Here What exactly Error is...
A problem has been detected and windows has been shut down to prevent damage to your computer.
Driver_IRQL_NOT_LESS_OR EQUAL
If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your Hardware or software manufacturer for any window updates for you might used.
If problem continues, Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup options, and then select Safe Mode.

Technical information:

*** STOP: 0x0000001 (0x000000c, 0x00000002, 0x00000000, 0xB9915AFC)

Potentially your PC is having a problem with Kaspersky Antivirus and may need to be uninstalled or assisted by other malware cleanup tools run in SAFE MODE (such as CCleaner):

As an aside, you may want to consider (both FREE);

Avast Free Antivirus - Free software downloads and software reviews - CNET Download.com

COMODO
