1801 Microcode Patch Error

I bought a Compaq Computer, 2.0Ghz, 256MB, 20GB for my College project. When i put the power on, it restarts almost immediately (so many times repeatedly). Then after such reboots, it successfully brings a message "1801 - Microcode Patch Error" and a F1-Boot directive. Pressing F1 boots properly. until next boot... the same problem. SOS

I upgraded the CPU in my Deskpro D510 to the fastest processor the model will take. After the upgrade, I got the 1801 microcode error. Downloading the newest BIOS from HP/Compaq solved the problem for me.

Click on Download at the end.

A small window will come up on the right.
Opening sp33313.exe
Click on Save File.

Another small window will come up on the left. In the wording at the top of the window tells you where the file will download to. You may wish to write it down.
It may have Desktop, or My Documents, or Downloads, in the wording.

Desktop: The file will be on your desktop screen

When you see the file name (sp33313) DOUBLE-click right on it
The Installation Wizard will appear. At the bottom of the next 3 small windows, click on Next, Next, and Finish.

If you are not asked to Restart your computer, close all windows, go back to your desktop screen. Restart your computer.
(Start > Turn Off Computer > Restart )

And follow the instructions here to upgrade the BIOS. I suggest using their instructions as they will be far more accurate than mine for this specific system and BIOS update.

These are very different CPU's, and you should make sure the board accepts the new one. Check the manual.
