I am upgrading the RAM in someone's PC made circa 2004.
It already has 256MB of DDR PC2700 RAM (the original amount).
There are three slots total.
According to crucial.com, they do not have to be matching pairs.
When I took the 256MB out and put in three sticks of 512MB DDR PC2700 RAM, the machine would freeze up after a few minutes.
I could boot into Windows, but the mouse pointer would freeze and I'd have to hold in the power button in order to reboot.
A couple times, I got a blue screen of death saying the problem could be recently installed hardware, so I opened the machine back up and made sure all sticks of memory were snapped into place properly, which they were.
So, I put the original 256MB back in its original position and tried adding just two sticks of 512MB.
Is the motherboard maybe not powerful enough to handle more than 256 or 512?
If anyone has any idea of what might be causing this and how I can remedy it, so I can get 1.5GB of RAM installed on this machine, would be most grateful for your help.
Crucial is saying the max memory for the machine is 3GB, but maybe they're just basing this on the fact it is three slots.
Crucial said it can't determine the manufacturer, model, etc. since it's a homemade PC.
Thanks again so much for any direction!
