Not able to boot or enter BIOS after Windows 7 upgrade

Hi all,

I just bought a new desktop with a GigaByte Z68AP-D3 Intel Z68 Chipset.

My monitor is connect via HDMI.

During its first run it installed Windows 7 Home Premium (trial version), skipping any BIOS or POST screens.

The OS is installed in a 60GB SSD. I decided to upgrade to Windows 7 Professional, so I inserted the disk from Windows and started the upgrade process using the GUI. I chose "Custom Installation" and choose to install in the same SSD of my current Windows. It gave a warning that I might lose my old saved windows items, but I proceeded.

After the upgrade was 100% complete, the computer restarted.

But it did not boot up to windows.

When I turn it on, my monitor says there is no signal -- No bios menu at all, and no Windows 7 Professional boot up either.

For some reason BIOS or POST screens are never displayed, and it seems the Windows 7 Professional installation didn't go smoothly so I can't even boot. The monitor just says there is no signal, but the mouse and keyboard do sometimes light up.

Please help me solve this problem!

  1. Try disconnecting each drive one at a time; one may still post. If you get one going, try connecting the other drive while windows is running so it is set up as a secondary drive. I clone my new drives; saves alot of time.
  2. can try dvi to see it works or not .. and then go back to hemi connector
