I had 256MB RAM DDR PC2700 in my PC and I installed a 1GB stick. I had run a memory needs check from Crucial.com and it told me what I needed and I also checked the actual label stuck on the RAM in the PC.
The connections on the RAM look ok - not damaged - and fitted into the slots without a problem.
Now when I power up the PC the button goes green and the fan on the motherboard kicks in for about 5 seconds and then it stops and the light goes off and a few seconds later the button goes green again and the fan starts again. This keeps happening until I hold the power button in on the PC to power it off. I checked all the wires and connections and can't see find anything loose. It doesn't beep at all.
Any suggestions please?
