I have an Asus KV8-MX board with a Duron 3000 cpu with 512MB ram. I know pretty cheap, but I built it 2 years ago so back off. hahaha. Anyways my problem is that at random points my computer locks up and the screen gets random lines on it and the only way to fix it is to restart. Sometimes it'll run for an hour, sometimes it won't even load all the desktop icons before it locks up. I've swapped memory and nothing changes. I swapped hard drives to a new one thinking it might be a windows/driver problem, but halfway through Windows XP setup it did the same thing. It also took about an hour to format the drive. I'm using the onboard video port which might be the problem but if anyone has any suggestions/ ideas let me know. Thanks.
