Hi, my computer is infected with several Trojan viruses. Our Trend Micro PCillan antivirus protection was on, but somehow got through. I tried to "clean" and "delete" these but the buttons for this would not light up. My desktop had nothing on it and I couldn't click on anything. I turned the computer off (couldn't even shut down properly). When I restarted it the desktop kept flashing on and off and still couldn't click on anything. I turned the computer off again and this time hit the F10 button to do a system recovery. The system recovery went through fine, but when it tried to start the computer back up again I got a black screen. The keyboard and the mouse would not light up and they didn't work. My husband informed me this morning that there was a virus. He said last night some icons came up on the desktop and he had no idea where they came from. He also noticed that none of the icons for microsoft were on the desktop. (Ex: the my computer icon was gone). As of now I cannot get anything to come up on the screen to do anything. Just a black screen. I am currently using my laptop to access the internet to get on here. Please help and tell me what to do. Is my computer fried and need to buy a new one? My computer information is below. Thanks

Have you tried using Last Known Good Configuration or System Restore from a command prompt in Safe Mode to return to a previous state before your problems began?

Hi We just now tried both of your suggestions. It said that Windows file was missing or currupt and to install the Windows CD setup disk again. Should I try to install Windows XP again from the disk? The exact wording for this message is as follows: Windows could not start because the following file is missing or corrupt: WINDOWS\system32\config\SYSTEM: You can attempt to repair this file by starting Windows Setup wsing the orginal Setup CD-ROM. Select 'r' at the first screen to repair.

See How to recover from a corrupted registry that prevents Windows XP from starting and Registry troubleshooting steps.

There are many reasons why a registry hive may be corrupted. Most likely, the corruption is introduced when the computer is shut down, and you cannot track the cause because the computer is unloading processes and drivers during shutdown. Sometimes, it is difficult to find the cause of registry corruption....A power failure or some other unexpected shutdown event may cause a corrupted registry hive....
