Yes, it is a possibility, but it could also be a possibility that another "piece" of the computer has failed.
IF, you have another processor you can swap out, you can try that and once again try powering on.
If you have any add-in cards ( pci cards ) I would remove them completely and try powering on.
If you have done these two along with replacing the power supply, you chances are very good that the motherboard itself has gone bad and will need replaced.
