Why my PC reboots frequently and suddenly?

[cubus]

My computer reboots frequently, suddenly, unexpectedly, even if I not work
on computer at the present moment. What can be the reason? Is this PC Power
supply problem? Or room power supply?

I looked at event system logs(eventvwr.exe), there are 2 main errors
repeated: Event ID: 17 and 29.

Is there some connection with PC rebooting or not? If so, how I can correct
problem?


thank you.

Hi,
"User Action"
"Do one or more of the following":

a.. Verify that the DNS name for the time source is a valid
ame. -How? What is 'DNS' name?
b.. Verify that the time source is available on the network by
pinging the server. - How?
c.. Confirm that Windows Time Service (or other NTP Time Service) is
running and available on the source system. -HOW? Its easy to say for
microsoft, but for home user it's a problem.

Hi

Go to Control Panel>Date and Time, then click on the 'Internet Time' tab.
Which Server is showing? If the drop down menu shows another option, try
that one.

There are time.windows.com and time.nist.gov. Time.windows.com is default.
Is the Event ID: 29 'W32Time', and Event ID:17 'W32Time' the reasons that
computer reboots? Or rebooting caused by other reasons? My problem is
rebooting, I want know exact reason of that problem.

Thanks
