The test I use is to boot from CD. I boot the newest versions of UBUNTU (see google for words that don't make sense to you), Puppy Linux or others to see if the video works there or not. I don't have to install Linux or actually know how to run Linux. I only need another OS that runs from CD to perform a fast hardware check.
Is this the beginning of a hardware fail?
