[NAME].Simpson  - Always include exact PC model in your posts. Since you mentioned BIOS 1.1.15, does that mean you have an XPS 8930, because there's a brand new BIOS v1.1.16? If my assumption is correct, BIOS 1.1.16 for the XPS 8930 fixes 13 Intel security issues.  You don't have to update, but then you might have a security risk because of these unpatched holes. If you decide to run the BIOS update, IMO, do not allow SupportAssist to manage the update for you. You should do it manually from inside Windows, according to the instructions on that page. Be sure you're logged into an account with Admin privileges, all apps and windows are closed and you have temporally disabled your anti-viral app before launching the update. Just leave the PC alone while it's updating. Don't press any keys or power off. It may reboot more than once, so wait until it's back at the desktop. Then make sure your anti-viral app is running again. There's another way to do a BIOS update on the XPS 8930 using a non-bootable USB stick, totally outside Windows, that's not mentioned on that page. I used this alternative method to update BIOS to 1.1.16 on my XPS 8930 last week and it went ok. If you do it this way, the PC might look like it stopped and fully powered itself off at one point during the process, but leave it alone until it's back at the desktop. EDITED
Do I need to update my BIOS? My computer currently uses "BIOS Version/Date Dell Inc. 1.1.15, 7/1/2020" I am updating my CPU to a "Intel Core i9-9900 Desktop Processor 8 Cores up to 5.0GHz LGA1151 300 Series 65W." Please advise. Thanks!
