I am looking to replace an ATX motherboard thats about two years old, its a Intel Desktop Board D925XECV2 LGA775 Socket. It has constantly been overheating. It sits in a Silverstone LC10M case. I have used my HTPC sporadically, though get fed up with constant overheating regardless of what i've done, it appears these boards are particularly suseptable to this. I recently found XBMC so have a revived interest. I want to maximise quality so thought I would go the HDMI route given I have a decent AV amp with switching. I therefore now want to replace this failing motherboard but retaining all other components inc DDR2 Ram and P4 3.2 chip. Can anyone therefore recommend a straight replacement. Also can you advise if replacing the motherboard requires reinstallation of the OS, I am guessing it does, if so is XP still a reasonable choice? I am a newbie as such so appreciate any advice.
