Site-use tip
suggest-- when you repost-- go into "User CP" "edit options" --scroll down the list.
List all your hardware in the spaces be sure to list the Brands and Model Numbers
-- at the top-- there is an option to "allow others to view my specs"-- click on yes.
It saves a lot of time between posts if while you check something I can go look up your motherboard manufacturer's site and read the manual.
You can also list your OS...all this is a great time-saver for us-- we can view everything quickly to refresh our memories... as we are all working multiple threads at once.
This would be automatic from that point on-- so if you have another problem six months from now-- we can instantly know what you have.
