Daily rebooting of computer

[Dave]

For quite some time now, my computer has been rebooting
on its own at random. I have had this problem for quite
some time now and I have been unable to fix the problem
myself. It seems to be related to the Internet, and will
happen while I am doing work online. I have my security
up, and I have anti-virus check every day for any
indication of this problem but with no avail. If someone
could suggest any thing that might turn back this problem
of my rebooting computer, I would be extremely
appreciative.

What you have not said is that you use automatic updates
from Windows Update and every critial update is installed.
There are some exploits out there that can cause what you
describe - system shutdowns / reboots but no infection.

Yes, that is true, I do have Windows automatic update.

But if there are exploits, what can I do to stop them?

Automatic Updates - can and has in the past - rebooted without informing the
user it is about to if you have it setup to download and INSTALL the
updates. It is better if you just set it to download them and notify you -
then you install them.

If you today manually were to visit Windows Update
and it finds no needed critical updates, then the next
step may be to look to malware resident on your system
(using a tool like adaware or pest patrol and a couple
anti-virus scans).

This can also happen from hardware issues.
In the System properties (r-click My Computer) locate
in the startup environment the checkbox to automatically
restart of stop/failure events and shut this off.
Then you may collect info the next time this happens (you
have not really indicated the exact sequence of events when
it restarts : it just does it with no warning, or, it pops up a
message that . . . then restarts, etc.)

Well, I thought I explained it quite well but I see your

point, it specifically happens when I am on the Internet,
lets say I am going to a site, the computer will just
reboot itself, no warning, no shutdown, just an automatic
restarting of itself.

You still have not stated that Windows Update sees
no needed critical updates.
One can have automatic updates turned on but not
be up-to-date if you have ignored a notification.

If you are having problems being up that long, turn on
the built-in firewall first then manually visit Windows
Update.
As said in initial post, there are things loose on the
net that will bring down an unpatched system.
Thus we must rule out lack of service as the cause.
