I have just finished building my pc with the following components; DFI DK-x58 t3eh6 motherboard, i7 920 cpu, 3gb corsair dominator memory, akasa powermax 850w, geforce 9500gt, cm690 case So i put it all together and it powers up fine, I then tried to install windows 7, which completed successfully, followed by a reboot (after the installation), then as it tries to load up windows (booting again from hard disk) it gets to the loading screen and then the screen goes blank. It does this everytime I try to load windows 7...I dont get past the loading screen. So, I tried a copy of Windows Vista Business 64bit (from laptop), this installs fine and I get into the operating system fine! Everything is working perfectly until I downloaded the latest drivers for the 9500gt from the nvidia website, installed them, rebooted my machine and I get the very same problem, the screen just goes blank after the windows loading screen. What is going on! Can anybody shed some light on this as it is getting really frustrating for me. Thanks ocuk forums Whats going on? If anybody could help me at all I would be so grateful.
