AMD says the core to AMD Puma is energy efficiency, each of the cores of the AMD Puma will be able to run at different speeds to help achieve a balance between efficiency and power , and amazingly will be able to shift speeds while executing threads.All AMD Puma based products will be based on the Griffin processors and RS780M, along with a WiFi adaptor and an optional graphics card. Griffin processors, which will be a dual-core offering, will be equipped with 1MB of L2 cache per core and support up to 8GB of DDR2-667 and DDR2-800 SODIMM RAM.

Today one of my worstation desktop gave me a problem. Everytime the desktop in turn on, there is a beep beep sound, and there are no display on the monitor.

The No Display problem when booting is one of the common and complicated problem in troubleshooting computer. Usually the No Display problem when booting can be associated with several major problem with the computer, such as faulty motherboard, faulty graphic card, faulty RAM Module, mostly hardware.

In this case, the beep beep sound when booting gave me the idea of what is causing the No Display problem when booting.

Most of the motherboard nowadays will give a beep beep sound the there is a problem with the RAM Module. And in my case, the culprit is the RAM module.

It seems that the RAM module has oxidized a little bit, and this is causing minimal contact or no contact with the RAM Slot module, which give the desktop workstation a no display when booting the computer.

A quick fix this no display problem with beep sound caused by the RAM Module is simple.

Get yourself a rubber pencil eraser, and clean the contact point of the RAM Module (bronze color). Make sure to use gentle force when cleaning. After cleaning, make sure that there are no remaining residues of the eraser remain on the RAM Module.

Install the RAM module back into the RAM module slot.

This is one of the solution for the No display when booting problem.

Some of the motherboard manufacturer has equipped their motherboard with different beep signal to indicate what are causing the beep and the problem. This usually goes for high end motherboard.

Today one of my affliate computer cannot boot after installing a new Hard Disk Drive.

The specification for the computer are a decent old Intel Celeron 2.4Ghz (socket 478) with 256MB DDR333 PC2700 RAM. She use the computer to run a cyber cafe server monitoring software to monitor client in her cyber cafe. The new Hard Disk Drive is an old Maxtor DiamondMax plus with 40GB capacity and was installed as a second Hard Disk Drive.

After installing the second Hard Disk Drive, the system failed to boot, and hang after detecting boot device, sometimes the system would hang during Windows XP loading screen.

By doing several diagnostic, I found out the main culprit which is causing the computer cannot boot after installing the new hard disk drive is the Power Supply unit. It seems that the old Power Supply Unit cannot cope up with the resource required by the second hard disk drive.

The problem was solved immediately after replacing the old power supply unit which is causing the computer cannot boot after installing the new hard drive with a new Power Supply Unit.
