Nothing clearly defined by these crashes, but I see some problems.
First, I don't understand the need to have both the Intel onboard graphics drivers and the Nvidia graphics drivers both installed and enabled together. I can see them working together, but I can also see them not. It's unnecessary anyways. Make sure to uninstall the one you do not need.
Second, I see you have both Norton Firewall and Zone Alarm. Having these both on at the same time is a definite no-no, and
will cause issues, most likely the ones you're experiencing now (I did see them in the raw stack for each faulting thread). While I do not recommend Norton products (they are unstable and use very invasive tactics), I definitely would not recommend Zone Alarm either, since it has a reputation for being buggy and unstable. If you were given the option to remove only one of them, I would go with Zone Alarm, as well as updating Norton Firewall. I also see McAfee drivers present. Exactly what AV/Firewall software do you have installed? You should have one dedicated AV software and one firewall software (preferably just one software with both). If there's any overlap, there
will be problems.
Lastly, I notice a lot of your drivers got a bit of age to them, like your Realtek LAN drivers. Make sure to keep em all up to date. I understand Dell has a bad reputation for having their drivers stagnate, but make sure there's any updates just in case.
Otherwise, aside from all that, I can't see anything entirely definitive here. If you wish, you can turn on
Driver Verifier and let your system crash a few more times. Do
not select the following checks:
IRP Logging, Force Pending I/O Requests, and
Low Resource Sim. Follow the rest of the instructions in the article linked and make sure to read them all entirely.
