There are two ways to determine if a computer has a base 64k RAM failure: If you boot up your computer and hear three long beeps and get no video or if the blue screen of death indicates it. More often than not, your computer will not load if you have this type of RAM failure so the only way to pinpoint it is to listen to what your system is telling you when it boots.
A base 64k RAM failure is an old message leftover from the days when IBM ruled the computer industry. Most computers only have 64k of RAM installed in them in the beginning, if something went wrong with the RAM, you would have a base 64k RAM failure.
Nowadays some systems depending on the motherboard, make up and RAM will alert you to this type of failure. It basically means whatever RAM you have in your system is failing somehow. This failure could be due to the RAM being inserted improperly, defective RAM or somehow the RAM sticks became dislodged.
The first step if you suspect you have base 64K RAM failure to turn off your computer and unplug it from the wall. Open up the case and remove the RAM completely. Let it sit for about a minute and then place one stick of RAM in, power the system back up and see if it boots up properly. This will narrow down which stick of RAM is causing the issue.
If you plug multiple sticks of RAM in and the system boots up normally, this most likely means the RAM was dislodged and just needed to be put back in properly. If you cannot get your system to load without seeing the base 64K RAM failure or hearing your computer beep, you may want to take it into a repair shop to have it looked over.
