Hi there, i am having trouble with my pc.
About a month ago i started getting black lines across my screen when playing games, and things on the screen would not be where they are supposed to be, i Have V-sync enabled on these games, but it doesnt help one bit.
when the black lines appear my fps drops considerably
My Specs are:
Alienware M17x R2
Intel i7
6GB Ram
ATI Mobility Radeon HD 4870 x2
Any help is Appreciated :D
Also, is there any way i can atttach a video to help you see the problem that i am having?
Also, i have updated my video drivers, but nothing has changed
 
Solution
in your video card setings is v sync set for (off, on, application controlled) if its set to off it will override. also if your showing frame rates higher then your refresh rate of your monitor is another sign that v sync is not on
