I got a GForce FX5600 128 mb and replaced my GF3 ti200 64mb thinking it would markly improve gaming. And guess what, i had to put it back in the box. Now im back to my previous card which is functioning ok. The thing is i like to use the new one bec. i spent a good amount of money for it. Here's the problem and the remedies i made: Games randomly lock-up. I updated moboard drivers, video drivers, tried disabling in-game settings, etc. to no avail. However, with the GF3ti 200, everything is ok. There has to be something that the new card isnt reading right, right? My specs are as follows: ECS K7AMA2 (Via chipset) moboard w/ integrated sound, AMD Athlon XP 1600, 512 RAM. These more than meet the system specs stated in the box. Some say its the power supply (i have 300 watts), some say the moboard, since it only supports 4x while the GFfx5600 is 8x which is unlikely accdg to tech people. I cant even begin to speculate. I refer to this forum and its good members for assistance. Thank you, any advice is most welcome.
