Hi Turdbo,
Thanks for posting. It appears you may have more than one issue here. Were you having a problem with your computer prior to updating the drivers? Normally a driver update is not needed unless you are experiencing an issue. Just curios as to why the update?
As for the reinstall, it is possible you might have a corrupted installation media. Are you installing from a disk? USB? or some other device?
Here is an article from the Dell Knowledgebase that addresses the error message you received.
It is required that the agents troubleshoot issues over the phone prior to discussing any type of repairs. You said you ran a diagnostic. Here is the link to the Dell Diagnostics.
Post back so the experts here can assist further. Thanks.
