Hey guys,

I'm in a real pickle here. Whenever I boot up my PC, nothing is displaying. Windows doesn't come up, the BIOS splash doesn't present itself, nothing. Just a black screen. I want to give as many details as possible, but I understand that it may be a little long-winded, so I'll break my post up into three parts: the story of what I was doing that lead to the problem, the problem itself, and the troubleshooting I have tried. Any help or advice you can give would be GREATLY appreciated. Let's get started with what happened:

THE STORY:

So yesterday I had some spare time, and decided to fully backup my important files and restore my PC to like new, and also use the opportunity to install a few extra harddrives. Here's my setup:

Windows 10 Professional 64-bit
Gigabyte GA-Z97X-SLI (rev 1.2) motherboard
16GB Vengeance DDR RAM (1600MHz)
Intel i7 4790K @ 4.0Ghz
EVGA GTX 980 SC
256GB SSD (OS drive)
3TB HDD (game drive)
3x 2TB HDD in RAID5 (music/picture/video/documents drive)
Corsair H60 liquid cooling
Corsair 850-watt PSU
Dual BenQ 2420Z monitors through Display Port.

So at first I backed up all my important files, and then restored Windows 10 Pro. It all went fine. Windows booted back up just fine. I added in the new 3x 2TB HDD, and installed AOMEI Partition Assistant (just personal preference), and formatted and wiped the new HDDs and my old 3TB drive. I just wanted to start fresh and wipe the drives before creating the RAID. That all went fine as well.

I then used the opportunity to update my BIOS. I noticed that I had been running version "F7", and the latest BIOS version on the Gigabyte website is "F10b", which was a beta BIOS, but it was the most recent revision, and was put up 3/3/2016, and I figured if nothing newer has come out in a year, it's probably stable. So I used Q-Flash in the BIOS and updated the BIOS. That all went fine, and I noted that the BIOS did in fact list the new BIOS revision. I spent some time looking around in the BIOS just to see if there was anything I wanted to change while looking for the RAID configuration settings (hadn't really messed around in this mobo's BIOS before). While poking around, I decided to disable the Intel graphics. I didn't think this would hurt, as I use my EVGA GTX 980 SC for my video output. I'm not sure if having it enabled reserves some of the processor's resources even when not in use, so I figured I would just disable it.

I then changed the HDD settings from AHCI to RAID. I then found the RAID configuration utility, and tried setting up the RAID5 of the three 2TB HDDs. When setting up the RAID, I had a Smart event/alert/activity/whatever on one of the drives. Now, this didn't startle me as I was actually re-purposing these drives from a 4-drive NAS unit where they were previously in use (I just figured I would throw the drives in my PC rather than use my NAS at all), and I knew one of the drives had failed, but I wasn't sure which one. That's why I was using 3 drives instead of 4. So I shut down the PC, and swapped out the bad drive with the other spare drive.

I then booted on the PC again to finally set up the RAID, when I noticed a couple of my fans weren't spinning. I figured I must have accidentally unplugged the fans while swapping out the HDD. So with the PC being on, I took off the back side panel, and noticed that I indeed did not connect the bottom and front air intake fans. So I plugged them into my PC case's speed controller (which also powers them), and they lit up and spun up just fine. I know it was bad practice to plug the fans in with the PC being on, but I figured with the power going through the chassis's speed controller, which gets IDE power from the PSU itself, I didn't really run a risk of shorting anything. Now, something you should know about my case. I have the RAIDMAX Scorpio V mid-tower case. At the time I thought it was cheap yet stylish, but let me tell you, it is a nightmare for cable management. There is nearly zero space in the back for extra cable storage, and that makes putting on the back side panel a nightmare of squeezing and pushing. So, while my PC was still on I kept trying to slide the panel on, but I just couldn't do it. So I shutdown the PC, and flipped it on it's side (the would-be glass panel side, but I had that side panel also off). With gravity working with me, I was able to push the back side panel on. I flipped the PC back upright, and turned it on, which leads me to...

THE PROBLEM:

So now that everything was connected just fine, and everything had previously been working, I then turned on my PC. However, nothing was displaying on the monitor. All I receive is a "no signal" message. No BIOS splash screen, no Windows, nothing. I notice that my top fans (air outake) which are linked to my CPU fan header speed up and slow back down every 20 seconds or so, almost like it keeps trying to boot. I was very concerned that NOTHING was displaying.

The motherboard has some decorative red LEDs which all lit up. The GTX 980 lit up. The hard drives spun up. Just nothing was displaying.

So I tried a few things to get it working...

MY TROUBLESHOOTING:

Well first thing I did was a power cycle. I powered down the PC, flipped off the PSU switch, and unplugged the power cord from the PSU. Plugged it all back in, turned it on, but nothing.

I then tried replugging in the Display Port cables on the video card and the monitor. Nothing.

I tried unplugging the new HDDs I installed, as well as ALL HDDs (including my SSD with Windows) in hopes that it would force the mobo to just boot to BIOS, but nothing.

I tried disconnecting the video card, RAM, and all cables running to the motherboard (CPU power, mobo power, front USB, etc) and reconnecting it all, but still nothing.

I tried taking out the GTX 980 video card, and connecting an HDMI cable to the motherboard's HDMI out, but still nothing.

I figured maybe the video wasn't coming out of the on-board HDMI port because I disabled the intel graphics in the BIOS, so I figured resetting the BIOS config through clearing the CMOS would fix that. So I powered down the PC, and taking out the motherboard's battery to clear the CMOS. I kept the battery out for nearly an hour and then put it back in. That didn't work. So I read in the mobo's manual that touching these two prongs on the mobo with a screwdriver shorts the battery and clears the CMOS. So I tried that, but nothing.

I also tried multiple monitors, and multiple video cords (both Display Port and HDMI).

CONCLUSION:

I feel like I've tried literally everything I can think of aside from requesting an RMA with Gigabyte. I bought the PC from CyberPowerPC back in spring of 2015 (they had a sale at the time, and the price difference between buying the parts individually vs their pre-built was a matter of $20). So I'm not sure how Warranty would go... I'm not sure if I should contact Gigabyte directly, or go through CyberPowerPC. Through CyberPowerPC, I have a 3-year labor, 1-year parts warranty. I really do not want to ship off my whole PC if it's just an issue with my motherboard. I'm not sure of the warranty I have on the motherboard, but I believe Gigabyte offers 3 years on their mobos.

Any advice, help, or suggestions you can give me would be greatly appreciated.
 
Solution
I ended up figuring it out, through some dumb troubleshooting solution. I figure I'll post what happened here in case anyone in the future comes across this post.

I ended up plugging in a motherboard speaker to check for error message beeps. I was hearing continuous equally-spaced short beeps, indicating a PSU failure. This didn't make much sense, as everything appeared to receive power (fans came on, motherboard lit up, HDDs spun up, etc.). Anyways, I grabbed another power PSU and plugged it into my motherboard. After turning on my PC, I was still receiving the same continuous equally-spaced short beeps. Well, I knew this PSU was working, as I just pulled it from another PC. So the PSU failure could not be the problem.

At...
Any BIOS update for that motherboard past F7 is for "Broadwell" Microarchitecture 5th Generation CPU. The Intel i7 4790K is a 4th Generation "Haswell" Microarchitecture CPU.

Starting with F8, BIOS prohibits updating to earlier version BIOS.

You might consider replacing the BIOS Chip with one that has the F7 BIOS. I don't believe this kind of anomaly is covered by any warranty. Offical BiOS versions past F7 clearly state 5th Generation CPU. Beta BIOS is for something elase.

Any risk flashing into a BETA BIOS?

After turning on my PC, I was still receiving the same continuous equally-spaced short beeps. Well, I knew this PSU was working, as I just pulled it from another PC. So the PSU failure could not be the problem.

At this point, I was very defeated. I decided to call Gigabyte tech support. Once I got through, the Tech asked me to pull out all the RAM and turn on the PC with no RAM. Of course the PC did not turn on, but the error noise from the motherboard speaker changed to a continuous long whine, indicating a memory failure (duh). He then instructed me to insert just one of my 8GB RAM sticks. So I put one stick in the first DDR3 slot and turned on the PC. Voila, it turned on just fine and displayed video. We were curious that perhaps the second stick of RAM was bad, so I turned off my PC, pulled out the one stick, and put in the other 8GB stick. I turned on the PC, and again it turned on just fine. So then I turned off my PC, and put the 2nd stick in as well. I turned on my PC again, and it worked just fine.

So I have no idea why that worked. I reseated the RAM probably 8 times myself before calling support. Somehow starting the PC without any RAM, and then trying to start with just a single stick somehow reset things I suppose. Screwy stuff.

As for Calvin7, thanks for that info on the BIOS updates. I didn't read much on what was all included in the BIOS updates other than what was on their website (http://www.gigabyte.com/Motherboard/GA-Z97X-SLI-rev-10#support-dl), and all I noticed was "better support" for 5th gen BIOS, and "fixed memory compatibility". So I figured updating the BIOS wouldn't hurt. I mean, it booted just fine several times after updating the BIOS. Even now that things are working it is booting just fine with the F10b BIOS. Hopefully nothing bad happens in the future.

Hello. Well, I’m going through the same problem here, same board (ver. 1.1, running F8 BIOS two years already) but from a different origin. I installed a new M.2 drive into my PC and had some problems cloning into PCIe storage. I had then 2 or more bootable OSs and was getting into BIOS a lot just to change boot order and saved. Suddenly, the boot drive selector started showing corrupted drive names, a full wide row with a repeated symbol instead of the drive name. After several more changes the board started having problems to boot. Some power cycles and it showed a message that the configuration was causing problems, so I loaded setup defaults and it rebooted but didn’t get to POST. Started clearing CMOS and then reseating everything and nothing helped. So I decided to try one memory DIMM at a time and voila, it started. Swapped DIMMs to confirm a damaged memory but it started anyway. Put both back together and it started. Solved I thought. NO. A couple restarts later I was removing a DIMM to get through POST again. So I installed both DIMMs and run a memory torture test at default settings and at XMP (2.4 GHz) and everything run just fine. Memory isn’t the problem, it’s the BIOS having corrupted settings every time I save settings into flash. Too much flash write cycles? Buggy BIOS?
I have just flashed the same F8 UEFI BIOS into my ver. 1.1 board to see if that helps and I’m wandering if you had any further problems since?

The same thing has happened to me. It was recommended that I update to latest BIOS, which was F10b ... Now, motherboard no longer posts with video. Is there not a way to recover the original BIOS, using MSI's backup BIOS feature?

Help!

Got this MB on ebay, and I'm getting exactly the same problem. Tried EVERYTHING. Were you able to get yours working?
