| Your situation | Recommendation | |----------------|----------------| | PC works fine | No – Do not update. | | New CPU not recognized | Maybe – If you find the exact correct BIOS. | | Random crashes/freezes | No – Likely hardware (capacitors, PSU) not BIOS. | | Security concerns | No – H61 is too old for modern security guarantees. |

If still dead – BIOS chip needs external programmer. | | Update utility freezes | Wait 5 minutes. If frozen – you likely have a bricked board. | Before flashing anything new, back up your current
