Direct3D power cuts
I have recently replaced the LCD unit of my Laptop. Ever since then, I have been experiencing some frustrating issues.
1) Every time I run a Graphic Intensive application like a game, heaven benchmarking, or even the Windows Experience Index, my laptop just cuts power instantly. It happens when on AC or battery.
2) Every time I power down my PC, the Motherboard does not power down automatically. Windows goes through its normal process of Logging off...Shutting Down...Screen Goes Off...but then the CPU still has power (warm air blows out the cooling vent) and some indicator lights are still on. Like the bluetooth, battery, video mode, power button, etc. The harddrive and wireless card indicator lights go off though.
I have tried the following:
Update All Drivers
Reopen Laptop and check for any loose connects
