Dell Inspiron 15 stuck in factory reset loop

I have a Dell Inspiration 15 with win 10. it was bogged and slow as syrup on 125 degree day. I did a factory reset. I followed the instructions went to settings, and just followed the steps. At some point during the reset it asked me about tpm2 settings...I had never seen that before so I followed the recommended choice and went to bed. When I got up it asked me for the usual stuff, location, language, time zone. Then it wanted the name of my WIFI and my password, which I gave. It restarted, then just kept on restarting asking me the first set of questions, language, time zone...over and over, it never asked for internet name or password again, . I can get in to the bios settings by using the f8 key.
Any suggestions? Hopefully...
OH I almost forgot, when you do a hard restart, it flashes a tpm2 settings error right before it starts with the dell screen and spinning dots

Wifi Very Slow

Hi,

The following are some reasons that may cause of the slow WiFi connection.

• Corrupted or incompatible drivers.
• Missing updates.
• Network connection settings.
• Hardware or software problems.
• Inappropriate distance from the router or obstruction.
• Interference with other devices.

To isolate the concern, have you checked if the issue persists with other devices? For now, we suggest that you follow the troubleshooting steps provided in this
