New PC not powering up

post #1 of 18
Thread Starter 
Hi,

I just put together a computer:

MOBO: Asus P5G41T-M LX
CPU: Intel Core 2 Duo E7600 3.06GHz
RAM: DDR3 Kingston HyperX KHX1333C7D3K2/4GX
Case: LC-Power 649BS Silver Black ATX
PSU: Power 420W

Every cable is in place, everything looks ok, when i press power button the cpu fan is spinning for half a second and stops, on the monitor nothing is displayed.
Where do you think the problem could be?

I tried disconnecting everything except for MOBO power and still the same problem.
I also put another PSU, Kraun 400W and no changes.
Please help me.

Did you try a different CPU cooler? You could try a different mobo to try and rule it out.

Hmm...I had close to the same problem before except my fans continued to spin. Make sure your RAM is in all the way. That fixed my problem with nothing showing up on the display.

Make sure none of the standoff's are shorting any thing on the mother board, and make sure the CPU cooler back plate is not shorting any thing on the back as well. Also swap Ram slots, try with one stick then the other. If that doesn't work try running case less on a piece of card board/wood.

CPU cooler? And mobo should be the last thing to rule out...

Sounds like a seating issue to me. Make sure your video card is fully seated and has all power cables connected. Next make sure RAM is correctly installed. Are you getting any beeps when powering it on?

I will try the PSU on another system to see if it works.

OK, the PSU works on another system.

I don`t have any video cards, i`m using the built`in one, i tried using only one RAM and still the same problem.

Ok, strange thing happened. I pulled out of the case the mobo and tried powering up and it works. How come?
