Are you getting any error messages? Have you checked the event log to see if there are any errors listed there? Is this problem new and if so have you recently made any system modifications that may have precipitated this problem? Have you scanned for malware? Maybe use a restore point or a system image to get back to a point where you weren't having the problem.
Without any additional info such as Windows logs, stop messages, or hardware info; it can be downright impossible to diagnose the problem. Much more information is needed.
