	If you are installing memory in previously unused slots, I've seen
this happen a lot. The pins in the MB slot have been plated with 8-9 years
worth of smog, crud and general corruption.

	What I do is dip the bottom edge of the memory module in 99%
isopropanol alcohol, and while wet, insert and remove it several times
This usually solves the problem. Oh and wait until the alcohol has
evaporated before powering up the system, dont want to explode...
