unexpected crash

Hello Experts,
Some of our stations have started to crash.
All of a sudden they freezae and we need to restart them.
When restarting they say windows recovery and last almost 30 min to recover automatically.
 
Our apps are stable everywhere and there is little installed in each computer.

Cant explain why this is happening.

Is there any tool or procedure you can suggest me to check the integrity and how stable that station is ?
Those particular stations were using win 7
Regards,

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
