Well im having same problem with gl553ve (1050 Ti). I ve sent my laptop to asus service to repair it. Now I got it back and again my GPU sometimes dissapearing, games freezing -_- I doubt ill buy asus again...
Don't upgrade to 305 it is not the version for your GL553(VD) it is the the GL553 but another number instead of (VD). Asus told me it was a fail that they had send it to Microsoft database. And they says thanks to me.
Sympthoms you can get:
- Higher temps
- Inaccessible Boot Device (You need to reinstall the computer)
- Blue Screen Of Death
- Hardware failure.
