Windows 7: Completely blank screen after Windows logo, can't login

Completely blank screen after Windows logo, can't login

Hi guys,
Let me start off with the specs – this is a custom build:
Windows 7 Home Premium 64-bit OS
Gigabyte GAH61N-USB3 mobo
Intel i5-2400 CPU
4GB Crucial Ballistix Sport DDR3 1333 RAM
1TB 5400RPM 2.5" HDD
MSI N620GT-MD1GD3/LP GeForce GT 620 GPU
Slot-loading CD/DVD±RW optical drive
Dell 2208WFP 22" LCD monitor, hooked up on DVI

The problem I'm having is that on bootup, everything looks fine and runs normally until the logon screen is supposed to come up. After the initial Windows loading logo, the screen goes completely black and then the monitor falls to sleep. Nothing will wake it up, and I can't connect via VNC either so I think the computer is hanging at that stage.

However, in safe mode, the logon screen comes up fine and I can login and everything works properly. In device manager, the graphics card shows up properly, but when I go to the screen resolution settings, it does not display the name of the card.

I have tried switching to VGA and that doesn't work. My BIOS is set to PCIE graphics primary, onboard graphics secondary. The onboard graphics work properly if I disconnect the graphics card. All the drivers for the graphics card are installed and were working before this started.

I have tried reinstalling the drivers but that didn't help. The only thing that temporarily worked was to disconnect the graphics card, uninstall the onboard graphics drivers, and then restart and reconnect the graphics card. However, after I restarted a second time, the problem reappeared and the screen went black after the logo.

I'm pretty much desperate here; reinstalling the OS from scratch is going to be way too much of a hassle, especially with the amount of applications I use. Any help would be greatly appreciated!

Thanks,
JGAN

Are you sure the dual monitor 'hook-up' is correct?

I only have one monitor.

Also, I uninstalled the Nvidia drivers in safe mode and that fixed the problem. However, when I went back to install the latest version, it started again. Is it a driver conflict here?

Hi JGAN,

It seems a video driver issue with the system. If possible please check with different versions of video driver as it is a possibility that latest one might not be compatible to any of the applications installed on the system.

Also, let us know if you have installed any new application or hardware on the system before this issue started occurring.

You can also perform a system restore if it was working fine earlier:

Hope it helps.

I tried every single driver supplied by Nvidia and none of them worked. Could the card be bad?

Hi JGAN,

Thanks for your reply. As different drivers also cause this issue and you have checked and it works fine onboard graphic card, there is a possibility that it is a graphic card failure.

Please check with a different graphic card on the system to confirm this resolution. If you have any further queries feel free to reply to us.
