Conclusion
--------------------------------------------------------------------------------
3 crash dumps have been found and analyzed. Note that it's not always possible to state with certainty whether a reported driver is really responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.
any suggestions? thanks!
