when i turn on computor i am admin and it keeps saying service log in failed ,?

your comuter probally locked or crashed.

Also do you have anti virus and male ware protection and firewall activated. If you do not activate fire wall first. And use system restore after down loading and installing anti virus and male ware programs scanning and updating.

Firewall, That option comes up after service pack 2 (sp2) down loaded & installed in your computer.

All are good but a lot of people do not update after they get them.

And it only takes a couple of minutes.

Make sure you update everday they are not automatic

Get an anti virus progam also male ware program and use scans on both.

Pick they are free. But only 1 anti virus and 2 male ware programs!!!!!!!.

Download these free scanners from these websites:

Spybot - Search and Destroy: http://www.safer-networking.org/

Spybot - Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications. Spyware silently tracks your surfing behaviour to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies. If you see new toolbars in your Internet Explorer that you haven't intentionally installed, if your browser crashes inexplicably, or if your home page has been "hijacked" (or changed without your knowledge), your computer is most probably infected with spyware. Even if you don't see the symptoms, your computer may be infected, because more and more spyware is emerging. Spybot-S&D is free, so there's no harm giving it a try to see if something has invaded your computer.
