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
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
