my pc not boot up

Do a series of troubleshooting .
Step 1: Clear the cmos by removing the battery on the motherboard for 10sec and then place back into place .
Step2: Take out cpu and put back in . Apply thermal paste and fan with heatsink .
Step3: what's your power supply ?
Step4: Take out gpu and see if it boots .
Step5: check cables and make sure everything is in okay .
Step6: test bench it , could be a grounding issue
 
I'm not sure but it's definitely the best place to start. Make sure there's thermal paste and then bolt it down. Once that's done try booting up with only 1 stick of RAM.
 



my power is EA-750 ANTEC
are you sure its not problem of cpu because is ES?
 


if i boot many times my cpu burn without cooler?
 
There's no real good way to tell without the right tools. If you can't get the system to power up with the cooler on and you're sure everything is grounded it's tough to say.
