Northbridge heatsink flew off computer won't boot.

Hi, I recently took apart my pc to change the motherboard. As I was pulling out the motherboard from the case the heatsink from the Northbridge flew off, so I cliped it back on in the appropriate place and tried to put the pc back together. When I was finished making sure all the parts and peripherals are connected I closed the case and powered the pc on. As it started I heard the fans go on but no beep and the screen black.

Anyone?

I’d pull out the motherboard and place it on a flat, non-conductive surface, such as the motherboard box itself. Have only the following installed:

CPU
CPU Heatsink
1 stick of RAM
Video card, if nothing on-board
PSU

You can start up the motherboard by shorting the two pins for the power lead with a flatheaded screw driver.

Doing this will make it easier to troubleshoot and eliminate the possibility of a short happening inside the case.

Normally, a heatsink coming off shouldn’t be a problem. Now, if it scratched some traces on the motherboard, that could have issues.

Will do, although not sure which two pins you are reffering to?

That would have to be the the two pins that connect to your power on switch.

Yeah, powers on but still no boot signal and just like the power switch doesn’t turn the motherboard of for some reason got to turn of the switch on the Psu.

Yeah, still the same problem.

Well, if this is a new motherboard and the heatsink wasn’t secure, then I would get the thing replaced. It shouldn’t have popped off like that, so get in contact with the place you purchased it from about swapping you for a new board.

Ah, no not exactly I took apart the pc the night before the new motherboard came in and the next day missed shipping so I was putting it back up on the old motherboard. Everything seems to be working fine now, I’m on the xfx geforce 9300, not very happy with it though.
Lack of features and can’t set correct resolution after installing the graphic card on dual monitors. 1366*768 windows doesn’t show it as an option.

I tried some thermal greese, that didn’t do.

Were you trying to establish a connection?
