I recently had a lower right pop up that looked authentic from my computer for conducting an internal hardware scan (First time this ever showed up). After running through a long list of tests, the screen began to flitter and when the test was over, several items were red. I clicked on one of them for additional info and fix, but was not immediately directed to any source. After turning off my computer and restarting it, there was no power. Same thing happened at a local service store. Is this a virus, hardware malfunction, or power source problem?
