Hello!
Recently I bought a new laptop ACER v3-571G manufacturer number NX.M67EL.002 - with no Windows pre-installed. After installing a Windows 7, I immediately had problems with Atheros wireless drivers - it could barely connect to the wireless network (most of the time when i start up Windows i need to go to the device manager and disable-enable Atheros network adapter and after this step I have no connection issues until I restart laptop). I have tried different methods and ended up by writing everything HERE: PROBLEM with Atheros WiFi connection - Acer Support Community
As I reinstalled Windows (which is written in that topic) I still had BSOD: DRIVER_POWER_STATE_FAILURE 0x0000009f
The i5 2nd cores' 2nd thread goes to 100% usage and my laptop seemingly slows down - at that moment I cant open a new programs, but can work with already opened. After some minute or two the OS is crashing
The main questions are:
It is a problem in software or hardware - do I need to send my laptop to the warranty repair?
Could it help if I buy Windows 8 and reinstall from my Windows 7 or it can be repaired on my old OS?
Thank you in advance!
I have added the SF_Diagnostic_Tool zipped files as attachment!
