When I went to update my drivers, I used driver genius. It downloaded all the updated drivers I needed. Everything was going fine until I got to the new Atheros driver. When it went to install, the BSOD came up. And after it restarted. For a minute I thought my hard drive was toast but it booted. This is when the stuttering started.
It would happen all randomly. I'll be listening to music or/and playing League of Legends and it'll freeze for a few seconds while stuttering. Not to mention after I tried to install the atheros driver, my wireless stopped working. It was working fine with the default driver that comes with the laptop. So I looked around on the internet to find a solution. I did everything that one could think of about this issue. Defragmented the hard drive, cleaned the registry, uninstalled kaspersky and installed MSE, went and set my paging file on memory to none. So I just completely removed my wireless driver and start using my lan driver. This actually fixed the freezing up and stuttering.
At first I thought it was fixed when I set the paging file to none. But then I installed the default wireless driver again and the stuttering started back up. Then I tried to reinstall the new atheros driver.. it didn't give me a blue screen this time but my wireless stopped working again and this is the error it gave me in device manager. "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
This stuttering is driving me insane. I can't play any games like I want because it messed me up at crucial moments. And I really don't want to have to reinstall windows 7 to fix this problem. Can anyone PLEASE tell me what I can do to fix this? I need to update this driver as I believe that is what is causing the stuttering. the driver version is Atheros AR5B9.
