Last weekend i picked up this card at a yard sale for about $25 with the purpose of using it in secondary PC. After installing the card and its drivers , and uninstalling my old 550ti card and its drivers. I found out that this card crashes 10 or so minutes- this happens if leave my pc idle or if Im playing a game , my screen freezes and i have to power on/off my pc to get it started again. Also when I try to install the cards drivers my pc freezes during the installation.

The Specs of my 2nd rig are :
CPU: i5 2500k
Ram: 8gb
PSU: corsair cx 750m

This isnt really a priority but i would like to know if there is any possibility of getting this card running properly .
P.S when i brought the card the guy said that i would occasionally crash, however i thought it would be cool to benchmark this card with newer games.
