Question about XFX GeForce 6800 GT, (256 MB) Graphic Card
Hello all! i am having some major problems right now. at the moment i can't set my display settings above 640x480 and 4 bit color. this happened before a few days ago as well and i temporarily solved the display issues by turning down the hardware acceleration. when my husband got home he turned it back up to full and since it seemed to act fine, he thought nothing more about it. yesterday i tried to start windows and got an lsass.exe error instead of the login screen. i tried restarting it several times to see if it would work and it didn't. when my husband tried to turn it on a couple of hours later, the windows login screen came on with his first try. after teasing me for a few minutes, he restarted the computer and was confronted by the same error. we logged into safe mode and did a registry scan but nothing came up as far as there being an issue with lsass.exe. we also uninstalled the last two windows updates. after that it started up fine. then he attempted to update the nvidia drivers and instead of an error message at login, it was a black screen. so we restored the last driver to be successfully used and didn't shut the computer off :P this morning, i got my login screen fine, but i am back to this 640x480 4 bit color crap, and lowering the hardware acceleration didn't allow me to change my display settings this time. does anyone have any ideas? sorry if this has been long and rambling and please let me know if there is any other info i could give that would be useful. thanks!!
Have you run a virus or spyware scan of your machine? Is your virus and spyware up to date? While running @ 640x480 does it exibit any other errors? lsass.exe is a system process of the Microsoft Windows security mechanisms. It specifically deals with local security and login policies. This program is important for the stable and secure running of your computer and should not be terminated. Note: lsass.exe is a process which is registered as a trojan. This Trojan allows attackers to access your computer from remote locations, stealing passwords, Internet banking and personal data. This process is a security risk and should be removed from your system. Note: lsass.exe is registered as a downloader. This process usually comes bundled with a virus or spyware and its main role is to do nothing other than download other viruses/spyware to your computer. This process is a security risk and should be removed from your system. DON'T REMOVE THE LSASS.EXE let a virus/ spyware program determine if its good or bad. http://www.filehippo.com you can download virus cleaner (avast is my favorite virus protection) windows defender, spybot S&D, AdAware, HighJack This to clean the machine. Then download and install the latest drivers from here: http://www.nvidia.com/content/drivers/drivers.asp Driver Installation Hints * "Download Accelerator" utilities should be disabled when downloading any drivers. * Do not run virus protection software in the background while installing the drivers. This prevents the driver from configuring itself properly. * Before installing new drivers make sure you uninstall all NVIDIA display drivers from the Windows Control Panel. Browse to the Start Menu > Windows Control Panel > Add/Remove Programs and search for "NVIDIA Windows Display Drivers" or "NVIDIA Display Drivers" and select remove. Get back to me if none of that works. Good Luck, Tim
