I recently received an all in one pc. They gave it to me because the bios only loads about 1 out of every 12 times I turn it on. This started happening after they updated it to Windows 10. When it doesn't boot, the fans spin and the screen turns on but nothing is displayed. I've reseated my ram and cpu and still no dice. I've reset the CMOS by taking the battery out, and it's still the same. Could the update corrupt the BIOS? Thanks for your help :)

How could I update the BIOS if the computer won't even boot? All the fans and lights turn on, but there is nothing else happening. Are you saying to update it when it does boot every once in a while?
