Is your cpu fan connected? also check the 24 pin connector if it is seated correctly

If you don't mind, resetting your BIOS may give an easy quick fix. Remove CMOS battery and reinsert.

You could always double check everything. Unless you have some really complex BIOS settings you don't want to lose, resetting it shouldn't be an issue.

Check everything again, enable fast boot possibly.

Take it all out and rebuild it again, something might be shorting.
