Memmory problem ' dead motherboard

i got the same problem on both computers
and i try'd to use other ram slots still - not work

i resently did this you can do this
open up your case and pull the cmos battery out. It is a quarter size batter like you put in your watch. Push the metal clip and the battery will pop out keep it out for about 5-10 sec then put it back in. Then start your system this is going to reset your cmos withch after doing so the computer will boot up with a beep or 2 caint remember. Then it is going to ask if you wont to continu or enter setup "bios" select continu. By pushing the key reqester and then seleck start windows normaly or start windows with last known good config. There done let me know how it goes
like i said i whent thru the same issue but i whent in and changed how much power whent to my dimms "ram slots" and it shut down and did the same 3 beeps and no moniter no keyboard no mouse give it a try

Please provide links to the RAM used in both systems so I can check if they are compatible.

first computer:
1 stick of kingstone ddr2 2gb ram
intel dg31pr


second computer:
DH55pj
2 sticks of 2gb ddr3 ram kingstone

The 400W PSU on the second system is small if you have graphics card added or OC.

Question - what happens if you use the 'old' RAM the worked before??

so no one has an idea?

thanks anyone , i belive that this ends here , thanks alot for helping me
