That seems unlikely. I am guessing you are talking SQL to your database, so either it receives the SQL and executes or it does not.
You haven't really given enough information to really diagnose an issue. If I had to guess, I'd say it's something bad in the software its self. Maybe some sort of table lock timing out but even then corruption seems unlikely.
Is the database on a seperate disk than the operating system? Is it possible that disk controller is gone or going and writing bad data?
