Solved BIOS Not Loading, Though I Reset The CMOS.

I use a gigabyte h77-ds3h(rev 1.1). Since the beginning my pc would get stuck at the gigabyte mother board menu ( press del to enter BIOS andfew other things displayed in that menu). I could never open the BIOS though I’ve tried using all the keys in all possible ways. After about 3mins from turning the power on ( 2 mother board beeps) at the third beep windows would load. When ever I attempted to enter the BIOS my screen would go blank after the 3 beeps instead of Windows loading. I needed to change some settings, so I reset my cmos ( both by using the jumper and removing the battery) to gain access to my BIOS. After the reset windows won’t just load, and it ends up with the blank screen, with numerous attempts. I have been as specific as possible. On one of the forums advice I removed the CMOS battery for the whole night so that the charge completely gets drained. I am writing this as I remove the battery for the night. Can any of you help?
Note : I used the p2 keyboard. Used only one memory stick. CMOS battery not a problem as Windows always loaded.
