I have a 650 Duron, 256MB Ram, 40 Gigs Seagate HDD, CD-Rom Sony 52X on a MSI MS6340 mainboard(KT133) and a MSI MS8117 GF2MX videocard. My monitor is a 15" AOC. I am runnig Windows XP and with every version of nVidia's detonators i get a high refresh rate at 1024x768 on Direct3D aplications (OpenGL works fine) that my monitor can't handle it! I tried every piece of drivers(beta, original, tweaked) and no solution. I tried with another card (GF256) and the same problem. Reinstall windowsXP and the same problem. I tried using the latest version of VIA 4in1 drivers and no solution! I tried even the refresh rate fixer (from this site) and the problem remains. If anyone have a clue or have dealed with the same problem please tell me what to do. And pls no tips like: Upgrade your monitor(no $$$ right now for that)! Thanks a lot!
