Problem with my Chaintech geforce fx 5700 ultra

my Chaintech geforce fx 5700 ultra has started acting weird lately… its showing 3 or 4 vertical lines made of “$” signs during the card bios , which later during loading windows turn into blue lines, when logged in card acts normally but nvidia drivers cannot detect it, it works as if it is without drivers, windows is able to show its name. games cannot be played on it , and i cannot shift to higher resolutions. i tried flashing the bios but it didnt work either. card is out of warranty aswell… lines are like this
$ $

have you tried it in a different machine? first thing i’d try is removing the heatsink and replacing the thermal grease possibly with some as5 if you’ve got any, you can also try installing rivatuner and underclocking it slightly, might work but just slower, but tbh it sounds like its bummed :frowning:
