Hi,
Yes a bad or an improperly seated ram-stick will surely result in a similar behavior.
What type of computer is it: manufacturer and model?
Ram: manufacturer and model, size and how many?
Unplug the power cord from the wall outlet, make sure that the ram-sticks are properly seated in their respective slots.
Restart the computer.
Still he same problem? Unplug the power cord...
Try to remove the ram-stick you suspect is giving this problem and try if there are one more.. that is still in place.
Test again, if not exchange the ram-sticks between each other and try again.
Best regards from Sweden
