The browser service of a Microsoft Windows computer in a WORKGROUP can cause a failed logon attempts in the Security Log in Event Viewer. Fortunately this is easy to test.
Test:
1.) Disable the Browser Service on the computer where the failed logon attempt originates from.
2.) Reboot that computer and log on.
3.) Watch the logs on the computer with the failed logon attempts in the security log of event viewer.
Test Results:
1.) If there are no failed logon attempts then the failed attempt is a harmless browser service sweep of the local subnet.
2.) If there are further attempts suspect malicious software and continue to search for the cause.

I have an old HP Pavilion w/XP. I turn it off and electric strip off every weekend because I go away. No problem for couple years doing that. I turned it off for two weeks when I went to Costa Rica and when I came back it won't work. I turn it on and it starts to boot up and even gets to where I login, but it seems within a certain period of time the screen shuts down and the indicator light on the computer isn't on but I hear sound from the hard drive. Got any suggestions?
Being that it is an older computer and you have left it offline for a two week period, I would recommend a few things. Usually when a machine powers on but dies over a short time, heat is the culprit. Power on the computer and make sure the fan in the power supply is spinning...you should be able to see this from the back of the tower. You should also take the computer outside, open it up, and use a can of compressed air to blow out all of the dust and such that are inside. Short of that, if heat is not the issue, it is either a motherboard that is on the fritz or a power supply that is. Often, we relate two coincidental things (such as a two week hiatus of the PC and the current set of problems), when in fact the machine just reached it's limit. Those are the easy things to try. If it isn't something simple, I would consider purchasing a new PC rather than taking it in for repair. Often, the diagnostic alone will cost 50 or more dollars with the repair usually over 100. For a few hundred more you can get a nice new PC.
Wendy,
You may want to try and boot to safemode (press F8 during the windows boot process). If that doesn't work then look at the heat issue/hardware issues that Ernest suggests. If that boots and you log in successfully then try a system restore. Failing that you would want to start uninstalling and reinstalling drivers, checkdisk, defrag, the normal slew of basic troubleshooting.
