Many thanks for looking into this issue further. The file was freezing my PC as well
So in the end it is same annoying ACPI.sys? I was hoping the xperf analysis can point to a particular driver, saying, look, here is the bastard,
update it/remove it!!!
Well, I have done all the operations before: updated BIOS to latest 412 version, changed power plan as well as numerious features inside it (also tried uninstalling Asus Power4Gear Hybrid), and my laptop stands on a comfortable stand while I lay in my bed
- no conditions for extreme tempertures (I also monitor temp: CPU 75, GPU maximum 65)
I am falling into despair.
SOme other observations: when I play on integrated Intel HD 3000 video (yeah its powerful enough to give e decent STALKER picture) the porblem does not happen. It only appears when I switch to Nvidia Geforce GT550m (I have the latest drivers here). Subjectively it now seems to be an overheating issue with Nvidia as why the heck it starts after at least 10 minutes of play but never at the very beginning? Or could it be the Optimus issue?
Also I would want to change setting inside BIOS, but it's a rather a grap than a normal BIOS - AMI BIOS from American Megatrends - it has almost no features to change: no chipset features, no power management to say noting of the ACPI settings.
Thannks, Nitroshift as well for your suggestion. I tried removing battery with no effect. Only reboot (not always) and going into hybernation help to unlock my CPU.
ANy other suggestions/experiences?
