Why does my GIGABYTE 945 motherboard have black frequencies?

I don't know if you have added an independent network card? And has there ever been such a situation before? I've seen such problems caused by current motherboards with Wake-on-LAN.

The integrated graphics card generally does not need to be shielded, because the interrupt priority of the graphics card of the PCI slot is higher than that of the integrated one, BOIS will automatically detect, as long as the independent graphics card is plugged in, the integrated display will be automatically blocked under normal circumstances, otherwise there is a problem with the independent graphics card, after the integrated display is blocked, you have to reply to BOIS, otherwise the computer will have a black screen.

Connect the cable of the display to the integrated display interface and then turn it on,After booting up, you should be able to see the system desktop when you enter the system display,Then set the graphics card as the main display in the properties and then OK,Restart the display cable to connect to the independent display,This should be OK!

Could it be that the hardware is loose? . . I've come across ... It's actually a loose hard disk interface cable.

Is it a black screen all the time? Can you hear the normal tick of the motherboard's self-check? Or can I get into the system with sound interpretation?

There may be a problem with the motherboard, go check it out.

...Same with mine ... It's a graphics card issue. Then go and see, there is a problem with the motherboard and you can't hear the sound entering the system. I think you can change the cable to see.,If it doesn't work, take it to repair the graphics card.。。

Problems with memory sticks keep ringing. Your problem should be that the power supply, monitor, or graphics card is not properly connected.

You check whether the interface of your graphics card is not in good contact, unplug the graphics card, wipe its interface, clean it if there are traces of oxidation, and then plug it in. If not, you can try a power supply with 8 phases.

The graphics card may be loose Unplug it and press it again.

There is a problem with the hard drive There are bad areas

It has nothing to do with the startup item.,Put the inside of the host.,A small battery is deducted for 30 seconds.,Put it in.,All settings are restored to the initial settings.。

If you don't have a system installed on your new computer, then install the system.

If your computer system is already installed, then the current phenomenon is that you can't enter the system. There are several scenarios:

The first situation is that the hard disk is not booted due to poor contact, sometimes the phenomenon is the same as not installing the system, sometimes just like the cursor flash you are now, the solution is to confirm that the hard disk cables are plugged in.

The second scenario is when the boot settings are incorrect. The new machine installation system sometimes needs to change the boot order, such as the USB disk setting first. After installing the system, you don't change back to the hard disk for the first boot,In the case of plugging in the USB disk that can't boot, you will have this situation,The solution is to temporarily unplug the equipment that is not used on the main chassis,Try to boot,Plug it back one by one after normal。

Or there is no hard disk boot in the BIOS, try the default settings of the BIOS.

The third situation is caused by system failure, which is more common on old machines, although new machines rarely have system failures, but it is not completely impossible. The judgment method is to unplug the hard disk after confirming that it is not the above two faults, and if the screen appears to let you insert the system disk English prompt, you can determine that it is a system failure, and reinstalling the system is the easiest way.

The fourth is that the hard disk is broken, the phenomenon may be the first or third, because the system is installed on the hard disk, so the hard disk is broken, the system is broken, and the new machine has a warranty, contact the dealer.

Did you try it out when you bought a computer? In this case, you can try to redo the system, if the system is still like this, find the place where you install the computer, let them test the hardware, don't delay the time, after the replacement you will be in trouble.

It may be a quality problem with the motherboard, take it to a repair shop and take a look.

If the heat dissipation is not good, change the heat sink.

Memory. GIGABYTE motherboards pick memory.

Mine is okay to change the graphics card, I thought it was a graphics card problem, only to be sure that it was the memory to blame.
