have a Hercules 3d Prophet Geforce 2 Pro with 64 Mb ram on my system. My problem is that when a play demanding 3d games upon changing resolution (loading a different level for example) i get multi colored vertical lines on my screen and the computers comes to a hard locl. The only thing to do the is hard reset My motherboard is an Asus P2B-DS running dual pentium III 700 Mhz. I really think that is a hardware problem and has to do with the AGP voltage that the motherboard supplies at the AGP port but i am looking for some other opinion. My chiplet is the Intel BX and of course the card runs on 2X AGP. Also i have noticed that when playing an opengl game this type of crash never happens.
