I am not able to find any specific on these Event IDs in Microsoft Knowledge Base. Can anyone tell me how to solve this problem?

The problem that you are facing can occur because of an issue in the Volsnap.sys file. This issue generates a deadlock condition. In the deadlock condition, the system I/O is suspended. A file deletion operation is waiting for the system I/O to resume. So, to solve this issue, you can follow the suggestions given on this website - http://support.microsoft.com/?id=923628
