Welcome to TSF.

Clear CMOS.

Check the standoffs between the motherboard and the case.
They have to match the motherboard's mounting holes exactly - no more, no less.

You can also try taking out all of the computer parts and re-seat the bare essentials which are: power supply, motherboard, cpu, ram, and videocard.
