Is the AMD Radeon RX570 Dell's OEM video card or did you replace the OEM card along the way? We can certainly get another one when time allows if you think it will help. Followed your instructions, although we did not replace the battery (none on hand, and unable to get one today). Followed power on, power off cycle.Ĭorrect.

Monitor = one VGA, one HDMI.Ĭonfirmed 'HDMI', 'Auto'. Video card = one HDMI and three Display Ports.

Tried this sequence multiple times, but same end result. Look for option to boot from USB on the menu and follow the prompts to repair Win10. With the Inspiron 5675 powered OFF, plug the bootable USB with Win 10 into the PC, power on and immediately start tapping F12. If you can see the F12 menu, go to the MS site and follow the instructions to download and create a bootable USB stick (use at least a 16 GB stick, even though they may say 8 GB). If you can see BIOS setup, check if Secure Boot is enabled or disabled. If you reboot and immediately start tapping F2 (or F12), can you see BIOS setup open (or the F12 boot menu open)? If you can't see BIOS setup or the F12 menu, it's going to be hard to boot from a USB stick because you'll need to see the F12 menu to choose booting from USB. With PC off, power monitor off and then on again first, before powering the PC on. If none of those, choose the next lower resolution than the one that's set now. What ports are on your video card and on the monitor?ĭoes the monitor have its own On-Screen Display (OSD) that's opened by pressing a button(s) directly on the monitor? Open the OSD and look for option to select the input port and make sure it's set to HDMI, then look for resolution options and if there's an 'automatic', 'native', 'recommended' or 'optimum' choice select that.

Close up and connect mouse, monitor and keyboard.

Reinstall battery (Time for fresh CR2032 3-volt coin cell battery? ~$2.00).

Open case and remove motherboard battery (check Service Manual for details).

If that doesn't help, before going too much further, try clearing BIOS:

What different wait times did you try? Try waiting just until the keyboard NumLock and CapLock LEDs blink and then start/repeat the power off/on cycle when the LEDs blink.
