I have a desktop having Mercury PI845GLM-P V6.0 motherborad. It runs with 256MB DDR RAM. The sticker on RAM shows "PC266 CL2.5".
Now I have bought Transcend 1GB DDR RAM. The sticket shows "1G DDR400 DIMM 3-3-3"
When I insert the new RAM (and removed the old 256 MB module), the computer starts and stops in 3 seconds, then it automatically starts in about 5-6 seconds and this goes on.
What is the problem ? How to solve the problem ?
