How to determine the problem of loading in the absence of speaker'a?

Question

Iron

The situation is the following.
With the purchase of a 3Tb hard drive and the decision to make it bootable, the need arose for a motherboard that supports UEFI.
Accordingly, today I bought an ASUS P8Z77-V LX mother and an Intel Core i5 3570K processor.
Installed, turned on, went into the BIOS (UEFI). Selected GPU Boost, clicked Enable.

Everything. Since then, the computer can only boot and make noise with coolers.
Unfortunately, there is no Speeker on the case, there is no panel with debug codes on the mother either.

Accordingly, the question How to determine what is the problem?

Answer 1

Replace with headphones. Ordinary headphones.

Answer 2

Actually, there are two pieces of advice - either buy a diagnostic PCI board that will show debug codes (or maybe borrow it from someone you know). Or look at the speaker connector on the motherboard and connect this very speaker.

Answer 3

the speaker can be replaced with a weak diode, the desired sequence will flash

Answer 4

And the speaker - call any computer. shop and ask the speaker. Or pull from a neighbor

Answer 5

Disable boost mode and run normally. To disable and enter the BIOS: Turn off the PC and hold down the F2 key, without releasing the key, turn on the PC. Release the key only when you get into the BIOS. If it doesn't work with F2, hold down DEL.

Answer 6

Turn off the jumper (switch) of the boost on the mother
