It's always good to scan for malware or viruses. However, I think this just might be the case of some odd driver issue. If you do not have an anti-virus program, then download Avast! Free. It is pretty good and I have been using it on my PCs and laptop (a total of 3 systems) for the last 4 years. I think I only had 2 or 3 virus during that time period on all systems combined.
Another good program to use is Malwarebyte's Anti-Malware. There is a free version (which I use) and a paid version. The free version has limited capabilities like you need to start a scan manually and you must also update manually as well. But it is free and it is good.
