- the presence of sptd.sys implies that DaemonTools is present. And DaemonTools has been causing BSOD's since the early Vista days. So kindly remove Daemon Tools.
- Truecrypt needs removing - the app is vulnerable, and this may contribute to attacks on the system from the outside. As these BSOD's seem to have networking issues at the core, this is a concern.
- the outdated tap0901.sys driver has been showing up more and more in different memory dumps across EightForums. As such I suspect that this driver has recently become incompatible w/8.1 and I always suggest that they update it to the latest, Windows 8.1 compatible version.
- finally, the Kaspersky can be causing problems due to corruptions (this is based on my past experiences with Internet Security apps, not because of anything that I saw in the dumps). The easiest way to solve this is to uninstall Kaspersky and then reinstall a fresh copy from the Kaspersky website. Why? It'll take us longer to troubleshoot and rule out Kaspersky than it will to uninstall/reinstall/update it. I'd do this last (after updating/removing everything else).
