Acer Aspire A515-57G, laptop crashes every time saying error with pre-istalled McFee antivirus

Kaz24

Hi,

I recently bought the Acer Aspire A515-57G and have been having a multitude of issues with it. First of all, I had DPC Latency issues which caused audio issues and microsoft support could not find a fix for the issue, so I then had to reset the laptop. After this reset, I tried to plug in my audio interface (focusrite scarlett 2i2 4th gen) and the laptop crashes every time saying error which has something to do with the pre-installed McFee antivirus. After doing this, I was unable to open file explorer at all as it kept crashing. When trying install the drivers for focusrite the laptop then crashed due to MFC140.DLL. I have just reset and am experiencing the same crashes. I have no idea what to do and would like some assistance as I have been getting help from microsoft support but it has not fixed any issues.

With the Focusrite Scarlett 2i2 4th Gen. you need to configure the correct audio drivers, which should be ASIO and not the other flavors (which I think are MME, and Windows DirectSound). Audacity doesn't support ASIO drivers, Mixpad does. Instructions for setting up MixPad to use ASIO drivers is here: Choosing Your Audio Settings. Other factors are ram as you need to upgrade to min 16GB but 32GB would be much better, try all that as it should work on the Aspire A515-57 laptop, btw I'm using the same laptop and this laptop is an excellent allrounder. Good luck and hope this helps you out.

The other possible issue with your laptop is that it may be running other applications (programs) in the background which are using up the computer's resources, namely CPU cycles and memory (RAM). Some D.A.W.s even come with a CPU and RAM meter so computer resources can be monitored during recording or mixing.

To check, you can hit crtl-alt-delete on your keyboard, and then select "Task Manager." Under the "performance" tab, it will show the CPU usage and RAM usage. Under the "applications" tab, it will show all currently running applications. You should be able to close any applications you aren't using, like email or "groupware" like TEAMS or Slack.

Laptops also can have power (battery) saving features, one of which is purposely slowing down the CPU to extend battery life. I recommend when you're recording or mixing, that your laptop is set to "high performance" mode in the "Power" section in Windows' control panel.

Yeah I have 16gbs of ram on an 12th gen i7. Everything should be running smooth. I use FL by the way, I just don't understand how it is running so poorly. I also use the focusrite usb asio.

Try to uninstall any 3rd party Antivirus software.

We have seen multiple reports of BSODs on some Windows 10 & 11 systems when using our driver with McAfee antivirus installed. This crash is due to an outdated virtual driver from McAfee called mfehidk.sys.

When experiencing this crash you will see either of the following error messages:

mfehidk.sys or KMODE_EXCEPTION_NOT_HANDLED

You can resolve this issue by using the MCPR tool to uninstall McAfee and all related drivers. You can then install the latest version of McAfee from your account.

High DPC latency is a.o. caused by a 3rd-party firewall, Power Plan Advanced settings, 3rd-party programs/bloatware backing up to Cloud, programs/apps running with High Priority at the background and Network settings. Insufficient RAM, outdated Windows version, BIOS and rogue drivers also slow a system down. The first think you do with a new laptop is, as advised above by the others, uninstalling all the bloatware, trial versions and 3rd-party AV (use their uninstallers, not Windows) and browsers. Change the custom power plan to Windows default power plan settings and uninstall Hibernate and Fast Startup. Then update Windows11 to 23H2 build 22631.3296. Do a full charge cycle to register the battery capacity in BIOS and run Storage Sense: The temporary bin at the bottom left may still show gigabytes of legacy upgrade files (like OldDos), delete all redundant Windows update files. Run Dism.exe /online /cleanup-image /restorehealth and after completion SFC /scannow after each Windows update. There are excellent system Windows maintenance guides on this forum and on Elevenforum that I can recommend.
