I found this at the bottom of my PC case. First of all, I just thought it was a spacer or something like that.Then I realized it is actually a component. How come My PC is still working?????http://forums.avsim.net/user_files/186991.jpg

I haven't seen one of those fall off before - looks like a surface mount resistor or capacitor. Most of these are essential, but others are just there for good measure in the name of overall system stability. Looks like you are lucky enough to be in the latter camp (otherwise your computer would be dead right now!). I suggest you run a hardware testing program, like prime95, for a few hours and see how she holds up. Heck, if it can run FSX for a couple of hours it is probably just as good a test as prime95 as far as you are concerned.The other possibility is that it fell off your video, or another add-in, card. Getting any strange graphics behaviour?Gary

I haven't noticed any odd or strange behaviour above the usual - baring in mind that i'm running an overclocked system that is.I did a major upgrade a few months ago, and sold on the old bits on eBay. If it was from an old item, i guess it's not surfaced yet.
