Desktop computer starts up, black screen with data runs, black screen with Windows XP logo and green progress bar runs then when it would normally go to the blue welcome/login screen I get this message message box on a black screen:-
"lsass.exe - Unable to locate component
This application failed to start because WLDAP32.dll was not found. Re-installing the application may fix this problem."
If I click the "ok" in the box or the red x it goes and am left with a totally black screen.
If it is a virus I am frightened to do anything which may make matters worse
Any advice would be greatly appreciated.

Can you boot into Safe Mode and use System Restore to roll back a couple of days?
Do you have an XP CD, as you may need to boot from it to access the recovery console?
There are some general suggestions here. You may be able to get away with just needing to copy the WLDAP32.dll file back into the C:\windows\system32 folder. There may be a copy of it in the C:\windows\system32\dllcache folder which you can use.
And if the XP loading bar is green instead of blue, it means you're running XP with Service Pack 1 or less. You really should be on SP3 now, so if you do manage to get it working again, you should update ASAP.
Plus, a Malwarebytes and AV scan should be run as a matter of course.
Sorry, the loading bar is blue, was thinking of the wrong loading bar. I think I am on SP3 as the PC had SP2 when we got it and have always had automatic updates.
Tried that and get the same black screen with message as before.
Not sure how to do that when I can't get past the black screen but will investigate that link you posted and see if I can find something to help. My computer knowledge is quite basic so thanks for your advice!:)
Went through several attempts to sort the problem but was still unable to get beyond the black screen so tried re-booting from the original Windows XP CD, still no success and it wouldn't let me into the recovery system. I tried a re-install of Windows and thought it worked okay. It took me back to XP service pack one so I started to work on the updates to get it back to SP3. It seemed to update okay and looked like it was back to normal when I opened it up this morning. Went to install the last of the updates and while it was checking the system I got a blue screen with a stop error. It said somehting about "memory management" and "file dump". Before I had the chance to read and take in all the info it was showing the machine shut down. When it opened up again it won't allow me to login to windows and keeps asking for a password. I have tried what I thought the password was but it keeps telling me that it doesn't match the user name/domain and I am still locked out. If I leave the password blank and click okay it goes to the desktop backround screen with no icons at all. Just the picture and cursor?

What's the make and model of the machine? You may have a hidden recovery partition on the hard drive which will allow you to restore everything to factory settings instead of using the XP disk.
It must have been a repair install as when it was finished everything seemed to be there as normal, I didn't have to log in or anything, my normal welcome page was there with my name, all the desktop icons were there and checked my email in the morning with no problems. It seems to be back to SP2 level looking at the info on the black screen. It seemed to be okay until I tried to update with SP3, that's when the latest password login problem started.
It's not "big brand" machine as I got it from a local computer shop (Sept 2004) but here are some details of the build, these may help.
Processor - AMD Athlon 3000XP
Motherboard - GIGABYTE GA7N400 PRO2
Memory - 512 DDR400
Hard Drive - 160GB 7200 RPM 8MB
The system was backed up a month ago so would only loose stuff from the past month BUT my son has been working on several job applications and was hoping not to have to wipe the system as these are not on the backup drive.
The computer went to a repair shop about 18 months ago and they wiped the whole system and reinstalled windows then with the original disc. Could they have set the password that I can't seem to get past? As I recall the machine was ready to use and I just had to reinstall all the programs we wanted to use.
Thanks again for your advice and I hope my ramblings make sense!:)
When I switched on the PC this morning once the bios data on the black screen was loaded up it switched to a light blue Windows XP screen with white text performing a DSKCHK. I have seen this before but this time it was different. It started to show details of hundreds of files very quickly scrolling down them all until it said the usual stuff. The scrolling text said something about "sorting errors in index $130 for files *****"(with loads of numbers of files.) It also said a similar thing about "orphan files". It completed this disc check and then returned to the black screen with windowsxp dialogue box asking for the password. I still can't log in to windows and keep trying lots of passwords that I normally use but still nothing.
Once Windows is installed, you'll need to install all the necessary drivers and whatever additional software you use. XP will also need to be fully updated and AV software installed. It can be a long job if you're unfamiliar with it.

Thanks in advance once again:)
Ensure the Windows Firewall is on, connect to the internet, download, install and update your AV.
Install all XP updates. You can leave Automatic Updates do it all for you, but it might take a few hours.
Once XP is fully up-to-date, start putting your software/hardware back on. Install them one at a time instead of all together, so if anything goes wrong, you can figure out what caused it.
Insert the disk/USB drive with your data on and run a virus scan on it. Once complete, copy all your data back.
You can run a program like Recuva to try and recover your old data, but this should be done right at the start before installing any other software.

oops, sorry annie, keep forgetting about your site
I'll let you off this time, don't do it again
Naughty, getting on the wrong side of Annie.
Hope you can swim when you fall through that ice.
Thnks so much for that, it will take me a while but hopefully I will get it sorted! Now all I have to do is find the correct driver discs in a big bundle!!
Cheers
