Windows boots but no display

[src1425]

I recently built my son's new gaming rig for his birthday, with an Asus Maximus V Gene mobo and an HD 7870XT, and everything seemed to be working fine. Installed Windows 7 Pro, drivers, and Windows updates, rebooting periodically without any problems.

Upon giving him the new rig and setting it up, it now boots without showing the post or Windows screens. I can hear Windows starting, but there's no display. If I restart the PC several times I eventually get a display showing Windows starting up, but not the post screen, and can log into Windows normally. If I restart, however, it goes back to booting with no display until I restart several times again. I've tried updating the Catalyst drivers, uninstalling the Catalyst drivers, running Windows Startup Repair, and even using System Restore to go back to the initial Windows install with no updates. Nothing has helped. The monitor has a single DVI port, and is connected to the only DVI port on the GPU.

Any suggestions would be much appreciated.

Try a different monitor and perhaps a VGA cable instead. Also, try reseating your video card and make sure the onboard is disabled in the bios. Perhaps trying the machine with just the onboard through a Displayport or HDMI cable to see what happens as well.

Hope these help and please let us know what happens, thanks.

Can boot into safe mode?

If you can see the desktop, etc., in safe mode, the video driver may be corrupted. Remove the driver in safe mode, and set it for default drivers. Then reboot and reinstall in regular mode. (This occurs a lot in XP, so I thought it might with 7.)

It also could be that the PSU you used is just a TINY BIT too underpowered, where if the power up sequence is out of wack for a millisecond during/after POST, the video card doesn't power on correctly.

I'm more inclined to think it's an issue with it not seating properly, or a hardware issue with the video card itself.
