Windows XP Pro sp3
Boots to welcome screen with user name but selecting that opens with just desktop picture, no icons or taskbar. Starting explorer.exe from taskmanager briefly displays task bar but explorer crashes. Windows Live OneCare did find and quarantine a backdoor but I stupidly did not write down the name. I installed AVG free and ran it but nothing important. I have also run Malwarebyte, Spybot Search and Destroy and SuperAntiSpyware. All found cookies but nothing major.

/WINDOWS/explorer.exe is 1,010 KB dated 13/04/2008 7:12 PM

Have you seen this before?
Any Ideas

Does it exhibit the same behavior in safe mode?

Pretty much. It offers Administrator or Beth, It does bring up the Safe mode screen in either, a quick flash that is not readable but I suspect is the taskbar, and then a black screen with Safe Mode Microsoft ...(Build 2600.xpsp_sp3_gdr.100216-1514 ...

Taskmanager still comes up with Ctl-Alt-Del. In Administrator there are only 14 processes including System Idle Process, taskmgr.exe, avgcsrvx.exe (3 times), svhost (2 times)lsass.exe, winlogin.exe, csrss.exe, smss.exe and System. Only taskmfr and idle have significant CPU.

Looking around, there are no files in the system folder. The date modified is 15/05/2008 but of course that might not be correct.

Just got smart enough to realize I should run chkdsk /r is what I need it there are damaged sectors. It has replaced bad clusters in |WINDOWS\system32\drivers\rasacd.sys and \WINDOWS\win.ini. I will let if finish and see how it goes now.

If that doesn't work and you have your original install disk, run "sfc /scannow" from the command prompt.

I have her machine back up there does still seem to be some damage. It is a Lenovo and on boot it complains about an error in the security system. It will boot and the desktop is functioning now. I will have a further look when time permits.

What I did was to boot into the recovery partion to see if there was some way to run sfc from there. They have a report that shows changes in the last week. There was an Intel network monitoring program and a couple of others that did not seem essential. Google desktop had also been installed (or partly). I removed the Google desktop from Add/Change programs in the regular boot and Explorer now runs.

Still some cleanup but nearly there.

Thanks for your help
Gord

I'm sorry - missed it in your earlier post - you have bad sectors? If there are actual physical bad sectors and not just file system corruption, it could be early signs of a failing hard drive.

Maybe you should run the appropriate hard drive diagnostic, just to be safe:
