I'm suspecting my card is going bad on me. I lost one before where it just went sudden;y.

This time, what I'm getting, other thanan increased frequency of blue screens is the screen freezes completely, and a high pitched whine comes from the speakers.

Bad card? If maybe not, what should I look at to confirm?

If it's definately the card, I have a Nvidia GTX 280, happy with it and was pretty pricey when I bought it. Still considered a good card or there one better?

Thanks.
