I have a discovered a solution for alot of you out there with IRQ issues.
I believe this is causing the login freeze and black screen issue: THIS MIGHT HAVE TO BE REPEATED WITH EACH DRIVER UPDATE 1.
go into device manager- go under display adapters go into your GTX 400 series Card and see what says for
location.. E.G. "PCI bus 18 " 2.
go under system devices 3.
you will see two HD audio devices.. check them both to see which one matches your GTX 400 series pci bus
location. disable (not uninstall) the one that matches your 400 series card. 4.
check under sound devices and it should no longer be there (this step might or might not require a restart) FOR SLI SYSTEMS THERE WILL BE AN HD SOUND DEVICE FOR EACH CARD ^^ THIS MIGHT HELP TO CLEAR UP YOUR LOGIN FREEZE AND BLACK SCREEN ISSUES I ALSO RECOMMEND UNINSTALLING THE SURROUND DRIVERS UNLESS OTHERWISE NEEDED AND CHANGING THE NVIDIA CONTROL PANEL TO "SINGLE DISPLAY PERFORMANCE MODE"
(this will help with flickering) AND SET TO MAXIMUM PERFORMANCE POWER MODE
now if you want you can follow these proceedures to clean out your drivers) although you might not have to. but
it is a good idea to clean your drivers after this and steps 1-6 are a template on how to uninstall and reinstall display drivers. GOOD LUCK TO ALL OF YOU AND I HOPE THIS HELPS 1
. Download Driver Sweeper and driver cleaner and install them. mainly need driver google them. also down load the latest audio drivers from evga and the latest Nvidia drivers straight from Nvidia. 2
. boot up GO INTO PROGRAMS AND FEATURES IN CONTROL PANEL. Uninstall Nvidia Physx and Nvidia surround driver. DO NOT UNINSTALL NVIDIA DRIVERS ON NVIDIA CONTROL PANEL YET
. Reboot. Go into safe mode (press F8 repeatedly upon power up) 4
. While in SafeMode
go into program and features now selected Nvidia Drivers then uninstall them. it will then ask you to reboot the computer DO NOT REBOOT YET SELECT NO
. While still in safemode open Driversweeper select nvidia display and click analyze. when it is done click on clean. Then open driver cleaner. click on the box that says "use multiple filters" the select Nvidia, Nvida wdm and nvidia stereo. 6
. Once you have finished with driver sweeper and driver cleaner reboot back in to regular mode. open device manager and check to see if your display adapter reads "Generic video adapter" or something along those lines and that it is a microsoft driver. then check your sound drivers to make sure that All 4 Nvidia soundrivers are uninstalled.
Once you have verified that all the nvidia drivers are uninstalled REBOOT INTO SAFEMODE
. 7. WHILE IN SAFEMODE.
Go into open programs and see if there is anything labeled Realtek audio drivers if there is uninstall that. DO NOT REBOOT YET
. Open device manager and go to sound devices and select any remaining audio devices and uninstall them. then open driver sweeper and clean out the left over files. After using driver sweeper you can now Reboot into regular mode. 8
. After reboot open up device manager and make sure that all the drivers you uninstalled and cleaned out were replaced by Generic Microsoft Drivers. Then install The nvidia display drivers and disable windows automatic updates. Now reboot. 9
. after you reboot go into device manager and DISABLE
the 4 nvidia sound driver the REBOOT BACK INTO SAFEMODE.
Once you are back in safemode open up device manager and uninstall the Nvidia sound drivers. if they won't uninstall then make sure they are disabled in safemode. Reboot 10
. Now install or reinstall your onboard audio drivers then reboot.
