 0x0, 0xFFFFF88005211022, 0x0)
Error: PAGE_FAULT_IN_NONPAGED_AREA
file path: C:\Windows\system32\drivers\dxgkrnl.sys
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: DirectX Graphics Kernel
Bug check description: This indicates that invalid system memory has been referenced.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.

Thanks!

Could not read faulting driver name
Probably caused by : dxgkrnl.sys ( dxgkrnl!COREACCESS::AcquireShared+a2 )

Code:

Usual causes:  Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus,  Device driver, NTFS corruption, BIOS

A invalid memory address was referenced, and this case was the non-paged pool region, which is reserved for Kernel Mode processes.

Update:

Code:

1. Download Driver
2. Start Type: Device Manager
3. Expand Display Adapters
4. Right-Click Driver Name, Uninstall
5. Reboot
6. Run Driver Sweeper
7. Reboot
8. Install Downloaded Driver

Driver Sweeper will scan for any left over files from the old driver, old driver files can cause conflicts with new driver installations. Create a System Restore point beforehand, in case any problems or issues arise.

Driver Sweeper:

• Drivers - Clean Left over Files after Uninstalling

Remove:

Code:

Start Menu\Programs\PC TuneUp Tools

Windows 7 doesn't require any programs which make changes to the operating system and registry, these programs tend to cause problems by modifying and deleting files.

• Registry Cleaner Tests - Why NOT To Use One!

Remove:

Code:

Start Menu\Programs\Alcohol 120%

Alcohol 120% uses a driver called sptd.sys, which is known to cause BSODs with Windows 7.

Reduce the number of programs at startup, to avoid any driver or program conflicts:

• Troubleshoot Application Conflicts by Performing a Clean Startup
• Startup Programs - Change

I updated my nvidia drivers like you said and removed pctuneuptools and alcohol. So far i havent had a bsod since but now the game keeps on frequently crashing and windows prompts me to close the program.
I have attached the dump analysis.

Thanks for your help!

Probably caused by : ntkrnlmp.exe ( nt!ExQueryDepthSList+3 )

Code:

Usual causes:  Disk corruption, insufficient physical memory, Device driver, Indexing, Resident antivirus, backup, defrag programs, Disk/Drive failing/failure

I found this BSOD, which occurred at 12:52, I'm sure this wasn't in the folder when I first checked
