I have a problem with my pc.
I have one stick of ram thats in a1 and it wil boot, but when i put my second ram stick in b1, it won't boot and even post, im confused.
To check if my ram is not broken.
So when i put that "broken" ram in slot a1 it wont boot, but that working ram stick boot a1. Everthing works the cpu is not bent everthing is good and it also beeps not when i out that "broken" ram. any solutions i have already clear cmos and it will turn on but nothing happend, and i see nothing bent on my ram stick should i return it?
