progress bar doesn't appear
I am using Dimension 4700.
OS is Windows XP Professional.
The computer often reboot suddenly. Sometimes, after selecting restart at the desktop, normally the blue DELL letter and a white progress bar appear.
Though, the blue DELL letter appear but there is no progress bar. Therefore waiting for ten minutes nothing happens.
What caused these problem.

Cleandesk,
Yes. What is the status of the diagnostic lights on the rear panel?

Cleandesk,
What you describe indicates the system motherboad is failing its Power On Self Test (POST). This can be caused by defective memory, a defective power supply, an overheating Central Processing Unit (CPU), lint buildup on a cooling fan and the list goes on. When the system does this, check the system diagnostic lights. The rear panel location of the diagnostic lights are shown in the Owner's Manual located here: support.dell.com/.../Y69490LRs.pdf
The diagnostic lights are described on page 37 of the Owner's Manual.
Let us know what you find. It can give us some clues as to where you should begin troubleshooting.

Thank you. I've read the manual.
By the way, is the condition after turning on the machine, the blue Dell doesn't appear and directly go to a black screen with a under bar blinking at the top left, the same as what you mentioned above?

Tony,
The diagnostic lights show green, green, green, yellow from A to D.
Though, sometimes there is no problem and able to boot.
Is there a possibility that I am trying to insert a card to PCI express x1 slot.

Cleandesk,
When troubleshooting, disconnect all peripherals except for keyboard, mouse and monitor. Recently, I had two laptops that were giving a disk error on boot and requesting permission to run chkdsk. Both of these laptops had a USB wireless adapter for an external keyboard and mouse. Moving the wireless adapter to a different USB port solved the problem. What causes this is somewhat of a mystery. While the BIOS checks for bootable USB media on startup, the wireless USB adapter should not have been seen as bootable media. This same sort of problem could occur if you have a USB printer connected that has slots for flash memory.
As for the possibility that you are trying to insert a card to PCI Express X1 slot, that would depend on whether or not you have added additional PCI Express cards into your system. If your system is configured as it came from the factory, I don't think that should be the case.
