Update = After completing troubleshooting, a DELL-Cares agent setup a part replacement.
I had a heck of a time doing a bios update awhile back, but it finally updated. I used support assist to update a video driver, and then everything went south. The computer rebooted a few times, then did the RGB colors on the screen, and now it's turned on but the screen is black and flashing 3 amber lights, 5 white lights, repeat. I can't turn it off, holding the power button does nothing, the fan is just running and I guess I have to wait for it to run out of battery. Everything I'm seeing says the motherboard will need to be replace, which will make this the 3rd motherboard replacement for this machine. Is there anything else I can try?
