Hi kawire,

Especially with a compaq like this... make sure the RAM is compatible with your motherboard. Otherwise, your new stick of RAM might be faulty.

Hi Kawire,

Have you recently installed any other operating systems?  The reason I ask is because that error is usually related to the boot.ini file.  Have a look at this page:


Also, when upgrading RAM you should make sure you purchase compatible chips.  This is especially true with Compaq systems.  

Try www.kingston.com and www.crucial.com for product selectors that will show you exaclty what is available for your particular computer.

Search the HP WebSite for compatible chips, or the correct part number, and order it based on that information.

Best Regards !

What OS do you have, if it allows you to boot with just the new memory (32mb I assume) and see what happen.  That would be the quickest way.

May I suggest you goto www.crucial.com and you can put in your exact brand/model # and they will give you a guarantee that the RAM they suggest will work.

You should also check if the memory is single or double sided...this is due to the fact that some motherboards have problems with single sided modules.

Like others, assume you are adding a 32MB stick of RAM.

Could be that you are mixing EDO RAM with SDRAM or 32MB stick is faulty.  In either case, you will need to purchase working, appropriate module for your PC.  Crucial will be the best bet for older systems like yours.
