Which parts, when defective, can damage other parts?

Hi all,

After an odd experience involving certain defective computer parts messing up other parts, I want to ask an overall question.

Is there any general rule about which defective parts can damage other clean parts? I know a bad motherboard can mess up RAM. But can it go the other way? Can a bad video card backwards-fry other components? Can a bad mobo screw with a hard drive? Other combinations?

Anybody who has experience on this matter (not just opinion), please let me know.

Yeah other than a PSU I couldn't see anything that would do that. Other than maybe if a fan doesn't work you could fry something. And maybe if your dvd drive is malfunctioning it could rocketfire a DVD into your mobo :)
 
The only thing that can damage other components as oscaryu says is the psu, if it fries it can take you whole computer or nothing, also fried cpu's can damage your motherboard cpu socket
 
Okay, basically I have a video card that's giving me strange display refreshes and pixel flickering. If I replace only the video card, will it be okay? Or do I need to worry about the video card having hurt the motherboard or something else?
 
It shouldn't, I put in a faulty card that would give me weird disply now and then, and eventually it just totally died. I just to kit out and everything was fine.
 
Unless the video card catches on fire, I seriously doubt it will hurt the motherboard. It is a fairly common occurrence for a video card to go bad. I have never heard of one taking out the motherboard.
