hey all, i was looking at getting a tv for my room but then got given a 22" LCD monitor for my bday for my computer, seeing as that was bigger then tv i was gonna buy for my room i thort i mite use that for TV instead of wastin space and money on another tv. I already have a tv tuner card in my computer, ive had it for ages. The thing is thou when i got it, it worked, but only for about 10 seconds, sometimes for up to two minutes before the computewr would freeze, when i bought it i paid about 200 bucks for it and it wont even play for more then 2 mins without freezing, now i have this screen i wanna get it workin.

can anyone tell me why my computer freezes??
