Windows 7 extreme lag after installation of dedicated graphics driver

[heatblast]

Hey all, after a lot of pain and time wasted over trying to install win 7 on my laptop (asus gl553vd, bsod with stop error acpi not fully compliant), i tried to install win 7 on my gfs laptop which is a lenovo legion y520. It worked, with drivers injected and stuff i can run most of the drivers i want. I installed the intem graphics 630 driver which was supposed to be the hardest part and then comes the trouble. I installed the nvidia geforce 1050 driver for windows 7 downloaded from the official site and a problem appeared as soon as i restarted and right clicked the background. It took 2 mins to finally load and see the "nvidia control panel" and if i click it it takes 3 mins to load it and then everything is laggy, the mouse moves like its stuck and basically the only thing you can do is force close the laptop and headback. In the 1st reboot i didnt right click but headed straight to google chrome to find something i wanted and it lagged again after 3 to 4 minutes.I uninstalled the driver from the device manager in the 2nd reboot and everything was normal. What can i do to get it right? Tomorrow i will try to install an older driver and hope it works. Thanks

I'd see if there's a BIOS setting to turn off the onboard CPU graphics so that just the dedicated graphics is running.

Absent of that, try running LatencyMon and see what you come up with. Resplendence Software - LatencyMon: suitability checker for real-time audio and other tasks

Something else that may be an issue is if you let the GPU driver install all of its fluff instead of just the driver its self. The GPU may be conflicting with the audio. If so, it wouldn't hurt to go into safe mode and uninstall the GPU driver, reboot and reinstall the GPU driver using a custom install and opt out of all the crap except the driver its self. Don't install "Experience" and all that.

Hey, thanks for your reply, after some updates i installed, the nvidia card driver installs on its own every reboot and again same stuff going on. I used latency mon and when the cursor starts lagging as hell, latency mon just freezes without saying anything, so i guess thats not the issue.(Audio drivers are the default ones from windows 7 though so i dont know)

Edit: Theres indeed a BIOS setting which gives the option to use discrete or onboard graphics but it was "Discrete" all the time

You might want to run Process Explorer and see if you can pin down what is causing the CPU to max out which I'm assuming is the case. Process Explorer - Windows Sysinternals | Microsoft Docs
