New build BSOD 0x0000124 Blue screen crash - DM log uploaded!

Did you reboot and then have graphics? The graphics card attached but not connected may have been causing a lot of the problems. Some boards, when the bios detects an X16 device will try to disable on board graphics. When you install graphics drivers, it is not uncommon for the screen to go black. It usually comes back on, but it can need a reboot to completely install and write entries to the registry. So, let me know what is happening now. Also, please click start, type device manager into the search box, click the device manager entry that appears and expand display adapters by clicking the small arrow next to it and tell me what it says. Then right click the entry, select properties and tell me want it says there. It should say 'This device is working properly'.

EDIT: When you say you installed the graphics driver, are you talking about the Intel graphics or the 450 graphics? With the 450 removed, it should not be able to install those drivers.

You can do it, but it may be the combination of the 450 drivers and the on board drivers. It seems you do have a driver problem. When the OS starts to load, that's when the drivers are activated and also when you start to BSOD or freeze up. If you have removed the 450, please go to control panel > Add remove programs and uninstall all the Nvidia graphics drivers if you are not using the card. Uninstall all the NVidia graphics drivers, but uninstall the graphic driver last. You probably have under Nvidia a HDMI driver, 3D vision driver PhysX driver. Uninstall all of them, but the graphics driver last. It will ask you to reboot, do so and see if that is better.

Also, how far along are you on this install?

I'd more or less finished the install and was just updating programmes, copying data across etc.Basically got the system just about set up. I've managed to uninstall all the Nvidia drivers and uninstalled the graphics one last - just before it blue-screened!

Edit - it's back to bluescreening as soon as the desk top loads... I wonder if a complete reinstal is my best option here

How is it running now? Is it any better, or are you having the same problems. If you are, please shut down and start it back up, when you see the manufacturer's logo, start tapping F8, you should get a screen with recovery options, choose safe mode with networking. Everything will look strange, but it is supposed to. Almost none of the programs will work, but you should be able to get internet access so you can post here. Try that if you are still having problems.
