major card problems



New Member
i have a ati all-inwonder 128 card. i just formatted my computer on sat and have been having this prob ever since. If i turn my graphic accelertation all the way up or to the level b4 full my computer monitor either freezes or dosnt view a picture after a couple minutes of usage. The background show 2 or 3 lines that look messed up there not that big thought. But if i keep my graphic level down to the 1 or 2 level im fine but i cant play games watch dvds or play games. What is going on here. My screen size is 1024*768 and im using true color. my refresh rate is set to optimal too. Please help
