new GA-Z77-HD3, the internal graphics seem to seem to work (mostly) ok, but if i plug a graphics card in, it will work the first time, then after a reboot it will only show the startup graphic before the screen goes black. The odd thing is that even though the screen is black, the backlight will cycle on and off every few seconds.

if I start in safe mode it works ok

same behavior with NVIDIA 8400GS and AMD HD6670

same behavior with different monitor

same behavior in either PCIe slot


edit: solved

- start in safe mode
- in device manager deleted display driver
- restart normally (comes up ok, just like first time start after install card)
- install latest driver
