Windows XP Shutsdown on Logon Screen

Hi Experts;

I have a Windows XP Pro on my machine w/ 128 MB of memory running 2.0 GHZ AMD Athlon. The problem that I'm having
is that when ever I tried Logging in any account on my Logon Screen, what it will do is to shutdown and the only way I
could perfectly logon is do a standby 1st under the shutdown link on the logon screen. After doing a standby I will
resume it and thats the time it would let me logon to my desktop.

I'm an expert at this so what I did was to clean my msconfig start-up variables and turned off my system restore. My brother
said that our antivirus found a virus so he tried to delete it, now when I tried to update my virus definition and scanned
again and it found nothing, I also tried disabling the logon screen but did not work. So I tried to change the logon screen
using another lognui but no go.

So I'm begging any one there do you know any virus who can do such a thing ? Or do you know any quick fix to this
because I dont want to reinstall windows again.

Thanks To Everyone !

Hi;

Thanks for your comments but I'm an expert at what you said.

> Click Start, point to All Programs, point to Accessories, point to System Tools, and then click System Restore.

Did you read my question I've turned off my System Restore !

> How Do I Do a "Repair Installation"?

I already know that like chkdsk /r under recovery console or repair install ? What I wanna have is a quick fix
under the registry or anything that can fix the problem easily.

Why do people turn off system restore makes no sense to me. Sense you are the expert here what do you think needs to be done. If you are such an expert than why don't you know to about REPAIR. Sorry but any expert in XP knows about Repair and will know how to use i8t so please explain to me why you think you are an expert in XP. Otherwise read the links I posted.

And what do you propose to do with the registry if one can't boot into the OS. Yes you can grap certain registry hives throug by loading a hive but only if you have another XP OS to load the hive to. And what do suppose is the registry setting that needs to be change. The easiest fix right now is probably the repair installation. Anything else would be more time cosuming and more likely to mess things up more. Do the repair and be done with it.

Because doing a system restore can bring the virus back to life thats why any antivirus
company suggest's that.

> why you think you are an expert in XP

Because I know already what you suggested. I'm using a computer for so long since widows 98
I'm a programmer and I know alot of hardware and software problems.

> Sorry but any expert in XP knows about Repair and will know how to use

The cd of my windows xp is not w/ me that's why I want to know the name of the virus and the
quick fix to it w/o repairing or reinstalling windows.

Well my brother said that a virus just infected the computer and he deleted it w/o getting the name of it and the
other thing is that I already checked on the programs w/c are installed on the computer but there are no malicious
programs there besides from my software's that I use for programming.

If it is a virus then I am very doubtful that it is just a registry problem. It probably also includes some system file changes hence doing a repair would be the way to go.

You could be right about that because I just tried helping my neighbor about their virus problem
and I found out that the virus that they had leave a vbscript file on their machine and I tried
deleting that and it works.

How I wish I could just do that on my freaking computer.

I left it on my mom's house that's why I cant do a repair on repair console now.

Ok I now understand forgive me for my outburst I was out of line. :)

Although using that CD is probably you best chance. Do you have any ideas what registry settings you think may make difference? And can you boot into safe mode if you can do a


start > run sfc /scannow.
