[SOLVED] horizontal lines on my display, what could it be?

[Chriss Angeh]

recently ive been getting these horizontal lines that are like white translucid, like it was some kind of interference i guess you could say, on my screen whenever im playing something intensive it spikes up, but when i quit the game the screen goes back to normal and if theres any lines during idle well its quite minimum that you can barely notice it.
its been raining since yesterday and this happened today so i dont know if its related.

Probably video card issue, overheating or failing. Need to list system specs and check temps while the system is under load.
