I have an Asus K53SC laptop, running Windows 7 Ultimate. My issue is that my laptop freezes, followed by a total black out (the laptop is still running, but I can't do anything, even the cursor disappears, and if I have a sound on background it repeats the last 2 syllables forever). Sometimes it occurs without a freeze, just my monitor turning black, and other times I get a blue screen. What I've seen during my troubleshooting tries is that whenever I don't get the blue screen (when only the monitor turns black), the event is not recognised as a crash.
This occurs when I browse the internet, most of the times when I watch a video, having pictures loading in the background, gifs, it even occurs when I'm watching movies (or playing games, it occurs while playing) and alt+tab it. Another thing I observed is that it occurs more often when running on High Performance/Entertaining Mode, while when on Battery Saving it only occured while watching movies or playing games.
I have tried to reproduce the problem in Safe Mode, but for some reason it never occured.
Initially, it was only occuring when I was alt+tabbing games, now it expanded to all other situations I previously mentioned.
The only thing I can do afterwards is to force restart the laptop (power button).
OS:W7 Ultimate 64 bit
Processor: Intel® Core i7-2670 QM CPU @ 2.20 GHz (8 CPUs)
RAM: 4 GB
Graphics: Intel HD Graphics 3000 (I also have a Nvidia Geforce GT 520MX 1GB, but I never find it mentioned in my specs)
I hope someone can help me, any ideas are welcome, I'm desperate.
I suspect a GPU problem, but meh, what do I know.
I hope I posted in the right section.
Thank you in advance.
