There's a Clear CMOS jumper on the motherboard on the motherboard that you can move to reset the CMOS and clear any BIOS settings.

Since you appear to have a video card, have you removed the video card and connected the monitor to the integrated graphics?

It originally came with Windows 7 Home Premium 64-bit.

If you go here, then scroll down the page, then click the + in
Clearing the BIOS settings
there will be pictorial instructions on how to clear the CMOS.
