Added Ram problems

[as6670]

I have the Asus P5LD2-SE mobo and just got another 2gb of memory to add to the PC. I went as far as getting the exact same make of memory that is installed. My problem is when i add all 4GB of memory the PC refuses to boot up. It just hangs when booting and wont even let me get into BIOS. Im at a loss with what the problem could be. I did confirm with MESH that the mobo could take the full 4GB and also checked through the mobo manual before buying the extra memory. Strange thins also is it boots up with 3GB but not the full 4GB...any help or ideas are appreciated.

Will the new memory run by itself? Also, can you list ALL the information from the stickers on each set of the memory? And, what power supply are you using?

I have tested the memory in various positions on the mobo and it will boot up with no problems with 2 and 3GB...as soon as the 4rth stick is added it will not boot up. Asus and MESH have confirmed that the PC can go up to 4GB of memory.

600 watt power supply

stickers on all sticks say the same:

1GB DDR2 PC2-4200 /533MHz RAM

Right, but I need more specific information. I need ALL the information from the stickers on the memory. And, I need to know what specific PSU you are using, not just the wattage rating.
