I've upgraded to windows 8 about 3-4 weeks ago and it's been crashing almost every day ever since. I updated bios, changed to default settings, updated all drivers, checked memory with Windows Memory Diagnostic (it ran for over 24 hours), changed the power supply and even formatted the drive and installed a fresh copy of windows yesterday and still no change.
There is no any help from windows 8 website or forums. i think you guys has probabaly encountered the same in windows 8 and i am waiting a fix for this.
thank you for your sincere help in advance.
