We recently had to reinstall the operating system on our computer, now, there is purple dots on our screen. Is this a problem computer or a monitor problem?

We have a Dell Dimension E521and Dell monitor using NVIDIA drivers.

Hello

I suggest to update your graphics driver using Windows Update or download the driver for the Dell Web or NVIDIA site.

This problem may be due to graphics driver or overheating.

I hope this helps.
