I have Dell N7110.
Sometimes , my laptop have that problem:
screen freezes. there are too many horizontal lines, which is painting and moving up and down in the screen. It is like old TV, when it can't show channels. Also at this moment, my laptop have very strange noise - like very very very old TV, it is like buzz...
That problem have for about 6 month. Sometimes it happens once a month, sometimes once a week. The last time, then this happened, I was watching movie. Laptop was not hot. now it's winter and I use additional cooling pad too! I clean and paste it too. but there is another problem...
Yesterday, I have tested my DDR3. I use memtest86+. I was testing for about 8 hours. There was no problem.
I test VideoCards also with FurMark:
there is no problem.
question: where is problem? is this caused by DDR or from videoCard? what should I do?
