Hi all, New here to TechSpot and am in seriuos need of some help with my laptop. I have an Aleinware Area 51-5700m, Windows XP, Mother board is the Uniwill P71EN0 with a 2.0 Intel Pentium M and a nVidia GeForce 6800Go (NV42M) 256 Mb DDR I (MXM-PCI Express) GPU My problem is that when I boot up I get vertical lines throughtout the boot image and then a garbled up bios, and Windows will not load. My question to you, Is this my GPU or motherboard causing this failure. Also, could this be a cause of overheating? I have been doing numourous searches on this issue and have found nothing. I can't even find where I can purchase a new GPU. Any help would be appriciated. Thanks.
