I have had a geforce fx 5600 made by jetway I think and I recently had my system crash out on me, windows xp would not start, so I formated and reinstalled but now the text on my boot up screen is a little odd, there are pixels missing from the letters for example CPU ATLON 2500 is kinda artifcated and when windows has loaded its in low colour mode and shows as VGA and wont let me install any detinators. any info peeps?
