i'm trying to install a Winfast DTV2000DS twin-tuner TV card. the first time i tried i got this BSOD......... so i took the card back to the shop, told them what happened, they put card into a brand new system and card installed perfectly within 5 minutes. i bought the card home and checked for any possible conflicting drivers, found some pinnacle ones that i uninstalled. i tried again to install the card and got the same results as before. can someone please tell what to do to fix this problem. my system...... Win7 Ultimate Corei5 4gb DDR3 1333 ram nVidia GTX260 Thermaltake 700 power supply Samsung 23 inch LCD cheers, fingers crossed.
