got the windows 10 free upgrade and used the dell diagnostics tool to upgrade driver and bios everything worked fine until the update of the bios!!!!
once the update started it rained go maybe 15 seconds and just shut my computer off entertainment a bloatware screen say that the software ran in to an error and it would restart itself. I let the computer along for over an hour and finally restarted the system muse us in the power button. once I went to restart the system I only got a blackberry screen my computer is out of warranty and your dell bios update killed my motherboard I called dell they told me in not so many words my motherboard was Fried and they would not replace it. If I gave some on software I wrote and they installed it and it had no warning it would fry the I computer thatbwould be data to someone's personal property... DELL is this how you value your customers?
