I'm not sure whether this is the right forum or not, but I'll give it a try anyway.

My sons computer has been suffering some strange freezes while the computer is running. He's got Norton Systemworks installed and has run through everything on the list in an attempt to figure out what's wrong. I watched him do most of the tests without incident.

He'll be just surfing or downloading songs or some such thing when all of a sudden nothing. The screen is still up and we can see everything clearly, except that it's frozen. Can't do a damn thing. Mouse doesn't work, ctrl/alt/delet doesn't work. All that remains as an option is to shut the powerbar off. Turn the unit back on and it's working fine, but for how long is unsure.

The only thing that I can think of that might be an issue is the video card that he's using. After he'd had the card for a while, the cooling fan on the card started to hum and make some very un-natural noises. A little oil under the sticker fixed that right up. But it got me to wondering.

What if the fan has stopped working and now the video chip is over heating. Would this be enough to cause the computer to freeze?

If anyone has any ideas, please feel free to post them.
Thanks.

My first thought is CPU overheating. Take the case off and see if the fan is moving. If it is, put your vacuum cleaner on blow and blow the heat sink out. If it isn't moving, replace the fan! That is where to start, please keep us updated.

Well, it's not the CPU fan. It's running fine, although a little dusty. The video card cooling fan is another story. It was stopped cold. I pulled the card and removed the fan and cleaned it. I actually managed to get the little bugger apart without breaking it, and gave it a good cleaning and a little drop of lightweight sewing machine oil. Hums along now as if it's new. Gave the inside of the tower a quick suck(my vacumm doesn't blow, just sucks....lol:D) to get as much dust as I could. So far, so good. I left the computer running over night to see if it would freeze up again, but it seems to be working fine for now.

If I get a re-occurance of this problem, you can count on my coming back here for more help. Thanks guys(and girls).

One question. Would a siezed fan on a video card cause the computer to freeze in this way?
