Hello so this is what's happening:
I bought a GM501GS about 6 weeks ago and has been showing since the same problem over and over again, I can be playing Destiny 2 or simply browsing the web and the screen just freezes up and the laptop won't respond to anything, to get it working I have to hold the power button and turn it on again.
The fans keep running, the usb ports stay functioning, the keyboard stays on and the loading button stops lighting completely. The sound will loop for a few seconds until it goes off (it has sometimes scared the **** out of me, it sounds like a ghost screaming when it loops). I have noticed some patterns:
-I can be using it all day and nothing happens, but when it happens, it will keeep happening about 15 minutes after I turn it on again. Until it doesn't anymore.
-When I use it in Optimus Graphics Mode (with the integrated graphics card) instead of freezing, the screen will turn black and show no image (when in Discrete Graphics Mode, with G-SYNC ON, the image will just stay still).
- It's totally unpredictable when it will happen, it will work perfectly for 3 days in a row and then suddenly the next one it freezes 4 times.
I tried mostly everything I've found out there energy-wise, all my drivers are up to date and besides that, the laptop works perfectly fine.
Until now the only thing I haven't tried is a clean reinstall but everyone who I've seen who has had this problem that didn't work for them at all.
It might be the OS, as I've read that other people have encountered some issues while running Windows 10 on a SSD, but I'm not an expert so I can't be sure.
I hope you guys out here can help me, this is really annoying and I can't do anything without expecting that already.
PS: It froze while writing this.
Are you using latest bios?
how is your temp before freezing?
Although I don't have your laptop, I have GM501GM version which is working fine (I did repaste with LM and fresh install windows though...)
