I just thought to share my new experience with a fine working mobo that started diying on me slowly to the point that last night it wouldn't boot any longer. I am a PC technician, so i started with all the usual measurings and isolation tests. CMOS clear, PSU was fine, memory was sitting perfectly, everything looked fine. When i reached the VGA isolation test i found out that as soon as i removed the VGA the system would boot. (You can hear the POST beep and see the lights go on at the right sequence, while the fans go down after the full on POST). So i checked the VGA for anything that could seem damaged (see leaked caps or anything). But nothing at first sight. My graphics card is a GeCube Radeon X850 Pro with the stock cooler on. On closer inspection i found something that was quite disturbing. Right under the fan on the GPU, a part of the GPU is exposed (not the core obviously!) but it's those small resistors that sit on the GPU. And they were all covered in a thick layer of dust! I have seen lots of shorts due to dust in PC's before, so i knew that was bad! Trusty screwdriver in hand, and off the heatsink of the GPU went. I cleaned the chip thoroughly (even got the chance to remove ATI's crude thermal paste -a ton of it on the chip!- and put some artic silver on.) Well, not only as soon as i replaced the VGA on the mobo, it booted instantly, the temps have dropped a futher 3oC at idle and 4-5oC at full load! Woohoo! And lucky my card didn't short to the point of death!
Therefore users of a GeCube Radeon card with the stock cooler on, have in mind the dust accumulation in case your PC starts behaving erraticaly and you can't find the reason. One more thing on the checklist!
