Fried VIA KT600 (Northbridge) - VIA 8237 (Southbridge) mobo.
Alternative replacement available using VIA KT600 (Northbridge) - VIA 8235 (Southbridge) mobo.
Same manufacturer, same model - seems to be slightly different mobo version.
Question: Will system be able to pick up and run without Windows reinstall or something similar?
Last time I had to replace with different manufacturer and model VIA board. Windows was a little distrought and I ended up being forced to reinstall it from scratch.
It shouldn't cause any porblems but to be safe i would google a utility called sysprep which is on the win xp pro cd that wipes system info and allows to to move windows to a different computer without requiring a reload.
