Hi Yvette,
Your minidump files indicate the following two drivers are contributing to the crashes.
cfosspeed6.sys - this is a virtual driver associated to a utility named CFOSpeed, which is meant to speed up your network connection, you should uninstall that, it is know to cause blue screens.
e1d68x64.sys - this is the device driver on the Intel Ethernet (Wired) Network, go to the support page for your PC on the manufacturers website, then from there, download and install the version of that device driver they recommend
