Many laptop owners skip the yearly cleaning and start to see this bluescreen after a few years.


There may be a software issue but my cure rate with simple cleaning leads me to ask this.

The malware issue is worth noting as well. I like Grif's advice at;forum-threads

If those don't pan out, research the EVENT VIEWER and see if more clues are there. If there is something you are doing such as playing a video game, be sure to note that.
