if you have the windows xp disk, boot from it by pressing F12 upon turning on your computer. press 'R' to choose recovery console. you might be asked which windows installation you want to start, just press 1. when you see the console, enter the command 'fixboot' without the quotes. then type exit to restart your computer. hope it helps.

Boot your computer to safe mode and change the display settings to either 800x600 then save and reboot once it comes back up you can change the display setting to what you prefer.
To get into safe mode press F8 on you keyboard every second while it is first booting up.

You have a virus most likely. You will need to boot with an antivirus cd & let it scan & repair the virus damage. After this is done you should have control of your system again. Hope this helps.

Reboot the computer. Press and hold the f8 button. Select safe mode from the menu. You should be able to see the admin login. Then you can make the changes.

One of these; Esc & F10, will give you access to the BIOS settings that are stored in a bit of memory (CMOS) that the system reads at turn-on.
You will get a text-only screen with a number of function selections which can vary widely so look at them all without making any changes (arrow keys and Enter selects) to see if the feature that is causing you to choose at every boot is a BIOS setting.
All BIOS seem to offer a 'Save and exit' or a 'Exit without saving changes' type of choice so if you find none that logically could be altered to avoid going through those menus each time, you can return to your undesired condition without messing up anything.
Also typically present in BIOS is a choice that read something like 'Return to factory defaults' which will automatically change the setup to something safe and that which most users want. If you choose that one, then you need to choose the 'Save and exit' selection.
The reason for those steps is to allow those who use a Unix-based (or other) alternative operating system for some tasks to choose different boot modes.   

Hi.

Even i once had this problem.
There are two solution.
First remove the ram and wipe it then fit it again.
If this doesn't help then get the system formatted.

Hope this will help you (By the way it did helped me)
