RAM problem laptop not working

I recently upgraded my ram from 4gb to 8gb after receiving some ram from a friend. After installing the ram, i turned the pc on, but the laptop came up with a black screen, before shutting down. I checked all the specs - laptop is compatible with SO-DIMM DDR3L which is the ram that I received (I think). After putting taking out one of the ram the laptop turned on but the screen was all messed up. The screen was green and red and was creating a split image of the Dell logo on startup except that it was green and red and was constantly moving. Any help will be greatly appreciated.

have you tried testing the old 4gb ram again and seeing if the screen still has the green and red tear? that doesn't sound like an issue ram would make, if anything that could be a loose cable possibly with the screen or even in the hinge of the laptop. If the 4gb ram works withouth the green and red then the next step would be to find out the ram compatibility speed and make sure its the right low voltage ram

also looking at here

http://www.dell.com/support/article/au/e...

you can see your laptp is compatible with ram upto speeds of 1600MHz if its an Ivy Bridge processor, or 1333MHz for a Sandy Bridge.

Note* you can't mix DDR3L with DDR3.

Hi @nathan2803 ,

Just verifying, what CPU is installed?

i3 -2xx0M, i3-2xx7M, goes with 1333 MHz DDR3 RAM

OR

i3-3xx0M, i3-3xx7U, i3-3xx9Y, i5-3xx0M, i5-3xx7U. i5-3xx9Y goes with 1600 MHz DDR3L RAM

Presumably you removed the battery before removing/replacing the RAM?

Have you tried the old RAM back in again to see if it still works OK?

If it does, what configuration was the old RAM, 2 x 2GB or 1 x 4GB?

Have you tried the other stick of new RAM into the first slot if it is the right type?

Here is an image taken from the owner's manual for your laptop.

Symptoms of a RAM Problem

When you first turn on your computer it runs fine, but as you go about your business you notice that its performance diminishes. By lunch time, websites take minutes to load and local programs run at a snail's pace. This type of gradual deterioration of PC performance, especially with memory-intensive programs, may be caused by a RAM problem.

Your computer randomly restarts while you are in the middle of something or freeze sporadically. It may also reboot almost immediately upon opening the desktop. This could be a sign of faulty RAM.

A blue screen with white text flashes before restarting. Blue-screen errors are annoying because you don't even have a chance to read the error message. Bad RAM is one thing that cause them.

Files—particularly ones you frequently access and save—seem to be inexplicably corrupted. RAM issues can lead to this problem, which can worsen over time. The file structure of your hard drive may slowly degenerate and you will no longer be able to boot your machine.

Your attempts to install a new program repeatedly fail for unknown reasons. You try to reinstall the operating system, but keep getting odd error messages.

There are certainly a variety of problems that could cause the issues above, but faulty RAM is an often-overlooked root cause of inexplicable issues. If you have one or a combination of the above problems you are likely facing a memory issue.

What Causes Memory Damage?

Power surges can damage most computer components, including RAM. You should plug your computer and other expensive electronics into a surge protector. Make sure you know the difference between a surge protector and a power strip.

Before you handle any parts in your computer, make sure you ground yourself by touching a piece of grounded metal to discharge static electricity. Electrostatic discharge can damage your computer.

Excessive heat can cause RAM and other parts to wear out over time. Individual components can overheat, or heat from one component can cause damage to adjacent parts.

If you have overclocked any part of your computer incorrectly, it may cause damage in the form of excess heat.

Your memory module may have some fault that passed through quality control and worsened over time. This is the most likely cause behind a damaged RAM.

It is also possible that the memory module is fine, but one or more memory slots on your motherboard are defective, hindering the RAM's performance. The defect may even be so bad that it damages the memory stick.

 Diagnosing the Problem

If the symptoms started after you recently added more memory, the new module could be faulty. This seems obvious, but any time a problem begins after making a change, first check to see if the change caused the problem.

Your computer may produce multiple beeps or a continuous beep when you turn it on. These beeps can indicate many different problems, including being a symptom of bad RAM. Beep codes vary depending on the manufacturer of your BIOS. You can look up the beep codes for your specific computer to figure out its specific problem.

If you are not comfortable fixing your computer yourself, I recommend taking your computer to a local repair store rather than a big retail store. Big stores are in the business of selling additional parts, not fixing problems.

If you are an advanced user, there are diagnostic programs that can help you figure out if you have a memory problem. Your computer may have one pre-installed by the manufacturer or you can download a third-party program. The Windows Memory Diagnostic by Microsoft is also good if you suspect memory problems on a Windows PC.

If the above programs indicate your memory sticks are functioning, but you still suspect a RAM problem or if you need to find which memory module is the problem, you can try removing the modules and placing them in different slots.

One way to think of the difference between these different types of storage is to imagine them as paper documents. The cache is a list of names or numbers you constantly refer to and keep close at hand. A folder full of papers you may need for your current task is similar to computer memory or RAM. The file cabinet full of folders for all your projects is like the storage on your hard drive.

Memory problems are less common than other computer problems because memory sticks have no moving parts and thus fewer points of failure. However, due to this many RAM problems go undiagnosed. Memory usually will last longer than other computer components so manufacturers offer longer warranties for it than other parts. If you buy brand name memory it will likely have a lifetime warranty.

Fixing the Problem by Removing Memory

To remove a RAM module you need to press the tiny levers on each end to release it.

Test each of your memory modules one at a time to find which ones are bad. When you find the sticks that are bad you can order replacements. It is possible all the memory modules are damaged if your computer experienced a serious power surge.

If all the memory modules appear bad, then the problem is likely with the memory slot itself. Try testing each memory module in each of the memory slots to find if one of the slots is faulty. To fix a faulty slot you would need to replace your motherboard.

When replacing a module, make sure the indention on the bottom is lined up correctly with the slot and then press it in until you hear the levers snap. Note that some levers do not make a snapping sound.

Other Possible Problems

RAM problems often go undiagnosed, but they also can be misdiagnosed. Some common problems that have nothing to do with memory can cause the symptoms listed above:

 

Many of the symptoms listed above can actually be caused by a hard drive problem. You can run a utility called CHKDSK by pressing the Windows button and R at the same time, typing CHKDSK into the dialog box, and pressing enter. Alternatively, you can click on Computer, right-click the drive you intend to scan, click Properties, then the Tools tab, and click Check now. Note you will need to restart your computer. Also, be aware this process may take an extended amount of time to finish running. If you hear your hard drive making lots of noise during normal operation, it may be the cause of your problems. Defragmenting your drive every few months is a good idea as well.

If the performance problems occur during graphic-intensive programs such as games or rendering, your graphics driver could be outdated. Be sure to always keep your drivers up to date.

Excessive heat in your machine can cause a variety of problems.

Random reboots can be cause by a failing power supply.

Dirt and dust can also cause issues that look like memory problems. It is a good idea to clean dust out of your computer at least once a year, more often if you have furry pets.

Your computer can also have a virus. Note that many people automatically assume any problem with their computer is caused by a virus and many large retail repair stores frequently misdiagnose hardware problems as viruses. Make sure you have a good anti-virus program and run scans on a regular basis.
