Here I had tried to use a screen saver and after that there is a blue screen error on the screen. I am getting a constant blue screen message which is STOP: c000021a. I am also gettinga new error logon failed at 0xc0000135 when I try to login .What should I do here to fix the issue.

I will also recommend you to format your system once again to gain a bit more stability. Bluescreen is a serious error which is caused by damaged system files or hardware. It is essential that you must check properly which recently installed application is causing the problem. You can also try to disconnect your system from internet and then test back. There are some applications that work on lan level. The issue can be due to that. Just remove those things and then check back.

I have fixed the problem. Follow the steps below.
1. Go to safe mode by pressing F8 when booting up
2. In safe mode, click stark>run and type in msconfig and hit enter
3. Under general tab select Diagnostic Startup and hit apply and restart your computer in normal mode
4. After restarting your computer, if internet is working, do windows update and install SP3
5. After restarting your computer, if internet doesn't work, go to msconfig and under services, enable only the obvious microsoft services and restart
6. Once done with SP3 install, your computer should be good to go.
I did the above steps and it works on my computer.

Boot into the Windows XP Recovery Console using the Windows XP CD-ROM or using the startup option (if available). See article How to install and use the Recovery Console in Windows XP for more information. Type in the password for your installation of Windows XP, and press Enter. When you see the C:\Windows Prompt, type this command:DIR $*. This lists all the folder starting with the letter $. All the $NtUninstall.... folders are now displayed. $NtUninstall folders are nothing but the Hotfix backup folders, which contains the original version of the system files, before the hotfix was installed. Note down the Hotfix numbers matching the date you installed the problematic Hotfix(es). Spot the Hotfix that you want to remove, and change to that directory by typing this: CHDIR $NtUninstallKBnnnnnn$\spuninst. Once you're in that folder, you'll need to execute the spuninst.txt which contains DOS commands, similar to a .BAT file. The command instructions in this spuninst.txt file will actually copy the original system files to their respective folders. To run the spuninst.txt file, type this: BATCH spuninst.txt.

There may be some of the files in your operating system that are corrupted, and that is causing the issue like this. If you are not able to resolve this then the only option that can solve this problem is reinstalling the operating system. But make sure that you have tried all the other things for this and this is your last option. Good Luck!!!
