Solve the problem that the computer optical drive "jam" causes the black screen not to enter the system

One day I turned on the computer, but the computer read a disk after a black screen, but did not crash, soft start is invalid, had to shut down the machine to open again, but the fault is still. Back into Safe mode, but the result is the same.

My first thought was that the system crashed, and that only the ghost recovery system was restored, and a bootable CD was put into a CD-RW drive (and another DVD-RW optical drive on the computer) for the Ghost Restore system. However, the failure still exists after the system is restored. At this point I want to turn off the computer to find out the problem of hardware, press the eject key of the CD-ROM. Interestingly, you just hit another DVD-RW pop-up key. The strange thing is that the CD-ROM tray does not eject, after careful observation, the tray was found to be a CD-ROM jammed ...

I removed the faulty optical drive and switched it on again. The computer then goes into Windows XP normally. Disconnect the faulty optical drive, remove the card in the inside of the disc-this is yesterday with the computer to put in, the result is tilted on the card, resulting in the optical drive at the start of the BIOS can not return to the "ready" signal and make the system hang.

When the computer is started, when the BIOS detects that some parts fail to return to the "Ready" signal, it automatically hangs the system, which requires a step-by-step check on which part is stuck (or halt on item directly in the BIOS, select No errors, That is, the system continues to boot the system regardless of the device error. This can help to a certain extent to determine whether it is a hardware problem or system software problems, and also is, when the CD-ROM is also noted that the disc is tilted in addition to the CD-ROM will be stuck in the optical drive will damage the mechanical system.
