check which processes are taking max resources..

It means that the OS is not good, it could be "infected" in some way. The processes at the application level can hang it only of they grab very high priority. I hope you don't do it. Some problem can be caused by defective kernel-mode drivers. Everything else can rather be classified as "viruses"...

Now, how do you know that hanging is related to this application?

How do you know? Say, if some process grab very high (read-only) priority permanently, the OS will hang. See also my comments to the question for some other reasons.
