Hi, I bought a new laptop and it has been encountering a series of BSODs. I'd been through similar threads for the resolution of error. Could someone please analyze the dump files I've uploaded to Sky Drive and let me know the root cause ?

It seems that there is no valuable information in the mini dump. If you want to analyze the kernel dump, please contact our CSS for further assistances. BSOD or freeze issue can be caused by the crash of the processes which are running in kernel mode. These processes can be hardware drivers or antiviruses. You may boot in Clean Boot Mode. Perform a clean startup to determine whether background programs are interfering with your game or program If the issue persists in Clean Boot Mode you can try to check the driver signature. To do so, in Start Search box enter sigverif.exe. Then click the start button in “File Signature Verification”. In the result list, please pick up *.sys files, rename one of them and then shut down or restart to check if the issue still occurs. If the issue persists, rename another *.sys file listed in the result of driver signature verifying, and check result again. By doing so we can determine which un-singed driver is the root cause. Another way is enable muni-dump and use Windbg.
