I have bought a new motherboard to support my new Gtx 970 which the oem motherboard doesn't support, additionally I bought a 2tb Seagate hardrive.
After installing all the new hardware I was unable to get any video output so I removed the Gtx 970 and got a signal through the motherboard VGA. I tried to launch windows from the old HDD and it freezes at the point the 4 RGBY dots appear on the screen and then will reboot asking me if I want to start windows normally or launch startup repair. I have no System images and want to keep the data on my HDD so startup repair doesn't seem too helpful.
I've also retried booting windows with the new HDD unplugged, swapping sata ports and only 1 stick of ram to no avail.
