I Just got a new H.I.S.X1950PRO REV2 agp card,it has a 3 pin jumper on it with the little cap on 2 pins.I cant find anything on it in the CD user guide or the on line guide.anybody know what its for? when I try to load a game the screen clicks on and off like its tryin to reboot,then just black but i can hear sound.then i half to hit reset....The guys in the PSU Dept.thought I could use a better PSU,so i got a 650 trio. Is my card bad? is the new PSU bad? What are the jumper pins? Im pullin my hair out,Whats left of it anyways.Can someone help? linderman,TW36. Thanks Laust....
