Hi,
I've problem with my notebook, i already check forums, blogs, etc and still no help. Problem gone when i put sleep for a while or shutdown. ACPI.sys is the culprit (i'm checking this with Process Hacker 2). I already made a trace.

This problem happened when i played games or doing a video editing. I thought reinstall windows will make this problem gone but it still there. Already reinstall Windows 8, 8,1 and 7.
Specs:
ASUS N43SL i7 2670QM , RAM 4GB, GeForce GT540M 2GB
BIOS ver: 414 (Latest)
OS: Windows 7 (before: Windows 8.1 and Windows 8) 64Bit
