Question about Dell OptiPlex GX280 PC Desktop
On start up when it gets to the log on stage the windows logo comes up, the computer does one short beep and the num lock light will not turn off, the keyboard will not operate so I am unable to log in.
The only thing I can think of is that you might have some muck under the keyboard. See if you can get someone to clean out the inside of your keyboard. Hope this helps.

If you boot from the XP CD and choose the first repair option it will load to a DOS prompt. From there type "chkdsk /r" and press enter. This will run checkdisk on your hard drive and repair any problems that it finds. It will take 45 minutes or more depending on the size of your drive. Once it finishes type exit to reboot and remove the CD. Your computer should boot normally.

Try restoring your system bios to factory default and this may fix your problem. If not- post again with results and we'll go from there.
Entering System Setup
Turn on your computer.
When the blue DELL logo is displayed watch for the F2 prompt to appear (black screen / white text).
Once this F2 prompt appears, immdiately press F2 .
The F2 prompt indicates that the keyboard has initialized and is detected. This prompt can appear very quickly. Watch for it to display as the screen powers up, and then press F2. If you press F2 before you are prompted, this keystroke will be lost. There is a small window of time to do this before Windows starts.
If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft Windows desktop. Then, shut down your computer and try again to enter setup. At setup check your bios version. It may need to be flashed (upgraded). Select load factory defaults to see if that will resolve your PCI issues.
