There are a few issues here. All may be related to your Zone alarm. I would remove and replace it with MSE.

I notice your PCTools which is often the cause of BSOD's. I would remove and replace with Microsoft Security Essentials AT LEAST TO TEST

1-NETw5v32.sys (your network driver) is from April 2010 and should be updated.

2-usbehci.sys. Your USB driver. It is from 2009 and should be updated.

3-SP-1. Some/all of these may be fixed by updating to sp-1

Please run the System Update Readiness Tool (SURT) and then update to SP-1
