installed bios v5 and nvidia gfx card driver, after restart noticed boot time went from 6 secs to 1min and 30 secs. noticed ram was in 2t mode so switched it to 1t and pc wouldnt power on. just 2.5 second beeps every 5 secs. after disconnecting hardware one by one beeping stopped when i uninstalled vid card. finally cleared the cmos with the jumper and got it back running. so im guessing the issue is the bios, which version should i use? cpu is winnie
