theres no problem im not sure why but it will do that my 160 gig only shows up as 149
the reason your 160g hdd shows up as 149g is because hdd manufactuers use 1000mb's to measure a full gigabyte, while windows uses the more correct 1024.. so in actuality you only have a 149gb hard drive.. works the same way for everyone else.
Hanzu has a different problem.. one i'm going to try to figure out.
edit: make sure all the ram you have installed is compatible with your motherboard.. you can do this by reviewing your motherboard manual, or googling your motherboard model.
double edit doh': i wasn't paying attention to your specs, forgive me
Does windows even reconize more than 2gb?
