Welcome to the HP Forum.

What you are experiencing after changing the BIOS memory frequency is very unusual.

Many HP PCs don't do memory overclocking. This is also a puzzler.

Reset CMOS as follows:

Shut down the Desktop PC. Disconnect from AC power.

Depress and hold down the power button about 20 seconds, a couple of times, to drain residual MB power.

Remove the side panel. Locate and remove the MB battery. let the PC rest for a couple of minutes.

Reinstall the MB battery, reattach the side panel and connect to AC power.

Start the PC to check for a good POST and a Windows sign-in screen.

You may have a BIOS problem or a component problem if the PC does not POST.
