I am running Windows Vista.
Today while I was browsing the net as usual I was shocked to see that my computer screen darkened and everything appeared again in a few seconds, but after a few more seconds the blue screen of death appeared, as shown in MakeUseOf post here: http://www.makeuseof.com/tag/four-funny-ways-to-prank-your-parents-with-the-family-computer
My computer restarted immediately. I could not read the details. Now it’s working fine but I am afraid that there is a problem with my windows. How can I find out the problem to stop my operating system from damage and myself from a heart attack?
