It could be dust in the sockets, you could try reseating the RAM, or it could be an error in a memory stick.  Try testing the RAM with memtest (it's common to linux distributions and LiveCDs.)

I have a Packard Bell desk top PC In 2006 I Installed windows vista I noticed I needed a 512 ram as I had 256.I bought a 512 ram I knew were to install It ,I took the 256 ram out and carefully put In...


You put in the wrong type of memory. Put the old 256 back in the computer should power on with no beep code(or all good beep). If this is correct make sure to obtain the same type of memory as the 256. Also both slots must have the same RAM. You cannot have a 128 with a 512. They should both be either 128 or 512.
If you are using Vista you should have a minimum of 1g RAM.

Have a pc098a-aba,there are four slots for ram,i have 2 256 and 2 512,in what order do they gi into the slots


There are only two combinations depending on the exact board and chipset used

either 1 and 3 should be a matched pair and then 2 and 4

EG
1=512
2=256
3=512
4=256

OR

1 AND 2 = 512
3 AND 4 = 256

If they are DDR then watch the bios setting for options and turn off ECC if it is there.
Also whilst booting up if they are matched then there will be an extra line of text on screen during initial boot that tells you it is running as dual channel

Which memory ram for amilo pro v7010


http://www.fujitsu-siemens.ru/Resources/123/2080773523.pdf

Here's a link to the Data Sheet with the specifications to that Laptop in Adobe Reader format.

Looks like your Laptop came with either 256 or 512 MB of DDR SDRAM and it is upgradable to 2 GB of DDR SDRAM.

You can check to see exactly how much RAM your computer came with by going to Control Panel, double-click System and it should tell you how much RAM you currently have in the System Properties box.

The motherboard has 2 slots for RAM, you you could add a second 256 MB or a second 512 MB stick of RAM. Or if you wanted to upgrade to the 2GB of maximum RAM this computer handles, then you can take out the RAM chip(s) that is installed and install two 1G DDR SDRAM.

yes, a 400 mhz processor can run windows xp, but you will want to have a LOT of ram. i would not recommend it unless you have at 256-512 or more ram.

windows 2000 can get along with 128-256 ram.

Sdram capacity


its that 512 mb total capacity for your computer memory?? if so read this:
To find the total amount of RAM that can be added , subtract the amount of RAM currently in the computer from the maximum amount of memory the computer can hold. For example, a computer has 256 MB of RAM. If the maximum amount of memory the computer can hold is 512 MB, then 256 MB is the amount of RAM that can be added. this info from the HP website , to find out more , go to http://www.hp.com/support , enter the model number , and look for more information about your computer specs, hope this helps , please rate & thanks AJ
