Do a clear Cmos. It's not impossible that playing with cable crapped your bios. Also make sure all cable are long enough and not to tight. Also that they are well plugged. If I am right your board don't have a onboard pc speaker so unless you have some that are lying at home you will need to find some. Usually the local shop will give them or sell them for like 1$ if they are cheap
😛Before going further, can I have your complete system spec please?
