Few altcoin wallets dont run (windows7) - before working ok

[Sjacmur]

I turn on my PC and last day my 3 wallets altcoins working but today not working.
I try start and nothing - my wallets not start
In windows menager I see it in "Proces" but not in "Aplications" and one wallet 3 times dont know why, other 2 times.
Other my altcoin wallets start run normal like usual but my 3 most important not start. Only windows small circle after try run *.exe wallet.
I restart my PC few times but not work.
I full remove one wallet and install from beggining but he start downloading blockchain but when I copy my backup file wallet.dat again not run.
And after unzip new wallet file I try start and dont start. But once I change name folder thi wallet it start one time but after I close dont start again. omg.
I no have idea what it is.

check debug.log and db.log files in your data directory. It may give you some clues.

db.log is empty in each wallet.
in debug log I not found important things.
