I think I screwed up my system, need help

[nigeln]

I was shutting down my computer with windows 7 and it was downloading some updates, then it shut down. After the shut down, I was trying to clear any power left in the system my turning off the power supply and pressing the power button but I forgot the turn off the power supply and I started the computer, then I immediately shut down the computer. It did get to any boot screen. I turn back on the computer and it would not boot. The light on the monitor did not indicate any signal and the hard drive indicator lit up and then went off. Now the computer will not even boot into the bios. I remove the cmos battery and put it back in to reset the bios but not luck. I do not have a recovery CD since this is a pre-build system by HP. Need help asap!

Do you get/ have you ever gotten any POST beeps? When you hit the power button now do the fans spin up or does the whole computer stay motionless? Turning off your computer wont usually kill it but on rare occasions it may fry your motherboard. Also, might be a long shot but is there a chance your monitor is not acting right or your forgot to switch the PSU back on?

I have no idea what you were trying to do with your power button .

But it sounds like you have either 1/ damaged the power button itself , or 2/ damaged the power supply

The power supply is working, all fan are spinning, HDD is spinning. I think the problem is with the HDD, the HDD light comes on and then after a few seconds goes off. I might have screwed up the OS when I shut down after the initial restart. I cannot even boot into the BIOS by pressing F8.

Sounds more like you may have a dead motherboard. Try taking out all unessential things in the computer like a second stick of ram, video card, you can even take out your HDD, oh yeah and for sure the disk tray. Once you have all of those things safely unplugged you can try to restart the system and you shouldn't even have to press F8 since there is no boot device. If you still have nothing you can try to clear the CMOS but at that point you really know you have a dead motherboard

I removed the video card and ram. I then put in one 4gig ram stick in the first ram slot and I got 4 beeps and a pause then 4 beeps and a pause again. ram slot 2 I got no beeps, ram slot 3 I got the same 4 beeps and a pause, ram slot 4 no pause. I also plug back in the video card when I had the ram in slot 2 and 4 but I got no signal to the monitor. So it looks like the mother went bad. I went on eBay to see if I could purchase the same motherboard but it was $124, i am sure I can purchase a better motherboard for less. I do have a copy of window 8 pro so I would not have to buy an OS.

Well actually the fact that you got beeps is a great sign. I'm not familiar with HP beep codes, and they are a little different for every board. Google the board name with beep codes to find out what your beep code means exactly. You also unplugged the HDD and disk tray if you have one? You may be able to just clear your CMOS which is a fairly simple process on the board itself.
