Alright, I'm trying to fix this for a client and it's making me feel very dumb. After Windows starts and before the login screen, the display goes blank. If I boot into Safe mode everything's fine. GOT to be the video card/drivers right? Well.. I used 3 different video cards each in 3 different PCI-E slots. The BIOS's video setting is to PCI-E. I slicked the hard drive and reinstalled Windows. Same results. I'm hoping I'm stupid and am overlooking something obvious. Any ideas? I also tried swapping out the PSU with a brand new, higher wattage power supply.

Did you try with a different monitor? Or at least did you try with a different input? Most video cards and monitors will have many different output/input options like VGA, DVI, HDMI and displayport.

I don't think it's the video card driver, because the driver gets loaded BEFORE the logon screen. So if you loose input after you enter your password this could be something else. Especially since you tried 3 different video cards...

You said you reinstalled Windows (clean install?) but I'm wondering if you lost the display during the installation process or at what point exactly did you loose display for the first time? On first boot? Or after you installed something (like a driver) and rebooted?

You could also try to flash the BIOS to...

You could also try to flash the BIOS to latest version and after that I would also reset it to factory default.
