Could really use some helpful info

I have been through about 3 360's so far. my last 2 ended up with all sorts of problems and i ended up getting those red lights of death I dont know what their called but I never had any problems until I had set up an Xbox live account and had gotten updates and through all sorts of random crap with my computer and moving I am setting up my xbox live again

And to make a long story short I am wondering whether or not getting the updates are gonna cause me to have my 360 die again because I had read in some places certain updates would cause the 360 to have compatibility issues and then more or less die.

System updates don't happen very frequently (3-4 per year) and if they go wrong they make some pattern of red lights on the front (not the RROD, but another pattern using only some of the quadrants). If this happens then MS have a way to reset the console back to its previous state, but you would have to either Google it, or call MS when it happens.

System updates are very unlikely to fail, unless you have a powercut or lose connection to the internet while it is downloading and updating.
