Base System Device Error on my Device Manager

Asked By 400 points N/A Posted on -


I have an Acer laptop with Windows 7 x 64 running on it. But originally, I purchased this laptop with pre installed operating system Windows Vista Home Premium. I asked a computer tech to change it to Windows 7.

It's been 6 months and there has never been any problem with my computer. But recently after a series of errors which I don't know the root cause of it, I was forced to reformat my system with the recovery disk given by the same computer tech. So far, I have reformatted my computer 4 times now. I don't think I ever succeeded with any of those processes. It always ends up with errors, freezes and hangs. Through all those formatting process, I always checked on my device manager to see if I there are still hardware’s that needed a driver.

I recognize three Base System Device under Other Devices with yellow mark on the side which means that it is not properly installed. I checked on Acer Support and downloaded all the necessary drivers and all are properly installed now. But the yellow marks are still there.

I never notice this the first time I changed my operating System to Windows 7. I just want to know if this error is important to my system and what necessary drivers do I need for this? I need advice, kindly help me. I’m not sure but maybe this is the root cause of my dilemma.

Thanks in advance.

Base System Device Error on my Device Manager


Hi Tylor Gree,

Your problem probably occurred because the driver of your CARD READER was not properly installed. For this, you have to download the CHIPSET DRIVER for your laptop.

Just do the following steps:

  1. Go to the site
  2. Choose your country and then click OK. At the top part of the next page, choose "Support" and then "Drivers & Downloads". 
  3. On the next page, select "Download" > "Notebook" > you product line and model.
  4. Choose the Operating System you are currently using and download the Chipset Driver for it.

If this doesn't work, you can try looking for the Chipset driver in the software CD that came with your laptop.

Dear Tylor Green,

In your posting you did not mention the model of your acer laptop. My answer would have been more accurate if you had given so.

Base system device refers to the card reader in your laptop. Here are few steps you can follow to solve the problem:

  1. Go to
  2. Select your product… if your laptop supports win7 you should see a list of drivers listed in the driver section.
  3. Select the download for "Card Reader" from the list of driver (if available).
  4. Install the driver.

If nothing comes up for your selected laptop, acer might not be officially supporting win7 for your model of laptop. You can try and enter the serial number of your laptop to find out if your model is supported otherwise chat with their support team at

If your model is not supported by acer alternatively you might disable the "base system device" from your device manager. This might solve your problem but the built in card reader on your laptop will not work. To do that:

  1. Right click on Computer -> Manager -> Device Manager.
  2. Right click on all devices marked yellow and select disable.

I hope this helps! Best of luck. Syed

Thank you guys for your big help. The problem occurs due to an outdated card reader driver. I installed the correct driver and the problem has been fixed.
