I own an ASUS laptop and for the past weeks I have been getting increasingly more and more crashes, in many forms:
The first kind of crashes I keep encountering is probably the most interesting: At a random moment, the GUI will stop responding, but the mouse cursor keeps refreshing on the screen. I never had any audio playing in the background while this happened, so I have no idea if the background processes actually do keep running when this occurs. Going on with the explanation: When this happens, I usually get about 15 seconds of mouse movement joy before the system completely freezes. If I click in that period, it seems to make the complete freeze happen faster.
What is interesting about this is that earlier today, the GUI froze and I just moved the mouse a little. Upon seeing that, I decided to wait a bit. After about 20 seconds, the computer continued to run. That did not last for long, though, and it did finally crash minutes after.
The second kind of crash I get is having my computer freeze in the middle of anything (be it watching a movie, saving a file, compiling one of my projects, minimizing a program or switching between applications), instantly. The audio buffer repeats itself, the mouse immediately stops responding.
The third kind of crash involves the classic BSoD. This one happens the least amount of time, and it always reports a Watchdog timer violation. WinDBG reported the analysis as being inconclusive.
- For the past year, I had been getting random video driver crashes. The 3rd last time I reinstalled (genuine) Windows, it was because the screen was scrambled.
- Sometimes the laptop just shuts down instantly, without freezing or any other symptoms - just like someone unplugs it from the wall, without a battery attached.
- It cannot be the HDD, as I upgraded to an SSD recently, and I did a fresh Windows install.
So, what do you think? Is my motherboard toast?
Thanks in advance for your help!
Update: While proofreading this, my laptop froze again and I had to manually restart it. It was the first kind of freeze issue I described. This seems to happen mostly while I am not doing anything at all. I was at the Global Game Jam this weekend, and my laptop has not really been kept idle. It only froze once there. When it does not get any input, however, (like when reading something) the crashes seem to happen more frequently.
