Question Screen occasionally goes black ?


Dec 10, 2008
Every once in a while my computer screen will go black for a couple of seconds and then come back. This is an issue with my new computer build, and installing a 12GB Nvidia GeForce RTX 3060 graphics card hasn't changed things.

You are four versions back on BIOS updates. I would update to the latest version F7b.

The system doesn't actually quit running or anything, just loses the screen momentarily? Does it do this often? Does it do it if you let it sit in the BIOS or does it just do it in Windows? Either way, I'd update the BIOS first and see if you still have an issue.

Something is completely off regarding your memory in those specs above as well. Those are more like gibberish numbers if we are talking about the amount of installed RAM

I would also make sure you go to the motherboard product page and download, then install, the latest drivers for the chipset (.inf), network adapter and audio controller. Do not rely on Windows to supply appropriate drivers. Windows may have native drivers that "work" with most hardware but they are usually not full featured drivers and occasionally create problems.

Having trouble with QFlash. I d/led the bios update, extracted it into c:\intel, and QFlash tells me it can't read the file ??

Ok, that's good. So AFTER doing the BIOS update, it is sometimes necessary to do a hard reset of the BIOS as well. Obviously it still may not be the solution you need but it IS another step in the process that we use because OFTEN it IS the solution needed.

BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for about three to five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes while the CMOS battery is out of the motherboard, press the power button on the case, continuously, for 15-30 seconds, in order to deplete any residual charge that might be present in the CMOS circuit. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP, A-XMP or D.O.C.P profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the BIOS to fully reset and force recreation of the hardware tables.
