Hey I just built a new PC today. It was running fine the entire day and so I decided to update the BIOS and get the drivers for my motherboard (EVGA z370 ftw) from this link
Updating the BIOS worked entirely fine and my PC was still working. I downloaded the drivers and nothing is displayed to either of my monitors (using an HDMI and a display port). Also worth noting that none of my USBS work so I can't use a keyboard or mouse; I receive post code 79 whenever I try to boot up my PC. I've looked at threads with similar issues and have tried all the solutions listed there. Switching between bios 1 and 2, removing my gpu and all but one ram stick, holding the reset button on the back, and any other combination I can think of.
My full spec list is:
CPU: Intel - Core i5-8600K 3.6 GHz 6-Core Processor
CPU Cooler: Cooler Master - Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard: EVGA - Z370 FTW ATX LGA1151 Motherboard
RAM: Corsair - Vengeance LED 16 GB (2 x 8 GB) DDR4-3000 Memory
Hard Drives: Kingston - SSDNow V300 Series 120 GB 2.5" Solid State Drive
Samsung - 860 Evo 1 TB 2.5" Solid State Drive
Western Digital - Caviar Blue 1 TB 3.5" 7200RPM Internal Hard Drive
Video Card: MSI - GeForce GTX 1080 8 GB Founders Edition Video Card
PSU: EVGA - SuperNOVA G3 850 W 80+ Gold Certified Fully-Modular ATX Power Supply
Like I said, everything was working fine up until I downloaded the driver. This has been stressing me out quite a bit so any and all help would be quite appreciated.

Hello DownsMC1382,
Welcome to the forums.
I'm sorry to hear about your situation with your motherboard. So far as troubleshooting, you've done plenty so far so your options are somewhat limited. Nevertheless, have you or did you test your motherboard outside the case? this motherboard has onboard video, did you try using it?
You also want to test your motherboard without any RAM to see if the post code changes to 50 - 55 which indicate that there is no memory installed, this is just to confirm that you can get something else besides post code 79.

Thank you for the quick response! I did test the motherboard outside of the case before the problem occurred but I have not since. I have tried using the onboard video with the same result of getting post code 79. I also just tried taking out all the RAM which resulted in post code 53. I do have a warranty for the motherboard, is there anything else I should try doing before going that route?

What Driver did you download that stated this? When you updated the Bios did you First Set the Bios Back to the Default Settings? If not you should and then Re-Flash the Bios. Remember you have 2 Bios on this MB and you can change to the other Bios and test. Do you have CSM Disabled in your Bios or Enabled in your Bios? With a GeForce GTX 1080 Graphics Card you should Disabled CSM in the Bios. Debug code 79 = CSM initialization (Compatibility Support Mode initialization) that means some component you have connected to your server was not supported by BIOS Have you removed the CPU to see if you have any Bent CPU Socket Pins? Your Thread should be moved under the EVGA Z390/Z370/H370/B360 Series area of the Forum for others to review and help out. Not need to create another Thread as the Mods can more it for you.

I downloaded the driver from the EVGA website, I don't think I can post the link because I don't have enough posts yet but it is in the EVGA download center. Driver version 1.07. I did not set the Bios back to default settings. How would I reflash the Bios since nothing displays on the screens? Whenever I switch to Bios 2 I still get the post code 79 error. I am not sure how to disable CSM since I cannot access the Bios menu to begin with. I also have not checked for any bent CPU pins because the problem only began with downloading the drivers. Should I check the pins? Sorry for all the questions I am pretty new to troubleshooting issues, I never really bothered with updating motherboard Bios's or drivers before. I appreciate all the help

If I removed my current hard drives and put in a blank one would reset the Bios to its default state or is the Bios data stored directly on the motherboard?

The Bios Data Stored on the Motherboard. Sounds like Fast Boot is Enabled in the Bios, Press and Hold the Small Red Button with a small screw driver or ball pin on the I/O Shield under the Word EVGA as you Power On your Computer for a count of 5 or 6 then let go. You will then need to use the F12 Key to enter into the Bios. Driver version 1.07 or a Bios version 1.07 if a Driver what Driver is this for? I am not seeing a Bios 1.07 or a Driver 1.07 for this MB https://www.evga.com/support/download/That is for your MB 134-KS-E377-KR - EVGA Z370 FTWTheir is a Bios 1.07 for the Below Motherboards but not yours. 134-KS-E379-KR - EVGA Z370 Classified K 121-KS-E375-KR - EVGA Z370 Micro ATX

Pushing the small red button and releasing it causes the computer to turn on for a second, then turn off, turn on again for a little longer, turn off, then turn on permenately. Throughout the entire process nothing is shown the display and the F12 key does nothing.
I believe I may have accidentally downloaded the Bios and driver for the 134-KS-E379-KR - EVGA Z370 Classified K.

I just got a new result. Switching to Bios 2 and pushing the small button resulted in the computer rebooting a few times as before. But after the boot process it made a few beeps and is now displaying post code A6. My keyboard and mouse are also now lit up but there is still nothing displayed on the monitors and pressing F12 does not change that.

How well do you know the Bios Settings? I would start with Disabling Fast Boot and CSM. If you need Images I can post them for you.

I did disable Fast Boot and CSM. My computer is running once again! If I need to access the Bios menu again at some point is there some way I can without using the red button? I am using Bios 2 now so I don't know if there's some way I can recover Bios 1 to its default state just in case I need it again. Do I need to update the Bios? Because I don't really want to risk ruining my Bios 2 and then not actually having a functioning one.

Great to see you are back up and running.  When you turn on the Computer Press the F2 Fiction Key or if you have turned of NumLock in the Bios (Off) the Del Key. Some times you will need to do this more than once, I wait for the first Beep and then press and release the Del Key till the Bios Pops Up. Yes I would recommended Updating the Bios to the Current one released on EVGA's Website Also it is a good Idea to use the Red Button when you want to update the Bios because it sets the Bios to the Default Settings. Setting the Bios to the Default Settings Before you Update the Bios will save you in the End.

Turn Off Windows fast startup ... or you do not see the BIOS option, cause its NOT a Cold Boot  Remember to turn Windows 10 Fast Startup OFF, when upgrading drivers, firmware or hardware With Windows 10 there is a new “hybrid” startup mode that should cut down on boot up times.

Thanks for all the help! Just to make sure I understand correctly, I want to use the red button to reset my Bios to my default settings before I update my Bios at all? Does this include downloading any drivers or do I not download drivers and the Bios? And if I ever do make another mistake with the Bios the red button will fix it by resetting it to default correct? Thanks again!

No on the Red Button for OS Drivers you only need to use it to update the Bios on the Motherboard. Or as you had an issue getting into the Bios. Also as stated above turn off Fast Boot or Start in Windows. Remember to save a Profile in your Bios so if you have problems you can use the Red Button Enter Into the Bios and Load your Bios Profile with your Settings. You will need to do this with Each Bios Update you do.
