Having problems with bootups, broken memory components, or PC compatibility issues? Try these solutions to common RAM troubles.

You managed to install your newly acquired RAM. But just when you thought everything was perfect, you noticed a glitch in the system. If you've come this far, why not try to fix your own PC before you panic and call a technician? Hopefully, you've left the cover off your PC and still have your grounding strap on. If not, review our directions and static precautions before you do anything.

My new RAM won't work!

• Certain characteristics, such as speed, size, error checking, type, and so on, determine whether your computer will accept or reject a memory module. Take a close look at the memory you bought. Make sure it meets your computer's requirements. If you're having problems, you may have simply selected the wrong type of RAM for your system.
  
  
• Double-check the installation of the memory modules. They go in only one way, so make sure that the modules are inserted completely and are latched into place on the motherboard.
  
  
• Check the manual that came with your motherboard or system to make sure you've followed all the recommendations and specific installation procedures. Some systems require that memory either be inserted in a particular order among the sockets, in pairs of modules, or that a jumper on your motherboard be set for the RAM to function properly.
  
  
• Check your PC's CMOS setup. You may need to make changes to the setup so that the new memory can function properly. Even if you don't make any specific changes, save the current settings anyway when you exit the CMOS setup. This will force it to recalibrate and find all of the installed RAM automatically.
  
  
• Finally, the memory may be defective. Try the memory in another compatible PC (if possible) to see if it works. Otherwise, return the memory for replacement.
