Unable to boot XP while Safe mode gives blue screen with question mark

I am unable to boot my windows XP from the last night also when i try to boot with the safe mode it just gives a blue screen with a question mark. When i boot normally it hangs on the logo screen. My system was infected with a Trojan horse. Please help me solve this problem i would really appreciate your help.

It is mainly due to the corruption of the system files and hence you need to repair the system files using the recovery cd which you have got along the Desktop at the time you have purchased it. Follow the step by step instruction to repair and You can now boot in to your system as soon as the repair gets completed.

I will suggest you to perform the following steps which i have mentioned below in order to get rid of this error.

• Put the Recovery CD within the cd drive and restart the computer.
• Now you will see a blue screen with message Welcome to Setup click R from the key board
• If prompted then press the Enter key and the repair will start.
• The system will start automatically as soon as the repair finishes.

Try to repair the windows XP if possible with the help of the windows XP Discs. If you cannot do the repair then you have the last choice to reinstall the system once again. After installing windows XP again try to make your system more secure using some antivirus application i recommend you the Avg Antivirus professional build

This is a very critical issue since it appears as the Trojan horse which you had on your system might have corrupted the system very badly and hence the system is not booting so i think you should wait for about half an hour and then restart your system again then try to boot with the help of safe mode the system may boot this time.
