Hello,

You're welcome, it was our pleasure.
Have a good evening.

Good evening,

What drivers should you be aware of before knowing which ones are outdated?

It is labeled in the device manager as network controller and unknown device.

After downloading a driver, the network card was installed, and I now have access to the internet via Wi-Fi. However, I still have this unknown device, and I don't know what it is.

In the properties of this unknown device, try to get the identification number.

Thank you very much, that was indeed it, but now I feel like the computer is slower, I thought the latest driver would solve this issue, but on top of that it seems to be refreshing, and all actions are not smooth and we can see the choppy movements. What should I do?

Do you still have any question marks in the device manager?

No, but I think it is possible that the computer did not detect a device, like the graphics card, because I find that I don't have much detail about it.

If there are no more question marks or exclamation points in the device manager, does that mean the graphics card driver needs to be installed?

Look in the graphics card and see if everything is okay.

Humans are at their best when things are at their worst.

It just says Intel(R) HD Graphics
The name of the graphics card is not listed.

Reinstall the video driver:
For --> 32 bits
For --> 64 bits

Human beings are at their best when things are at their worst.

I thank you infinitely, everything is back to normal!

Hello,
Do you have the names of the devices for this computer?
In the control panel, at the top left of the window, there's
"view by"; click on small icons, then click on system which should be among the last icons represented by a blue screen, click on it and go to device manager in the blue column on the left.
Check if any of the devices are marked with a yellow exclamation point; if so, the driver is not correct. Remember when downloading a driver to include "Windows 7 Pro 64-bit" in the search if it’s for the Dell Vostro V130 since it is installed with Windows 7 Professional which is 64-bit.
By the way, I add that for downloading free software, it's the same; you must specify that it’s a 64-bit operating system.
I reinstalled the Region's computer (Dell), so if you need drivers, I can tell you their download names.
Good luck.
