Open it up and see if you can re-seat the video card. That is, open the side, and push on the video card to see if you can push it in any more. Do the same with your RAM, cables, everything in the case. Just push to see if any of them are loose. Then close it back up and try hitting the power button now.

I've seen this problem a lot last time on HP machines and they are mostly caused by a faulty power supply. Turn it on and it turns off immediately.

Maybe one of your hardware crashed since you was updating your drivers. Do as hellnoire says and let us know what happens...

Sorry to know abt this..

Just check the power supply.

When u try to power it on, can u see/hear the fans running? Is there any LED glowing on powering it up?

It seems to be a low voltage problem , even if there is power .
check if this problem remain during non peek times ..
