Answer 1

If it could not load Windows, the OS could be messed up. Try this repair that leaves all files intact:

Answer 2

First Step:

Update your windows files because an unprotected, unpatched Windows XP installation will get infected within minutes of connecting to the Internet.
Now install a ccleaner on your pc (you can download it form http://www.ccleaner.com):
1. Before first use, check under Options, Advanced, and UNCHECK "Only delete files in Windows Temp folder older than 48 hours".
2. A pop up box will appear advising this process will permanently delete files from your system.
3. Then select the items you wish to clean up.
In the Windows Tab:
Clean all entries in the "Internet Explorer". Deleting cookies will require re-entry of user names and passwords on next visit to sites that require users log in.
Clean all the entries in the "Windows Explorer" section.
Clean all entries in the "System" section.
Clean all entries in the "Advanced" section.
Clean any others that you choose.
In the Applications Tab:
Clean all (optionally, except cookies) in the Firefox/Mozilla section if you use it.
Clean all in the Opera section if you use it.
Clean Sun Java in the Internet Section.
Clean any others that you choose.
4. Then click the "Run Cleaner" button and it will scan and clean your system. Click exit.

Step Two: Viruses/Trojans

Hi I had this same problem with my old Siemens. I turned it on it reached the dos part and then a blue screen sometimes appeared and it turned off. I though that the problem with my computer was that it was overheating. So if yours is quite old try removing the case and turning it on, then it wont overheat. If this isnt the problem it could be the RAM, give it a clean or install more, memory is crucial to the start up and maybe you dont have enough to run your O/S. If its none of these problems then try and reboot your computer. Press F8 while it is starting up and press reboot. If this doesnt work a last resort would be to reinstall your o/s, which could make you loose all your files. Hope this helps. Kieran
