You have a ton of crap (literally, junk applications) loading at startup. I'm betting that's the cause of your BSODs.

Facebook Update REG_SZ "C:\Users\Sharon\AppData\Local\Facebook\Update\FacebookUpdate.exe" /c /nocrashserver I want you to disable all of the red highlighted entries. Hit the windows key and type msconfig. Go to the Startup tab and you should see all of those entries I listed above. Remove the checkmarks for the above entries (except for the mcafee entry - see my notes below). After you do that, hit ok, then reboot the machine.
You'll notice I added extra emphasis to the mcafee entry. I want you to completely uninstall McAfee. I'm guessing it's just a trial anyway if this was preloaded on your Dell. Once it is removed, download and install Microsoft Security Essentials.
Once all of that is done, you should uninstall as much of the Dell crapware as you can - the preloaded applications that are trials/bloatware/etc.
Do all of that and come back and let us know if that helps.
