 Unfortunately, the Blue Screen of Death is alive and well. We all were hoping that Microsoft, with Windows 7, would have tightened up the driver issue, but the fact of the matter is bad drivers are still prevalent in the marketplace. And there is no telling what end users are installing on the PCs these days. So your best bet is to know where to find the memory dump file that is generated after your PC blue screens to accurately know what caused the issue.

First off you are going to need the Debugging Tools for Windows. They can be downloaded <strong><a href="http://download.cnet.com/Debugging-Tools-for-Windows/3000-2086_4-10907878.html">HERE</a></strong>.

Once downloaded, perform a complete install
Once installed open the program, by going to START &gt; All Programs &gt; Debugging Tools for Windows &gt; WinDbg
Once the program opens press CTRL+D (to open a memory dump file) and navigate to your memory dump  file (usually you can go to C:WindowsMinidump)
Next the debugging  tool goes to work and give you its best indicator of the blue screen culprit

This identification of the Blue Screen culprit will go a long way to getting the root cause actually resolved.
