I'm not fully sure what the problem is, the video signal either freezes or cuts out completely. It's been happening for a while, but I've been away from my computer for a few days, today it worked perfectly fine for a time. When I started playing a game, the problem came back.
OS: Windows 7 Home Premium SP1
CPU: Intel Core i5-4440
MOBO: MSI Z87-G45
GPU: Asus GeForce GTX 950 2GB
RAM: Corsair XMS3 8GB (2x4GB)
Drive 1: Samsung 850 EVO 500 GB SSD
Drive 2: Western Digital Caviar Blue 1TB HDD
I have not overclocked anything or made any modifications.
All parts are a little over 2 years old, except for the GPU which is just under 1 year old.
Specifically what happens is, when this video signal crash occurs, the audio stutters for a moment, and the screen completely locks up, it then stays frozen or goes completely black, then I hear the error message sound. I can't read this message, and I haven't found a way to recover once this happens. Audio still works, and as far as I can determine the computer is running just fine, just without the video signal after this occurs, it even plays the logoff jingle if I hit the power button. I don't know what specifically triggers it either, but it seems to be related to high load on something. When I try to reboot, the video crash usually happens shortly after, so once it gets messed up it consistently does so until things have been resting for a while so to speak.
This started around a recent windows update and Nvidia driver update, but I don't know that these are related to the problem. I've tried two restore points, as well as DDU, I've tried using an older Nvidia driver that I know works, I've tried reseating the GPU. I really need help determining the cause, or at least seeing that error message that I can't read.
