I have Gigabyte P35-S3 rev1.0 motherboard and I was running F4 bios on it and I wanted to update its BIOS to the latest version 'F8' but when I flashed it to F8 then it became unstable so I cleared CMOS and Boot into Q-Flash utility and updated my BIOS to F7 but these BIOS also didn't allow to boot up Windows so I again cleared CMOS and boot into Q-Flash utility and updated to 'F6' BIOS but these BIOS just killed my system and now I am stuck at startup splash screen and I cannot boot into Q-Flash utility because it hangs at splash screen and no keyboard key works. I tried clearing the CMOS by removing battery and putting a jumper as I did earlier but this time it won't work. Any help would be appreciated.
I already tried disconnecting several resources like Graphics card, Hard Disk, Rams etc and also clear CMOS but problem didn't solve.
Intel Pentium Core2Duo E6750 2.66GHZ
Graphics Card: nVidia 8800GT
