Let us know how it goes

Please uninstall kaspersky, it's known to cause BSoDs on some systems
Use Microsoft Security Essentials (at least to test)
Make a full scan once installed and updated
Run this tool and delete anything it finds:

• Anti-rootkit utility TDSSKiller
• Microsoft Security Essentials - Free Antivirus for Windows

Run the System File Checker that scans the integrity of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

• SFC /SCANNOW Command - System File Checker

Look for an update on the BIOS version:

Code:

BIOS Version/Date    American Megatrends Inc. V3.4, 20/10/2008

I've mentioned "(at least to test)" on my post.
Anyway, no it does not matter.

Do the update when possible.
