Check to see if your video card and monitor are functioning properly.
Make sure you have the latest video drivers also.

Answer 2

Installing the Windows XP Recovery Console
Windows XP won't even boot up, even if you use the Last Known Good option!
There's one thing you can do before giving up, and that's to use the Recovery Console.
The Recovery Console gives you access to a DOS like environment where you can try to fix things you suspect are wrong.
You should definitely install the Recovery Console if you're a power user. Just do the following:


Put your Windows XP CD into the CD-ROM drive.

Click Start, and then click the Run command.

In the Open text box, type

d:\i386\winnt32.e x e /cmdcons


Change the drive letter to your CD drive if D: is not your CD drive letter (don't type spaces in the filename).
In the Windows Setup dialog box you'll see a description of the Recovery Console. Read it and then click Yes to install.
Restart the computer. The next time you start your computer, you will see a "Microsoft Windows Recovery Console" entry on the boot menu.

Answer 3

Call customer support for your computer, and see if there is anything they can do. They can tell you what you need to do. If you don't remember or your warranty's expired, call a local computer repair, such as Geek Squad or a more local company.

Answer 4

The master boot record (MBR), partition tables, boot sector, or NTLDR file is corrupted.
