media center locking up & wondering if it's because of my video card
Three times yesterday my computer apparently locked up while I was watching recorded high-definition programs in Windows Media Center. Two of these times the screen simply went blank and I got the no signal detected message on my monitor. I have no idea what was going on with my computer at that point since I could not see anything (couldn't hear anything either because the audio was coming out of my HDTV which I was using to watch the programs via a DVI/HDMI connection). The other time this happened, it simply froze the screen and the whole computer was unresponsive. All three times I had to turn off the computer and turn it back on; I couldn't get it to reboot any other way. These lockups occurred after about 30 minutes of TV watching and were accompanied by one of my fans revving up real high. I'm wondering if the cause is from my video card overheating which could explain the loss of the video signal and maybe the reason for the fan spinning so fast. Today I would stop my TV programs after about 30 minutes and wait five minutes before resuming and I had no lockups. Does this sound like the video card or something else?
