Blue screen of death after using new UHD monitor... please help

[ZahFox]

Ok so recently I just built a new gaming PC. I spent a lot of money on it, and it has great hardware specs including a GeForce GTX 1080 GPU. The rest of the specs I'll post at the bottom of the post. I've been waiting for my monitor the last few days, so in place of it I've been using my new PC on an HDTV in my living room. Everything has worked just fine until now. For my rig I bought the Acer Predator XB271HK bmiprz 27-inch IPS UHD (3840 x 2160) NVIDIA G-Sync Widescreen . When I hooked up my PC up to it using a displayport cable (so that I could utilize the G-Sync feature, everything worked fine for a while. Then I tried playing some games on Steam, and after about a few minutes my PC crashed. When Windows starts to boot I always get the blue screen of death now with various different messages usually being KMODE_EXCEPTION_NOT_HANDLED, IRQL NOT LESS OR EQUAL, or SYSTEM_SERVICE_EXCEPTION. I've tried switching the boot mode to legacy and going into safe mode, i've tried recovery install, and sometimes I can even login and make it to my desktop for a few seconds. But eventually no matter what I do it crashes to this screen. I spent a lot of money on all of this and I'm very scared.. Someone please tell me what I should do...

Go through this guide. ALso, make sure you are plugging the monitor in teh GPU, not MB.

Another useful and immediate test would be to remove your GPU and boot off of teh onboard graphics to see if you have trouble.

This did not help. I tried taking apart my computer and carefully reconstructing it, making sure everything was put together and connected correctly. I also tried booting without using my GPU. The same errors occurred. I can't reinstall windows or do anything in safe boot, because they all eventually lead to some for of a BSOD. I finally tried to just do a clean install of Ubuntu (over Windows not alongside it), and my computer froze during the install (of course...). After this, my computer no longer boots! It will turn on and get to the first screen where it says hit F12 etc. but I can't do anything and it will either continuously reset or be frozen on this screen. I feel completely doomed..

Somethig is definitely not right. Bench it, that is, take it out of teh case and put the MB on the box it came with. Reinstall in it just the CPU and cooler + one stick of ram. Then connect the PSU and monitor/peripherals and boot it by using the special button it has. See if you can get into teh BIOS.
IF you can, start addind stuff to it one by one and booting it until you find teh point of failure. In this order:
- the rest of the ram
- sdd
-hdd
- gpu

Don't despair. We'll get to teh bottom of this.

So I was doing this earlier, although I did forget to remove the the SSD when I did this, but I feel like this isnt the problem. I spent hours trying all kinds of things and eventually I just gave up and I've dropped it off at a local computer repair shop. I feel like they wont be able to help though, last time I went there they ended up charging me around $70, solved nothing, and I still had to fix it myself. I'm suspecting that I need a new motherboard luckily I have a warranty. When I was testing my new monitor by gaming in 4k graphics mode, is when my computer started getting BSOD. I also noticed that only one of my front case fans was plugged in (theres usually four). My CPU and GPU fans were working, but not all of my case fans. Do you think my motherboard got too hot and got ruined that way?

Something is definitely wrong with your computer.It can be RAM,motherboard or hard drive,try to replace in sequence to find the culprit.

You woudl put my money on teh MB beeing bad aswell. NOt from overheating. Just defective. You couldn;t have caused this unless you've messed with the BIOS(overclocking etc.)
Unfortunately, these kinds of things can only really be tested beyond benching teh system by replacing parts with ones you know are good. So i guess thtat's where computer shiops come in.

It's hard to damage motherboard even by overclocking, but as I said before just check and find culprit.
