Is My Motherboard Dying?

I installed a GTX1080 FTW in my rig a few days ago. WoW was crashing at random, so I did some troubleshooting. CPU and GPU Temps were stable during gaming and during the heaven benchmark. So I re-seated the card, deleted and re-installed drivers, and also updated my motherboard bios. The problem kept happening. I thought it may be my PSU (from reading forums) which was a Corsair cx750m. So I upgraded to a EVGA Supernova 850 platinum. After installing the platinum my system only recognized my SSD, which had my OS on it. It doesn't see the WD Caviar Black 1tb or my optical drive. I swapped out the SATA and power cables to the HDD and also tried different SATA ports. My computer still doesn't recognize the HDD or optical drive but it did see the SSD in the other SATA spot. Any ideas?

Update: Everything seemed to be working okay on the SSD. Windows was operating normally but my computer still couldn't see the drives. Not even in the BIOS. I attempted to do a clean install on windows but it appears that it failed. I ended up saving a windows installation from another computer onto a USB drive and attempting to install windows with that. It would get hung up on 25% and then fail. After some more reading, I took out one of the two of my 8gb RAM sticks. This time the OS installed to my SSD. After this though, everything was running terribly slow. I tried to do a clean install on my GPU drivers and it failed. The screen didn't flash like normal and it wouldn't let me change the resolution. I shut everything down and plugged in the other stick of RAM and now it's giving me the critical error on startup again. I stopped at that point because I needed to get some sleep. Unfortunately I'm at work now, but would like to get back to this when I get home. Does anyone have any idea of what might be going on?

Does it sound like my GPU was just bad to begin with? Or is my motherboard failing? Did I short something out during the installation of my new PSU? I'm about to pull my hair out with this mess.

Thanks,
Austin

You don't have to replace the CMOS battery ever 3/4 yrs, because you can even run the PC without it. If like you can't save the BIOS setting, and recommend to replace it.

The 850 platinum is very good one, but don't hurt to check. You can go to the hardware monitor section in the BIOS, check the +3.3V, +5V, and +12V, you want to see those voltages should be within +/-5% range.

Recommend to test the GPU in other PC, like you said it maybe DOA.
Recommend to start over.
1) Clear the CMOS by the jumper or removing the battery, take out the gtx1080, using onboard iGPU if the MB/CPU has one ( because you don't post what MB/CPu you had), one stick RAM, and SSD with OS only to boot the PC, make sure the SSD is connected to the 1st SATA port.
2) Does the pc boot? If the PC can boot, test the RAM one by one with MemTest86 to the RAM are ok or not. You jusr run the software with 3/4 passes, you don't want to see you get the error, even single error that means the RAM is bad.
3) After test the RAM, update all the drivers, like chipset driver, gpu driver.

I ended up putting my system back to how it was before I got the GTX 1080. Everything works and runs fine except for my 1TB HDD. I did the Memtest86 and it finished without any errors. I checked the motherboard for bad capacitors and other damages but couldn't find anything. Do you guys think that I should just exchange the PSU and GPU and try it all over again? Or is there something else to check/test before I do all of that?
 

Do you try update the BIOS? because you don't post what MB you had. Also try the GPU in other PC.

I am running the latest version of bios. I have an Asus maximus hero vi with an i5 4670k.

When battery is dying, pc behavior can get so erratic, that is even hard to use it. It's better to replace it often.
And then, I had run pc 8 years on a single battery :)
