So i got windows 8 installed in my m14xr1 and here is the problem: Intel rapid storage driver would make windows freeze ramdonly every 40 ~ 120 sec and lasts about 1 min of freezing time and repeadely. sometimes it freezes at windows 8 logo loading screen so i uninstalled Intel rapid storage driver to let windows 8 use its own standard AHCI driver and it works fine... no problems with games and GPU performance. im not sure how ssd and hdd performance will be without intel AHCI driver.... before i came with this conclusion i tried testing hardware driver 1 by 1 until i got intel AHCI driver.
