Inspiron 9400 does not turn on!!

My inspiron 9400 will not boot. The only functions I can see is the battery light comes on when plugged in to indicate that it is charging, and when I press the power button the power light comes on for 5 seconds then goes off, thats it. I thought this problem was the board earlier, so I replaced it with a tested motherboard and am having the same problem. I have also tried booting with just AC adaptor and just battery, no change. Right now my only idea is the CPU, is this feasible? Can somebody help me with this?

Thanks

I could be the CPU and it could also be your memory,

can you try some different sticks or try using one at a time.

try without the hard drive or CD drive installed as well.

I figured it out, I just took the whole thing apart and put it back together again. I noticed that the cpu wasn't locked down all the way.

Thank you for your help.
