I have a Dell Inspiron One 2330 AIO Desktop that when boots up displays a black screen. This happened after I changed the boot options to boot from a thumb drive to boot to the hard drive. The computer was looping over and over asking to choose a way to boot the computer. That is why I changed the boot option to my thimb drive and i tried to reinstall windows but it didnt work. So i changed the boot option back to the hard drive and let the computer boot up again from the hard drive. Then it boot up into a black screen. I turned it off , unplugged it and every time i turn the computer on it will boot into a black screen, no dell logo showing. I tried pressing f12 ,f8 , but it will not take me back to the bios screen at all. Geek squad contected the computer to another screen and tried pressing ctrl, alt , del to reboot the computer but that didn't work as well. Geek squad says i have to replace the motherboard because it could be fried. But the computer was working find before changed the boot option. The computer isn't mine . Its a friends and I was trying to help them out. So someone please help me resolve this issue!!!!
