I was trying to overclock my cpu, I over did it and sent it into a boot loop. It eventually re booted but after it shut down it won’t post anything. I’ve tried resetting my cmos by using both a jumper and by removing the cmos battery. I then tried to set my bios settings back to default and still nothing

system hardware:
Mobo:gigabyte 970 gaming sli
Cpu: amd fx 4.0mhz
Gpu: radeon rx 580
Ram: 16gb 4x4 ddr3 1600 MHz Corsair xms3

Full procedure. If this doesn't work, then you've damaged something. That would be incredibly rare though unless you were getting way out of hand with the configuration.

Don't skip any steps. Follow the directions EXACTLY as outlined.


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 five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes, press the power button on the case for 30 seconds. 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 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 hardware tables to reset in the boot manager.

It is probably also worth mentioning that for anything that might require an attempt to DO a hard reset in the first place, it is a GOOD IDEA to try a different type of display as many systems will not work properly for some reason with displayport configurations. It is worth trying HDMI if you are having no display or lack of visual ability to enter the BIOS, or no signal messages.
