Solved Output is lost but computer still running

Various / CUSTOM BUILT
May 21, 2016 at 07:28:38
Specs: Windows 10.0.10586 Pro, Intel i7 4770k, 32GB 1600MHz RAM
This has never happened before, up until today (five times already).

I was sitting at the computer, when all of a sudden all my screens turn black and seconds later they start searching for a source, indicating that my GPU no longer is giving output. Along with this, the computer is still running (as in, all fans spinning and lights on and green) but is frozen (or something, people on skype say I was disconnected from calls). One time I pressed the reboot button on my mobo, the computer just shut down all the way and didn't power up again.

I've checked all cables running between my monitors and PC, they're all working just fine.

Anyone know what's going on?

If the system has been assembled for two years I would suggest you try re-seating all cards, RAM, and cabling. When dealing with the RAM, many times the contacts are composed of two different metals. This can cause oxidation to occur. You can clean the contacts on the RAM using a pencil eraser. Then snap each RAM stick in and out 4 or 5 times to burnish.

While inside the case it would be a good time to blow out all the dust/dirt using canned air or an air compressor. DO NOT use a vacuum cleaner, which can damage electronic due to static discharge.

Be sure to also blow out the power supply thoroughly from both ends.

Check all the voltages in the BIOS. 12V, 5V, 3.3V. All should be within +-5% of rated numbers.

You didn't post any specs so it's impossible to determine if it's a hardware compatibility issue. It could be a problem with the power supply, or the graphics card (if you have one), or overheating. It could also be a software or driver issue. More info is needed.

As riider stated, more information is needed. Your title indicates custom built. Your processor has a GPU included. Are you using that, or an add in graphics card?

Idle temps in celcius according to SpeedFan

GPU 1: 41
GPU 2: 53
System: 43
CPU: 128C (I highly doubt that this is accurate)

I haven't overclocked anything.

Did you build it yourself?
Check if the CPU cooler is properly installed.
Thermal paste used?

I built it myself yes. Been using it for more than two years now and never experienced this problem. CPU and cooler is properly installed, with thermal paste.

EDIT:
It just happened again, so I decied to take a look in the event viewer. There are no warnings, errors or critical errors listed that could relate to this. Only critical one I could see was a "kernel-power (41)" which I assume is because I had to forcefully shut down the machine.

Take a careful look at the CPU cooler and see if it possibly has came off its mount and is even slightly loose. This is rare but possible and would explain a lot.
Also you should get 4 core temperatures.
Try HWMonitor and see how that reads your temps.

You have to be a little bit crazy to keep you from going insane.

The cooler is tightly attached on all 4 mounts

Core idle temps:
Core 0: 49
Core 1: 47
Core 2: 45
Core 3: 47

Just experienced a BSOD too, PAGE_FAULT_IN_NONPAGED_AREA

Could it be related?

When did the problem start?
Have you recently upgraded to win10?
Installed something new?

You could possibly have a failing RAM module. It would explain the symptoms as failing RAM can cause peculiar behaviors.

First, while the PC is powered down and removed from any power source try reseating the RAM modules and even cleaning the edge connectors. A recommended way of doing this is by using a pencil eraser on the metal contacts.

You can also try running the built in Windows Memory Diagnostics tool. Click on start and type mdsched then hit enter. Select from the options. Typically the longer the scan runs the more comprehensive the results.

A third way of diagnosing RAM problems is by removing half the RAM modules and performing some labor intensive tasks. Swapping them around and doing the same again. If the problem(s) persists one way or the other you will know if RAM is the problem.

mdsched found no errors

Trying out the two other methods now


sluc, Started two days ago, been using Win10 since aug. last year. Only installed a couple of games off Steam recently, nothing big.

Sorry I assumed this was a Windows 7 PC not Windows 10.

It is possible there is a software conflict.

Is this an upgrade to Windows 10 install or a clean install of 10? If it's an upgrade there could be a possible software conflict somewhere. There are still kinks being ironed out with W10, especially through their upgrade path.

It's an upgrade. I have too much stuff on my SSD to bother with a clean install. (I have reinstalled Win10 a couple of times though, using the option where it keeps my files and docs)

I don't have adequate tools at hand to mess around inside my case atm. I'll take a look when my exams are done and I get my tools.

I did a quick reset of the computer which seemed to fix the problems temporarily.

EDIT: Seems like a factory reset didn't solve anything. The issue persists.

I sorta live out in the middle of nowhere so I can't get canned air anytime soon, I also don't have my anti static wrist band here, which I perfer to use when tinkering inside my case.

Just reseated all connected hardware and wiring as well as removed dust.

I can't seem to make my motherboard post. CPU fan doesn't spin at all, GPU fans start up but stop again before even making a full revolution. All lights are green, and I've followed the motherboard manual to ensure everything is wired correctly.

I've also tried starting up with nothing but the CPU and motherboard power connected, as well as with one, two and four RAM chips connected, in multiple configurations. No results.

I had that situation a month ago. MB died. Changed with similar MB and used with existing hardware. All good again.

It also started with frequent BSOD. Decided to cleanout the box, which was indeed very dusty. After assembling, nothing happen on power on. The cpu fan would make an attempt to start.

I made it post by taking it out of the case and running it on a table

After that I just disassembled my entire machine and reassembled it, it runs fine now. I don't know if it fixed the black screen/freeze issue. Time will tell.
