Question about HP Computers & Internet

1 Answer

Installed 2 GIG Ram memory into my Pavillion a1240n which had 1 GIG. So now it has 3 GIG. My computer did not start. Checked the green light and it was flashing. So I went to the HP troubleshoot web site and it said if green light is flashing then something is wrong with motherboard. To troubleshoot the problem it said to disconnect the main harness to the motherboard. Light stayed on solid green, then I connected the main harness to MB and the compuer worked fine again. Unfortunatley my house power went out and my computer did not start again. I had to perform harnes disconnect and connect again. What is wrong with my computer?

Is there a limit on your motherboard's memory capacity? if you exceed it, it won't work properly. that's a lot of (unnecessary) memory

Once you installed the memory, did you enter into the System BIOS Setup screen? Do this and verify that the system recognizes the newly installed 2GB RAM. This should let the system access the new memory once you boot.

Hi, my HP Pavillion a1240n won't start up... the wall plugs work and the power supply is plugged in but no lights are showing. I've also been flipping the switch beside the power supply at the back, and...


There are only certain items that will not power up a machine. 1. The power supply itself could be gone. 2. Check your ram. 3. Your hard drive. In most cases it is the power supply. Take out the power supply from the machine and plug it in to a wall socket. If it starts that it is not the power supply. If it doesn't start replace the power supply.

Can I install one (1-gig) memory stick instead of 2 match pairs (only have one) this is to replace two 256 sticks?will it preform at 1 - gig memory


Yes.

The Maximum Total Amount of Ram Memory is 2GB.
(2048MB)
The Maximum Amount for EACH ram slot is 1GB.
(1024MB)

Ram should be installed in Slot 1, when using just one stick of ram.
This is the ram slot closest to the Processor.

The Processor reads ram memory that is installed in Slot 1, first.

This is Dell Support, and the main support page for the Dimension 3000 desktop computer,

http://support.dell.com/support/edocs/systems/dim3000/en/SM/index.htm

In the list left-click on - Technical Overview

Now click on - System Board Components

Number 1 is Slot 1.

Note*
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate computer hardware components inside a computer.

Work on a table.
After you have opened the computer case, and BEFORE you remove that ram module from it's anti-static protective bag, TOUCH the metal frame of the open computer case. (Power unplugged from computer)

This will relieve your body of static.
Ignore the above if you are already aware.

DDR2's only showing half installed RAM


IF THE SYSTEM SAYS YOU HAVE 1GB RAM THAN YOU HAVE 1 GIG OF RAM, EVEN THOU SOMEONE TOLD YOU YOU HAD 2-512MG=1GB.

HERE IS HOW I SEE WHAT YOU ARE SAYING YOU HAVE 2-DDR-2 1 GIG STICKS THAT MEAN IF 1 IS INSTALLED THAN YOU HAVE 1 GB AND IF YOU COULD GET 2 STICKS WORKING TOGETHER THAN YOU WOULD HAVE 2GB RAM.
1 CHIP SET = 1GB RAM
2 CHIP SET = 2GB RAM

YOU MOTHERBOARD MAY NOT ALLOW THAT MUCH RAM, OR WHAT I MEAN THE BIOS MAKE UP THE AMOUNT OF RAM.

TO RULE OUT ANY BAD CHIP SETS OR GOOD RAM OR BAD RAM.

TAKE THE PEACE OF RAM THAT IS WORKING OUT AND REPLACE IT WITH THE OTHER PEACE AND SEE IF IT WILL RUN.
IF IT WORKS THAN LEAVE THAT ONE IN PLACE AND INSTALL THE SECOND PEACE IN THE SECOND SLOT.
IF BOTH CHIP SET ARE GOOD THAN BOTH SHOULD WORK OKAY TOGETHER.
IF THERE IS A PROBLEM, IT MAYBE SOME DUST IN THE MEMORY LOTS
OR THE SLOT MAYBE DAMAGED.
OR
THE CHIP DESIGN LAYOUT MAYBE THE OPPOSITE SIDE, THIS MAY MEANS THE CHIPS MAY FACE EACH OTHER, OR FACE OUTWARD FROM EACH OTHER.

Have a compaq presario sr2170nx....installed 1 gb memory but not showing up. swapped the memory sticks positions and restarted but still wont show up.


If you do not get the right memory for your computer it will not work. the memory you need is listed in the table below. And pay attention to the max amount of ram. Your system can only hold 2 gig and it comes with one gig installed

Component Attributes Memory Installed 1 GB Maximum allowed 2 GB (2 x 1 GB) Speed supported PC2-4200 MB/sec Type 240 pin, DDR2 SDRAM

One of the ram isnt recognised???


This is likely a memory timing incompatibility. You can go into the BIOS settings of many motherboards and set the timing specifically for each RAM slot, but without knowing exactly which piece of RAM you have I can't tell you what to set it at. You could use the utility CPU Z, install one stick, run the utility and write down all the memory information, then install the other stick and write it down too. Then go into your BIOS and see if you can set all of your specifications to match the memory.

Of course if you could find someone to swap sticks with that would be easier. Some motherboards are more picky than others about which sticks they work well with, name brand manufacturers are more picky than aftermarket in general.
