Display Problem with Twinmos DDR RAM

Hi Broad,

Following this steps will help you to your problem.

Step 1: Back up all important files and data. You should be doing this on a regular basis anyway but if your computer is showing signs of failure don't wait any longer to perform this job. 

Any one of these can indicate a problem with the RAM module or something connected with it. 

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. 

Step 2: Gather all the documentation that came with your computer, memory modules or MOBO (motherboard). You need information on make and model numbers, together with installation guides. If you are missing anything visit the PC or MOBO manufacturers web site. Most have excellent online documentation. 

Step 3: Do you have the correct RAM? Check the MOBO or computer documentation for the type of memory module you should be using. Compare this with the memory module you have purchased. Look at the memory module; does the information on the module match with the sales invoice (have they sent you the correct product)? If you bought a name brand computer has the RAM purchased been tested on that particular computer?

NOTE: Before the computer case is opened make sure that power is switched off and disconnected, press and hold the power button for 30 seconds to ensure residual power is lost and make sure that you are grounded to avoid damage due to static electricity. Use a grounding wrist strap or touch the metal case to discharge static electricity. 
Step 6: Is the RAM installed correctly? Some MOBOs must have their slots filled in a special sequence. Sometimes DIMMs must be in a specific sequence.

Step 4: Remove the memory modules from their slots. Take the opportunity to clean the slots on the motherboards and the memory module connectors. Use compressed air to blow dust away and clean contacts with a soft cloth. Don't use a vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components. Don't use solvent that may attract dust and never poke things like cotton buds in to slots. Check the memory module and memory slot contacts. They are either tin or gold.

The color will tell you which they are. Mixing tin and gold can result in corrosion that prevents proper contact. Look for any sign of physical damage to the memory module, memory slots or the motherboard. With the last two you are looking at replacing the motherboard. 

Step 5. Reseat the memory modules. You should hear an audible click when they are in place. Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard. 

If you are still experiencing trouble try the following. 

Step 6. Swap modules in to different slots. If you have more than one memory module try different combinations or one at a time. This might identify a faulty component. 

Step 7: If you have changed or upgraded the memory modules try taking your system back to its original configuration. Does it still work? If yes then suspect a fault or compatibility problem. If no!! Sorry but you may have damaged the motherboard. 

Step 8: If your compute isn't recognizing all of your RAM it might be a problem with the BIOS. Check with the motherboard or PC manufacturers web site for possible BIOS upgrades. Word of WARNING – BIOS upgrades can seriously damage your wealth. Make double sure that you have the correct BIOS update for your motherboard. Flash the wrong upgrade can result in needing a new motherboard. 

Step 9: Check for viruses with an up to date virus checker. Some viruses cause problems that look like memory errors. 

Step 10: Try removing recently installed hardware or software. Sometimes operating systems misinterpret problems as memory related. 

Step 11: If you have tried everything a still suspect a faulty RAM module there are several good programs that will test your computer. Typically you must create a boot disk to use when restarting your computer. This helps eliminate the possibility that it's operating system or other software problems. Three options are – 

Step 12: If finally you need to use a computer technician or phone a technical support line make sure you have written down everything you did and the result. It can save you time and money. 

Display Problem with Twinmos DDR RAM

If you don’t have display, check the video cable and make sure it is connected securely on the video port. If you are using a dedicated video card and your video cable is connected to this video card, transfer the cable to the built-in video card of your motherboard. Start the computer then see if you have display on startup.

If you have display then there is a problem with your dedicated video card. Remove it from the slot and use the built-in video card for the meantime until you buy a new dedicated video card. If the memory module is not working on one slot, try transferring it to another slot.

On the other hand, if the same memory module is working on another computer, this could indicate a problem with your motherboard’s memory slot. The memory slot can’t be removed and replaced. If the problem continues, the entire motherboard has to be replaced with a new one.
