HP m7680n won't turn on. [ Edited ]

[Bware]

Hey all,

My computer has been on for a few days, and I like to shut it down every now and then to give it a break.  I shut it down and went out to eat.

Upon coming back, I tried turning the computer back on, only to find out that it won't turn on. Pushing the button on the front does absolutely nothing.  Nothing lights up, no fans start, nothing.

The computer was working just fine before, and I even restarted it after an update 2 or 3 days ago. The computer shut down without any problem, it just doesn't seem to want to turn back on...  I don't think it's the cord (I plugged it into my monitor and the monitor turned on), and the green light on the back of the power supply is on when it's plugged in (the light is steady, not blinking).  I tried changing the CR2032 battery on the motherboard, but that didn't work.

Any suggestions?

Thank you!

Unplug the p.c. and then remove and reseat the memory,video card,cables,etc. Turn it back on and see what happens. I nothing works it could still be the power supply,power button, or even the motherboard.

Thanks, I'll try reseating everything.

 If that doesn't work though, is there a way I can test to see if it's the motherboard, power supply, or power button?  I only want to replace what needs to be.

How would I replace the power button anyway? I've never heard of that failing.

It could be one of those things mentioned. Does the power button feel like there's tension on it? Does it click or sound as if it's engaging?

That was really just a possibility.

I replaced the power supply and now it's up and running.  Strange, I didn't think a 2 year old computer would blow out a PSU, especially when I haven't added any hardware to it.

Thanks for the help!

Great to hear. What brand did you use? That info will help others.

I was going to go with a Corsair 550w from newegg, but I couldn't wait, I needed to get everything running tonight.  Bestbuy was the only place near me that was still open, so I went for a BFG 450w.  I know they make decent graphics cards, so hopefully the same quality goes into their PSUs.  It's a little larger than the one that came in my HP, but with a little finesse (cramming) it got in there.

was the power supply hard to replace?
