Question

Possible CPU crash... or something

Sep 17, 2017 5:43AM PDT

For the past month I've had a problem that may be regarding my CPU... I think. When I'm playing a graphically demanding game it will after some time make my computer crash. This has happen with three graphicly demanding games (My setup met the system specs still) and one time after I turned the computer off and on again I get this screen:
https://ibb.co/mQV355

I have two types of crashes: one where my monitor will shut off and I'll hear a fan in my computer starting to blow like crazy leaving me no choice but to turn off the on/off switch to turn the computer off, and one where (this is the type of crash that happen the most) my monitor will shut off if I play a game but this time I can still hear the game from my headphones and there have been instances where I've had a youtube video on while playing and I can still hear the video when it crashes, and my fan won't go crazy like with the other crashes. I have to press the on/off button but when I come back to my desktop the folder layout is different, I have to rewrite my password when I log in to Steam - something I normally don't have to do, almost as if my computer has "reeboted" in some way. For a time the first type of crash was the only one that happened and it would happen after about an hour if I had maxed settings and it doesn't usually happen when I lowered my settings. The second type sometimes doesn't even take more than a few minutes regardless of the graphic settings.

It's worth mentioning that I have also just had to get a new graphics card graphics card recently because my old one crashed (right before I had this issue). My PC was built in the summer of 2014. This has never happened before. I've tried cleaning the insides of my computer twice with a can of compressed air but it didn't do much. I tried with thermal paste and it didn't help. I don't know what has happened lately that have created this annoyance.
Here's how much memory and CPU my game can take up: http://imgur.com/Q4Lua7v .
My SSD is SSD 120GB Samsung 840 EVO, Basic. My CPU is Intel(R) Core(TM) i5-4670k CPU 3.40GHZ. My motherboard is an MK ASUS Z87-A ATX Z87, 1150. I've got A-Data 8 GB RAM DDR3 1600Mhz/CL9/XPG and my graphics card is GeForce GTX 780 (same as the one before). All this on a Windows 10. My case is Kab Fractal Design Define R4 Titanium Grey.
I did the GPU stress test with a program called Furmark for 12 minutes. The highest my Intel (R) HD 4600 was 80° C (https://ibb.co/gy4QBa ) and my 780 went probably up to 72° C (https://ibb.co/husdWa ). I also did the CPU Burner for about 10 minutes and my CPU went up to 82° C.Here's a picture of my computer from the left side with the cover on and two with the cover off:

Clarification Request
You cleaned it but
Sep 17, 2017 8:59AM PDT

Did you try replacing the CPU heatsink compound and checking the CPU fan after this work?

About 1 dollar of compound so not expensive as things go. YouTube has many videos how to do this work.

Heatsink?
Sep 19, 2017 7:09AM PDT

I'm afraid I don't know what a heatsink is

This is where Google and YouTube shine.

In about 10 to 60 minutes you'll know what you need to know.

Okay, so I now know that heatsinks keep the CPU from getting overheated. However I still don't know where to find it on my computer as I don't seem to have those big metal things they resemble. Is it underneath my CPU Cooler?

Heatsink
Sep 22, 2017 3:17AM PDT

The cpu cooler is 2 parts.
One part is the fan the other part is the heatsink.
The heatsink is what sits on top of the cpu chip.
Normally and aluminum thing with fins.

Crash

Since you have a K model cpu if you have any overclocking going on set it back to stock.

Your first link shows the bios saying you have a hot cpu.

Start with getting the heatsink and fan nice and clean.

It's not uncommon for the heatsink to become clogged with dust so you may need to remove the fan to clean it.

Leave the side panel off and watch the cpu fan make sure it spins up quickly.

New problem
Nov 12, 2017 2:18AM PST

Hey, now I can't start my computer. I was playing a game with a friend of mine and in the middle of it the game froze and I got the crash where the fan blows. I held the on/off-button until it turned off but now when I start it again I hear the fan blowing like crazy and nothing starts on the monitor.

Most BIOS'es show something on the monitor. In that case, there's a hardware error (CPU, motherboard, graphic card) when you see nothing.
But some might not show anything and wait till Windows displays something. In that case, it could be a Windows issue.

Only you know what's different now compared to what it was. But my guess is that you'll have to replace the graphic card.

It's the graphics card
Nov 18, 2017 2:52PM PST

Well, today I changed from my new graphics card to an old one and my computer turned on and I haven't had the crashes throughout this day. I suspected it would be the graphics card, even though I didn't see that graphics card have fans attached to them. In two weeks I'll see about getting a new graphics card

what's the power requirement of each?
Nov 18, 2017 6:22PM PST

It's possible the old graphics card is just under what the PSU can provide and the newer is just over it.
