Black screen at win7 login - GTX 550Ti - Audio drivers conflict ?

Hello guys

Doing a lot of video editing with Premiere & Effects, I would like to install a Nividia GTX 500 Ti I bought recently (to get power from GPU / CUDA).

Issue:
When installing NVidia drivers, at first reboot everything is fine (HD resolution is active), but if I restart, I get a f**** black screen at windows logon screen (no signal from monitor)

I think it's a conflict between NVIDIA and my audio drivers, because everytime I succeeded to get the HD resolution after install, it was after disabling / uninstalling audio drivers (see Investigation part below)

Hardware config:
- Motherboard: Gigabyte Z87-HD3
- Power supply: Corsair VX 550w
- RAM: 16Go DDR3
- LCD monitor on DVI port
- TV screen on HDMI port
- Audio outputs:
- SPDIF coaxial for TV external sound manager
- onboard jacks to desktop speakers
- Other: SSD + HD drives

Software config:
- Windows 7 64b up to date
- BIOS is up to date
- All drivers are up to date

Investigations:
I spent 3 full days on the issue with many tries, including a fresh reinstall of Win7, but everytime it ends with a black screen and a loss of video signal

I used Guru3D DDU tool to remove properly the drivers under safe mode
I tried different drivers (4 different NVidia, 2 different Realtek, default drivers from Microsoft)
I tried disabling onboard audio option via the BIOS

I did almost all combinations between disabling or uninstalling Nvidia or Realtek audio drivers or devices
Sometimes it went black after first reboot, sometimes it went good at first boot but then went black on further reboot no matter I disable / uninstall any audio driver or device

I get no errors in device manager
I plugged / unplugged monitor cables, waited for 20s after switched off/on the DVI monitor

Hardware seems fine (fan is spinning and I get the default VGA output), my overall hardware is recent (almost one year)

I really don't know what to do next ... so do you have any idea ?

 

i had the same iisue with my 480gtx , exactly same issue . i think our gpu cannot take load anymore , its partially dead. will work w/o drivers installed though

 

brother, exactly my story.

i was working with premiere pro n suddenly all black , gpu gets hot n fan works normally.

moniter shows no signal

 

Well, I don't think my GPU is dead since it seems to work correctly right after installing the drivers (I mean I get the HD full resolution and NVidia panel is working well).

The issue is that if I reboot, I get the f**** black screen (probably due to drivers conflict).

Sorry for your loss anyway

 

I don't know if it is going to help you but I had a similar problem with my 680 where I would get a black screen after a reboot (when it was fine after reinstalling drivers) that I solved by unchecking and hiding in windows update some "Intel HD WMMD drivers" which kept installing and messing my gfx drivers.

 

I finally fixed the issue by doing the following steps:
- Remove audio drivers
- Install Nvidia drivers WITH audio drivers
- Go back to Safe mode
- Disable audio drivers in device manager
- Reinstall audio drivers
