Assume current wallet, synched and unlocked (if encryted) - If all of these are OK then,
How many coin input blocks do you have?
How many coins per block?
What is your oldest coin block and how many coins in that block?
If unsure check coin control.
If coin control not set up go to: Settings/Options/Display and check the box for Coin Control
Then, go to Send Coins tab and click on Inputs button at the top. Then, dble click on coin total -
a list of your coin blocks will show.
