I cannot remember anything exactly like you have now, but weird things happen. Have you tried the very basic; plug out every cord, disassemble the battery and have a cup of tea, then assemble all again, and boot up?
Failing that, you could burn a Linux live CD like Puppy Linux or Ubuntu, and if computer boots up fine then it might be something with your OS or hard disk.
Come to think of it, when harddisk fail majorly you can get something like you have now, but that usually comes with a lot of ongoing trouble the last few weeks or months.
