Hi, i had my system built about 2 months ago and all was fine. But since installing my win tv express card, sometimes watching tv on the monitor it freezes up and just the sound is there and i can do nothing but restart. It may not be the tv card, but can anyone else tell me what it could be. My system specs are, amd athlon xp barton 2800 processor, MSI kt4av mobo, 256 ddr ram, radeon 9200 256 ddr tv dvi out gfx card, 2 dvd drives, and a maxtor 80 gig harddrive. Thanks in advance.
