Windows Continues to Crash Without BSOD

[Amanda12]

Hello! For about 2 weeks now, windows has consistently hung up, crashed, and then powered off/restarted without a blue screen. This seems to happen whenever I launch a game (like Dota 2) after about 30 seconds of the application being open.

So far I've done a memory test, chkdisk, CPU stress test, cleaned out the inside and re-seated everything, completely reformatted, and made sure all temps were acceptable. I've also updated the BIOS and have all current drivers.

However when trying FurMark, the same crash happened again within about 15-30 seconds.

So I've got a feeling its the GPU going out, but I'm really not sure and don't know a good way of finding out. Could it be my motherboard or power supply as well?


Operating System
Windows 7 Home Premium 64-bit SP1
CPU
Intel Core i7 2600K @ 3.40GHz
Sandy Bridge 32nm Technology
RAM
8.00GB Single-Channel DDR3 @ 668MHz (9-9-9-24)
Motherboard
ASUSTeK Computer INC. P8Z68 DELUXE (LGA1155)
Graphics

Intel HD Graphics 3000 (ASUStek Computer Inc)
1023MB NVIDIA GeForce GTX 560 Ti (EVGA)
Storage
596GB Western Digital WDC WD6400AAKS-65A7B2 ATA Device (SATA)
Optical Drives
HP DVD Writer 1270t ATA Device
Audio
Realtek High Definition Audio

Voltages:
3Vsb: 3.41V 3Vcc: 3.38V
Vbat: 3.34V VIN1: 1.02V
Vcore: 0.96V VIN2: 2.04V
+12V: 6.76V VIN3: 0.85

Any help at all would be greatly appreciated, thanks!

Do you get the same result when you try it with the GPU disconnected and using the integrated graphics?

Now, software voltage measurements tend to be all over the place - if it's not a GPU issue, then the next place to look at is a power supply issue (but less likely if you're stress-testing the CPU successfully). You haven't specified your PSU -- which always worries me -- and junk power supplies have a way of causing a plethora of issues and making diagnoses of other issues more difficult.

The PSU I'm using is a Corsair tx650w. If it is the PSU, is there a good way I could diagnose it? Also, the motherboard I'm using doesn't have a port for me to use integrated graphics with, but I could totally be missing something.

Without equipment, there aren't a lot of good ways to actually test a PSU. Given that you actually have a legit PSU, I'm less inclined to suspect it.

My bad on the outputs - I actually assumed that the particular motherboard had an HDMI/DVI/VGA out to utilize the CPU's integrated graphics in a pinch (the P8Z68-V does). Given that your GPU is crashing in Furmark and you've essentially tested everything else (and your PSU is not an obvious culprit), that's the main component of concern. Really, the best way to test it, given that we already know it's crashing, is to test the GPU in another PC or another GPU in your PC. Or bring it to a shop and have them test it.

GPU likely, I agree.
As said, you really need to get another video card to test.

Other:
The ONLY other way I can think of to test is to burn a linux disc, or find a SPARE drive (to temporarily try installing Windows too.) and then see what happens. For example:

1) Linux:
a) Download and burn linux image to DVD (i.e. Ubuntu) for free.
b) Shut down and unhook all hard drives and SSD's (in case one is causing issues)
c) Boot to the linux DVD and attempt to surf internet or whatever... if it's not crashing the GPU is much less of a suspect and it may be a Windows software issue or drive problem.

Unfortunately since Memtest seems to work showing an output to display, I'm not sure what load level or other conditions are causing the crashing.

2) Windows reinstall method:
Similar to above:
a) Shut down and unhook all drives
b) Attach a spare drive
c) Start installing any Windows version (don't Activate if you do)... if you actually manage to install without crashing I'd suspect it's not a video card issue.
d) If you install, then perhaps run 3DMark2001 (google and get free copy from futuremark site) before installing AMD drivers... then if it works install AMD video drivers and repeat.

Install disc an use Windows 10 64-bit using media creation tool if you want:

On another PC run that, choose "..for other PC" to download the image and burn to DVD or USB as applicable.

power problems to the CPU will reset it. A good power supply will not let the CPU restart until the power is good again. This will result in a black screen and no memory dump.

power supply provides a power_ok signal to the motherboard.
cheap ones fake the signal and the motherboard/cpu reboots..

problem is going to be in the power supply or the logic on the motherboard preventing the bootup.

swap in another power supply.
the machine is pretty old, it can be the motherboard also.
