PC emits sustained beep but still boots

[GregB99]

My friend turned on his PC today and it won’t stop creating a high pitch beep.

We have tried the ram modules one at a time, one of which wouldn’t boot on its own. The bios reads these both fine and doesn’t state any problems.

Tried disconnecting the DVD drive and the secondary HDD with no luck.

Also tried blasting the GPU and ram connectors with compresssed air.

The PC still boots and runs totally fine.

Any ideas?

Look in your motherboard bios for something like "Halt on : no errors" change that setting to halt/prompt on all errors. See if that helps.
