I currently had Office 2003 on my PC and wanted to upgrade to Office 2010. I inserted another RAM card and it blew the motherboard. Why would this happen?
Note the RAM card was slightly smaller in height but had the same insertion slit points.
Would any of the other components of the motherboard be working now?

Quite possibly the RAM module wasn't compatible. Did you check that it satisfied your M/B specs? As for whether anything else might work, you'd have to test each component.
