Fatal Error c000021a 0xc0000135

This is Windows XP Home SP2 computer. I started this computer after three days of using it last time. On the first boot today I received a fatal error saying “Fatal Error c000021a 0xc0000135.” I don’t know how it came because nobody used it during this period.

Any idea how can fix this problem?

This error can occur when you have GoBack installed on your computer and it is present in the boot sector. In order to fix it, just follow the steps provided here: http://support.microsoft.com/?kbid=316503

Thanks for your help Lyalisai but I don’t have GoBack installed on my computer. Anyway, I tried booting my system in Safe Mode as well but dint found any problem. Even my command prompt is not opening. I tried few more suggestions and symptoms on web and it seems like my video card is faulty itself. I’ll try removing it physically and check if the problem goes away.
