Just bought 2x2gb OCZ 6400 DDR2 to replace my old 4x512mb corsair 6400. Removed all the old corsair sticks and tried the new OCZ in the slots that the manual tells me to use, didnt work, so I tried every different combo of the 4slots still didnt work.
Basically what happens is; I press the power button the computer starts(fans spin etc) for 3~5seconds then it swiches off, then repeats over and over. On/Off/On/Off
Installed the old 512mb sticks and it boots fine.
Any ideas guys

Try each stick individully to see if one of them is faulty.
