Hello AntiNEO, welcome to SF!
Seems you get most of your crashes playing Call of Duty correct?
A couple of things to check:
1. Finish Windows Update. Something is wrong there and could have messed up drivers
Please go to your Maintenance Center and check the Windows Update status. Make sure you are up to date, do them one by one manually if needed.
For help or reset see: Windows Update - Reset
2. Your system also has a problem with some plug and play device that it has not yet found correct drivers for. In what order have you been connecting devices?
3. Please also de-install Daemon tools until proven stable. These are known to cause problems in Windows 7.
To make sure you get dumps in the future:
To ensure minidumps are enabled: Dump Files - Configure Windows to Create on BSOD
Go to Start, in the Search Box type: sysdm.cpl, press Enter.
Under the Advanced tab, click on the Startup and Recovery Settings... button.
Ensure that Automatically restart is unchecked.
Under the Write Debugging Information header
Select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
OK your way out.
Reboot if changes have been made.
