Hi, welcome and thank you for your question. My name is XXXXX XXXXX I am glad to assist you today.

Is your system beeping when you turn it on? Also, have you tried to just install 1 memory stick at a time?

Please let me know so that I can help you further.

Best regards,

Hello Jess,

System beeps yes ( Once only), and I have tried just 1 memory stick. No change in status.




Are you using an external video card in that computer? If so, please try to remove it, and use the built-in the video card. That is, attach your monitor to the VGA port in the motheboard side, do not use any external video card as a troubleshooting step.

Keep me posted.

There are no external Adapter Cards. Monitor is a connected to the Motherboard IO port DVI-D.




Please try to remove the RAM, all ram sticks. With a pencil eraser, gently wipe the golden pins of each ram stick.

Do not put back the RAM. Disconnect the hard drive power cable and sata cable also. Now, without the memory sticks and the hard drive, try to turn on the computer.

Is it beeping? What is the beeping pattern? Do you see anything on monitor?

Keep me posted.

okay now something strange has happened. I thought that I would place an XP CD in the drive and switch on. The XP Disc has booted and files are being setup to install the system. However, I have not done anything to the Motherboard. All I have displayed on the screen now, is the BLUE SCREEN of death??


What happened? Did you not unplug the hard drive from the motherboard? Also, did you not remove the RAM?

Jess, Yes uplugged the Hard Drive, removed ram and reset. One beep only, is the reply from the Motherboard. System now reports that Harddrive not configured?

I am glad that the system is no longer showing the A2 error in the board and that it is starting to boot with something on the monitor.

Now, please attach the hard drive back, and then install the RAM sticks. When the system boots, access the system BIOS and then configure it to your preference.

Load the disc and then try to install it.

Now, if you are using Windows XP and and getting the BSOD, I suggets that you try to change your HDD modes. There are options for the HDD that say something like SATA or IDE, please try to change that setting and test which onesis working when doing teh Windows XP installation.

I hope that helped.
