    That's not the case. It had worked fine earlier that morning (I had performed a backup on the entire computer - just ini case - overnight; first time ever; computer had no issues/problems-i just thought it woulfd be good to upgrade the memory. Took it in; they had me go & purchase some ram at Fryes - Best buy (Geek SQUAD) installed the first set of new ram; it didn't bootup; i then went ad purchased a second pair of ram; same thing computer did not bootup. Hindsight - should have had them turn it on & run it first before anything else.

    logical response; but we already worked on that- tried two new sets of ram

  • danielduckyd Apr 13, 2009

    logical questions; you'll hate my answers;
    (1) Tech said it was my motherboard - it had went out. (But I had no problems until they touched the computer.)
    (2) Screen is totally dark; no bios, nada! Push de buttons - nada!
    (3) Tried two(2) news sets of rams - both didn't work. Tried original ram after two attempts with new ram; computer didn't function.

    Tech had me go & get 2nd set of ram - because he thought the ram wasn't "clocking" down; nope! Computer failed to work.

    Some help by the two techs at the store, eh?

    I didn't need their help; i can screw thigs up myself..ha!~

    It is very difficult to determine if they jacked up your computer or what? I hope they didn't burn *********** board in the process. Are you able to go to your BIOS? reboot and press F2 or watch the message that appears on the bottom of the screen and make sure that your boot drive is set to C...And , did you make sure that that was the right type of RAM for your machine?...Finally, if you could get a hold of the Old RAM so you can put it back to see if it works.

Memory upgrade aba d8x43ua


You can upgrade, your RAM, with the same voltage, and brand, but also brands like Kingston, or Samsung, Corsair, are good ones!
always, look on places like best buy, or radio shack for those.
I prefer new RAM instead of used.

Ram upgrade


The best way to find out for sure how much ram your computer could take is to do a scan with the Crucial scanner.
Go to www.crucial.com and click on "Scan My System" 1539d96.jpg

Now you're going to download the scanner. Click the checkbox to agree to the ToS and Download the Scanner.

Depending on the browser you're using, you're going to click "Run" or "Save". I'm using Google Chrome so I only got the "Save" option. Click or double-click to run the scanner.

Allow the program to run if it asks you if you're sure you want to run it.
Crucial gives you a recommended max-it-out RAM config if you wish to max out your memory.

However the pricing can be quite a little steep, so if you just want information about what kind of RAM your computer needs and what it would run best with, the section below carries this information (directly below from the above screenshot).

You can take this bit of information to your local Best Buy or Fry's or any preferred computer store and they can help you with what you're looking for.
Hope this helps :)

Memory upgrade


The memory should be DDR II Ram. To find how much ram you have simply click on Start then right click on "My Computer" and click properties. Chances are you have 512 ram. It will tell you in the lower right hand side along with your processer and windows version. Once you have found out how much ram you have, turn off your computer flip it upside down and pull out the battery. Then you should see a cover with one or two screws in it that measures about 3 inch by 4 inch. Remove the screws and take the cover off. This is where your memory goes. If there is 512 memory in your computer you will either have 1 512 memory stick or 2 256 sitcks. Remember that any time you upgrade memory it is best to take out the old memory and replace with either one stick of higher ram or two of equal ram. Never mis a 512 and a 256 or 512 and 1gig ect. Take the ram stick/sticks out and bring them down to the store with you just so as to get the correct memory. Also, remember when you replace the memory, if you are just upgrading to one 1gig stick to put it in the A DIMM slot. This is the primary ram slot.
