Sleep mode after BIOS update

[IsaacNewtonovic]

After recent BIOS update. My PC goes into sleep mode every time I play a game. I cannot revert it back to the old version, it always says "unable to identify signature". Is it even possible to do a BIOS rollback or are there any other solutions?

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Start with a hard reset to release any excessive static on the PC:

• If Windows is open, click Start and then Shutdown.
• If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.
• With the power off, disconnect the power cord from the back of the computer.
• With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.
• Reconnect the power cord and turn on the power.

Attempt to reset or recover the existing BIOS (if the recent update was interrupted): Click here (restoring BIOS on notebook: http://support.hp.com/us-en/document/c02693833)
