9400 Gt Blackscreen

[Brandigler]

Hello recently about 2 weeks ago I just did a simple restart and after all I got was a black screen, nothing had been changed before the restart. After a while I found out it was being caused by the driver I can go into safe mode and remove the driver from device manager, after a reboot comes up just fine but windows 7 automatically installs the 9400Gt and then I reboot and bam the black screen is back. I have tried installing old drivers and new drivers in safe mode but it always ends in the black screen, my mouse does not show up, tho sometimes the bottom part of the task bar shows up and a few times my background and icons have showed but then just froze like before. Also maybe unrelated my usb keyboard will not work until I boot the system, so I've had to pull out a P/s2 keyboard. I also know my system is old I'm looking to upgrade within the next few months but for now I need a computer.

 

All I've gotten sofar is it sounds like a dead graphics card. Just wanna make sure.

full system specs.

Ok so I was looking this up for you and might have a solution

 

Its possible that your graphics card is changing the screen resolutions and/or refresh-rate to something that your monitor cant handle. Seems the most logical as your system was working fine until the driver update and driver updates do silly things like that

 

Ok so restart you're computer and press F8 to get the Windows advanced menu boot and choose "Enable VGA Mode".

 

Load into Windows, right click on the desktop and select "properties", select the tab "Settings" and pick a really low resolution like "1024x768" and press the "Apply" button (but don't reboot yet when asked to). Next press the "Advanced" button, then select the tab "monitor" and change the monitor resolution to "default" or 60Hz.

 

Now restart your system and see whether Windows will boot normally. If so, you can change the resolution and refresh-rate back to you preferred values. Whenever you pick a too high resolution or refresh rate the screen will turn black again, but don't worry, don't press anything and just wait 15s, after which Windows will roll back to the previous setting

 

Let me know if that helps
