UPDATE:
The real issue is system crashes/freezing randomly. The moment of crashes accelerate when I run a game, but is not limited to. Sometimes my system freezes when I´m simply browsing, too.

Summary of test(result)s:
Swapping RAM slots; issue persists.
Memtest86+ results; 8 pass 0 errors.
Swapped my psu for another one (Corsair HX750); same persists.
Reinstalled windows on a new partition (formatted before installation).
Installing older GPU drivers.
Temperatures seems to be fine.
CPU; 30-40C idle (or browsing/skype); 50-60C under load.
GPU; 25-30C idle; 50-60C under load.

[strike]My computer turns on, but my monitors stay in power save mode. The monitors work fine when I connect them to my laptop.[/strike]

This issue occured today after my pc crashed, everything froze and sounds were being repeated. I had to turn off my pc using the power button (absolutely nothing responded, cursor wouldnt move, ctrl+alt+del didn't work either).

[strike]So far I tried:

  • ■ Switching my RAM with each other's DIMM slot
    ■ Placing my GPU in another slot
    ■ Removing my GPU to see if my pc works fine using my Onboard Graphics (WORKED)
[/strike]
What steps should I take now to find out what's causing my problem? Or any suggestions what might be the cause of this issue?

System specs:
Mobo: Asus Maximus VI HERO
GPU: MSI GeForce GTX 770
CPU: i5-4670k (not overclocked)
RAM: 2x Corsair XMS3 DDR3 4GB
PSU: Corsair CS750M
OS: Windows 8.1 64bit

A friend recommended me to reset/update my BIOS, but I'm not entirely sure because I'm worried that I might toast my motherboard, not sure if this is still an issue nowadays?

If the onboard video worked, but the graphics card did not, either your power supply is failing, not providing enough power to power the GPU, or your GPU died. I bios reset will not hurt anything. Look at your motherboard manual on how to do it, if you are not sure how. Just make sure the system is unplugged and has no stored up power when you do it.

Okay, I managed to fix the "no video signal" issue by taking everything apart, and putting all components back together. However the other problem still exists.
This issue occured today after my pc crashed, everything froze and sounds were being repeated. I had to turn off my pc using the power button (absolutely nothing responded, cursor wouldnt move, ctrl+alt+del didn't work either).
Click to expand...
Half an hour after I turned my pc on it suddenly crashed again. After turning it back on I got a message saying:
Display driver NVIDIA Windows Kernel Mode Driver, Version 347.52 stopped responding and has succesfully recovered.
Click to expand...
Just updated my gpu driver(apparently I didn't update it for a while now) and hope this has fixed the issue.

It has been succesfully running for a couple of hours now..
Am I safe to say my GPU isn't dead, yet? Any suggestions what might be causing the crashes? (if this occurs again)

Edit:
Critical Kernel-Power, Event ID 41, Task 63 seems to be the issue according to the event viewer, but this could be anything..?

Edit:
So my pc just crashed again, installed the chrome extension "OneTab". As soon as I pressed the icon my mouse started reacting really slow, my monitors went into power save mode one by one, everything slowed down immensily and my pc rebooted itself eventually..
My temperatures are ok, so it's not an overheating problem. CPU is around 30-40 °C, GPU is at 28 °C.

I'll be testing my pc with another PSU next monday or so, for now I ran some tests with memtest86+ and tried to simulate the crash.

Memtest86+ results:
8 pass : 0 errors

To simulate a crash I tried messing with some video settings while running a game. So I started up Team Fortress 2 and changed my adv. video settings to:
Texture detail: low
Antialiasing mode: none
filtering mode: trilinair

Once I entered a server and changed the values back to the highest possible my game stayed black for a few seconds, followed by my other monitor which went into power save mode which finally resulted in a crash (this time my pc turned itself off).
When I tried to turn it back on, it turned itself off 1 second later again, and rebooted with no videosignal.
Turning my system off/back on "fixed" the videosignal issue..

My temperatures were good. 40-50C on my cpu and gpu~. Was checking my voltage on MSI afterburned as well, which was around 1.000~1.200V on my gpu.

How likely is this a BIOS issue? Still kinda edgy about BIOS updates, so I'd like to avoid this..

If my system behaves the same with the other PSU I'll be testing with next monday, It's most likely a GPU issue?
How can I make sure it's my GPU without having to test it with another videocard? Or is that the only way?

Tried a cmos reset last night right after your post. I was able to keep my pc running for around 4-5 hours without crashing before I went to bed (also tried changing video settings etc while in-game, which didnt result in a crash either).

However, after just turning on my pc again, my monitors lost their video signal twice in a row (they restored themselves 1 second later) showing two notifications:

A bit later my system completely froze again, I was doing nothing but browsing and using skype.

Hopefully my friend's PSU will solve things.. getting rather clueless on what to do next since there are so many possibilities what's causing the issue..

Edit: I doubt it's my GPU.. I was able to play some games for a couple of hours after the cmos reset, and change all video settings without crashing (game stayed black for some seconds though..). The crashes seem rather inconsistent.
Or am I completely wrong here?

Edit 2: I hear a "device disconnected" sound, everytime I get into windows. Just heard the same sound when installing another nvidia driver version which reminded me.

Placed my friend's PSU into my system, lost video signal 1 minute after I started Guild Wars 2.. So my PSU isn't the issue.
He'll try to run my GPU on his system later today.. What steps should I take now to pinpoint the issue?
Still find it weird that I was able to game for a couple of hours after I reset my cmos.. But after restarting my pc the next day it simply crashed 20min later again.

Should I update my bios? What's the "safest" way to do this?

Well, tried running some game again after updating to the newest nvidia driver. Kept losing video signal (restored itself after 5 seconds, happened 3-4 times in a row), before it finally froze. Again. Any thoughts?

Summary of test(result)s:
Swapping RAM slots; issue persists.
Memtest86+ results; 8 pass 0 errors.
Swapped my psu for another one (Corsair HX750); same persists.
Reinstalled windows on a new partition (formatted before installation).
Installing older GPU drivers.
Temperatures seems to be fine.
CPU; 30-40C idle (or browsing/skype); 50-60C under load.
GPU; 25-30C idle; 50-60C under load.

Best result so far was from a cmos reset; I was able to keep my pc running for 4-5 hours before I went to bed. However, the issues returned when I rebooted my pc the next day.

So, my friend tried my gpu on his pc.. His other monitor also went to power save mode, also got weird horizontal black lines (height approx 2cm, they appear for less than a second) randomly while playing a game.. Except his system didn't completely freeze/shut down.
Which makes me believe there's more broken in my system than just my gpu. Not sure if a different system would be a difference big enough for it to crash or not to crash. Or am I simply being superstitious?

Is there any way to find out if my motherboard and/or power supply are broken?
I'd rather not order a new/RMA my current gpu and find out it'll get damaged again.
