So, lately weird line flickering appeared, occasionally, it's about 80% of height, 1px width (supposedly) and 40% from left side of screen and about 12% from top of screen. It flickers once in some time in almost a blink, but it's noticeable when screen is black or white. (percentages, as to what I think, relatively based on screen size)

First I thought it was because of game, insufficient RAM or something (I've got integrated VCard) so I didn't care much.
Then it appeared in Microsoft Office PowerPoint 2013, well, my presentation is filled with pretty professional goodies, like, I really made a huge file with a lot of effects to make it look pretty and to explain certain IT topic to total "noobs" (beginners).
I didn't give a crack before either. But THEN,
I put my laptop in sleep mode, after 10 minutes, I start my laptop, the Windows 8 screen shows (the one with blue Windows logo and white circling circles) and it flickered again. After I log on, I write this message, it hasn't appeared since.

NOTE: This is not a computer with external screen! This is a LAPTOP with BUILT-IN integrated card and BUILT-IN screen.
