Hi. I just purchased Dell Inspiron 5567 yesterday. I observed message appearing that Graphics card has stopped working and recovered, ( Couldn't see it properly as it disappeared immediately ) Moreover, if i open any document or during web browsing, while scrolling upward or downward content/text changes it color to slightly red color, more precisely a specific portion of the page or the document changes color and while page moves u or down, it keeps happening with all the content. What should i do about it?
