I recently built my own computer and installed Windows 7. Recently the computer won't load the OS automatically when i power it on. If i want to start Windows, i have to press F12 to enter the Boot Menu and select the Hard Drive specifically and then Windows 7 will boot and work perfectly fine. My Motherboard is a Gigabyte 880GMA-USB3, and in the BIOS the Hard Drive is selected as the first boot device. I have a Antec 550 watt PSU and all of the devices power up correctly and function fine. So my question is how do i get Windows to boot automatically without having to go into the boot menu every time i turn on my computer?
When i push the power button, the computer posts, loads the BIOS and then sits with a black screen with a flashing white underscore cursor. If I let it sit like this, nothing changes and it unresponsive to any input. I does not give any error messages or beeps to indicate anything is wrong, it just fails to boot Windows on it's own.
I've tried multiple (at least a dozen) times of turning off and powering on my computer to see if it will load Windows on it's own with no luck. I've tried unplugging all unnecessary hardware (Graphics card and DVD drive) to see if they affect the loading process, but still no fix. This problem started after i left the computer on overnight installing a huge amount of updates for drivers and the OS. This problem was not present when i first installed Windows 7 and when no drivers were installed on the computer, this being the first time ever the computer was powered up. When Windows is loaded, it does not give an error messages as to why it does not load automatically.
