When I try to turn on my computer, Windows attempts to boot, but is then interrupted by a blue screen with a stop error that says "STOP: 0x0000007B (0x81868a10, 0xC0000006, 0x00000000, 0x00000000) INACCESSIBLE_BOOT_DEVICE". Then it says to check for viruses, but I can't because it won't boot up. I've tried using F8 start up screen, but I tried a few things nothing will work. It keeps going back to the blue screen. Then I tried looking at a Windows help page that didn't help, but it did say that if someone tried to help me these numbers might be helpful :"0x4, 0, 0, 0". Can anyone help?
