Re manuals it is easier to go to the Gigabyte website, they tend to have good archives: <a href="http://www.gigabyte.com/products/product-page.aspx?pid=1877#manual">http://www.gigabyte.com/products/product-page.aspx?pid=1877#manual</a> The only light on the motherboard is a power led which is bottom right, clr_cmos is just below the FDD port.
