Memory Slot short

I tried to upgrade the memory. I mistakenly put DDR2 memory. After I powered on I smelled somethig burnt. I thnk the wrong memory made some parts short. Then the computer shows nothing on the screen and no HD access.
Are there any method to define which parts need to be replaced?

Thanks!

Probably get a techician to have a look at it. If u smelt something burn, then most likely it was due to a short circut on the motherboard in which the motherboard is faulty.

Take out the RAM and power the PC back on again. If it doesnt turn on, then the motherboard is faulty and you will need a new one.

My e-machines will not let me upgread my ddr2 1eb memory


That Machine would take DDR2 PC2-5300 upgrade chips. The max that system could take would be two 1GB sticks for a total of 2GB or 2048MB of memory. Memory is fairly easy to damage with static discharge and is also very easy to not put in all the way. When putting it in, unplug the power from the computer, push and hold the power button for 20-30 seconds to help discharge power from the computer, Line up the pins on the memory and push them into place till the little arms at the sides of the slot pop up and click into place. I'd install one chip at a time, powering the machine up after the first chip to make sure it works, then starting over again. The only time I'd install both chips at the same time would be when installing a memory kit (two or more chips in one package), in which case, install both chips before powering it on.

I want to upgrade memory


DDR2 PC2-5300
icon_detail.gif Memory Type: DDR2 PC2-5300, DDR2 (non-ECC)
Maximum Memory: 2GB
Slots: 2
Each memory slot can hold DDR2 PC2-5300 with a maximum of 1GB per slot.*
*Not to exceed manufacturer supported memory.
just to be sure

If you're not sure if a module is right for your system, use the Crucial Memory Advisor tool for a list of guaranteed compatible modules.


first you will need to select the manufacturer from a drop down list then select your product line from a drop down list then select the model then click find it will take you directly to compatible ram also you will have an option to scan your system


you should always ask for a guarantee on the compatibility before making any purchase and try to buy for working pairs if possible


hope this helps

My evo does not run bios


Maybe you have a Static Charge Buildup. Remove thePower Cord, then Press and Hold thepower button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots. Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Can I upgrade my 2.8 Ghz CPU with the 3 2 GHz dual core 775socket BX80571E5800 CPU into my N1996 acer 671t desktop motherboard, and can I upgrade my 553/ddr2 ram with a 2nd 2G ddr2 800/ RAM (max 4x 1 G...


as long as the socket is exactly the same as the processor you are trying to upgrade to you should be good. As far as memory goes you can use a faster ddr2 chip but you have to find out what the maximum capacity is on each slot. Most newer computers can support 1gb+ per slot. Always make sure you install ram in pairs and in the proper slots.

Motherboard for compaq pcsr5109uk have upgraded to 1,5 GB this adding a 1 GB ram since doing this pc will not boot up,pc has said that the mother board has died this has only started since new ram have...


From what you have stated, the original ram memory was two sticks of 512MB.
It's PC2-5300
(DDR2 Sdram at 667MegaHertz)

When installing ram memory, and installing two sticks with one stick being larger, the larger stick of ram memory is installed in Slot 1.

This is the ram memory slot that is closest to the Processor.
(The Processor reads Slot 1 first)
On the motherboard it has DIMM 1 printed next to Slot 1.

The 1GB stick should go into Slot 1 (DIMM 1), and the 512MB stick should go into Slot 2 (DIMM 2)

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01077654&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=3457899

Scroll down for the motherboard illustration, and photo.

Won't boot up with the original ram memory installed again?
1) What type, and size of 1GB ram memory did you install?

2) What ram memory slot did you install it in?

3) Did you follow anti-static precautions BEFORE you put your hands inside your computer, and BEFORE you took that ram memory stick out of it's protective anti-static bag?

[Your body carries Static electricity.
Static will fry out (Short Circuit) the hardware components inside a computer.

You may not even see it, or feel it.
Poof!
No computer.

Computer unplugged from power, computer on a table, computer case open, TOUCH the metal frame to relieve your body of Static.

{A couch, bed, or directly on a carpet floor are HIGH areas of Static]

Before you answer my questions try this;

If the two sticks of 512MB PC2-5300 are still installed, follow anti-static precautions, and remove them.

Take a pencil eraser, and clean the gold plated contact pins on the bottom of each ram module. (Stick)

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

(The above example is DDR Sdram, not DDR2 Sdram. I posted the link so that the gold plated contacts are clearly shown.

DDR Sdram has 184 contact pins.
92 on each side.
DDR2 Sdram has 240 contact pins.
120 on each side)

Remove the eraser dust with air. Use a can of compressed air for computers, or air pressure from your mouth.

Reinstall the ram memory modules.

Computer unplugged from power, press the Power On button in.
Hold the button in for a count of Five seconds.
(Count 1001, 1002, 1003, 1004, 1005)

Let go of the Power On button.
Do this procedure two more times.

What you are doing is clearing CMOS Error Codes, and resetting BIOS back to the factory settings.

Plug the computer back into power.
WAIT 1 minute, then turn the computer on.

I await your findings, and answers to my questions.

Hi - I have a Allied AL-A300ATX motherboard. I'm


Usually memory chip or slot. Try refitting ram chips. Or only fit one, in each memory slot at a time.
Sometimes video code is mistaken for memory code so if a separate card is used ensure card is ok and, especially with agp, make certain it's in the slot properly.

How do I install a 2g stick of memory into gt5408 ? What nvidia video card can I use to upgrade from the Intel graghics card for around $100. ? Thanks in advance for your responses !


Gateway GT5408/H has 4 slots for memory. Each memory slot can hold DDR2 PC2-5300 or DDR2 PC2-6400 with a maximum of 1GB per slot. It will not support a 2GB stick.

ZOTAC GeForce 9600GT Eco 512MB cards are about that range and give you a good warranty as well.
