jude, start with an external monitor and see if it does the same. If it does not, then it is part of the LCD circuit that gives you the trouble. Check your LVDS cable, your inverter (unlikely) and finally your LCD panel. It sounds like the issue is with your video card (integrated part of your motherboard) overheating GPU IC or solder connections around the GPU that becomes lose during usage due to eat. A reflow might help. Hope this helps, good luck.
