hi all,
My 8800GT dead, bought a gtx650 01G-P4-2650-KR install the driver come from the CD 314.07. It boot up normally, I play game for couple second then screen when black. Restart the computer it still black and I download all 10 different driver from nvidia for GTX 650 and none of them let my window boot to desktop in normal boot, alway black screen after windows 7 logo disapear. Reinstall a fresh windows 7 and it still same thing happen to both of my computer.
 
Motherboard: GIGABYTE GA-P35-DS3L LGA 775 F6
Memory: Crucial Ballistic 2GB
CPU: Q6600 2.4Ghz
Power Supply: Corsair 620HX

Bought a new GTX650 and reinstall a fresh window 7. Everything boot up to the desktop and I install my motherboard driver such as chipset, lan and sound card. On my Device Manager, Display adapters it say: Standard VGA Graphics Adapter show, I immediately download the latest driver from nvidia 347.25 WHQL, check a clean installation. Display adapters change to NVIDIA GeForce GTX 650, I then restart the computer, after the window 7 logo gone my screen when black. I can go all the safe mode without any problem and If i delete the GTX650 driver it let me boot to desktop in normal mode with generic Standard VGA Graphics.
