I have a sony vaio. When the laptop is cold and has just been turned on everything looks normal. After about five minutes the screen starts to mess up created red and blue horizontal lines where the screen is changing such as if i expand something then minimize it.
So far i have deleted and created a new partition and am running xp pro. i have updated bios, video, and mobo chipset drivers. Also when i connect to external monitor it displays the same. if it is hot, on restart before the os has loaded there is also the same problem. i’ve got 512 ram and Pentium M 1600mhz. i’m pretty sure it’s a mobo problem since the vid card is intergrated. i can send screen shots if that helps. (you can see the problem in the screen shot)
