I've recently bought a new laptop (like 2 weeks ago) and now the screen completely freezes randomly, the only thing I can do is press the power button to turn it off.
I can't really find a pattern, sometimes it freezes while just browsing the web, but it does happen more frequently when playing games it seems. I also had a BSOD twice after turning it on again with the error message "Invalid process atach", I'm not sure if it's relatad though.
Also I have the feeling the fans blow harder before a freeze, so I kept an eye on my cpu and gpu temperatures, gpu peaked at 65°C and cpu at 75°C. It should be able to handle hotter temperatures so I don't think that's the problem?
I'm runing windows 8.1 64bit, intel I 7 4500u, Nvidia Geforce GT 740M 2GB.
