Hello everybody!
I am having a problem with my friend's PC. The computer wont turn on at all! I tried unplugging everything from the motherboard and putting it back, and nothing happened. Tried just with mobo, cpu and ram, but nothing happened. Oh I must mention that the original problem was that his monitor had no signal,or he couldnt see anyhing, but the computer turned on at first, but he opened up the computer and just unscrewed the mobo and screwed it back together, after that, it woulndt turn on. Thats when I came in! He took it to my house(since I'm a PC repair student) and I did all the stated above. I know the PSU is working fine. I'm guessing the motherboard is fried, since he did not use any protecttion when unscrewing the mobo. I think the problem was a static shock. I want to hear some other opinions before buying the motherboard. The mobo that I want is one just like the one the pc came with, I think I will have less problems if I do that. I also have another quiestion, will I have to reinstall windows after installing the new mobo?

Re: Help Please, computer wont turn on.

Well static can cause damage, but it rarely does.

Did you try taking the motherboard out and reseating it?
Look on the motherboard back panel to see if any of the tabs are bent over and maybe shorting something out.

Also, you say the psu is good. Did you check it with a volt meter?

Re: Help Please, computer wont turn on.

Yes, I've tried taking out the motherboard. And no I did not check the PSU with a volmeter but I did try with another computer and it worked. Woulndt it be easier just to change the motherboard?

Well if the psu works for sure, then I would double check the front panel power cables to make sure he put them back on right.

The motherboard being zapped out with static is just not likely. If it's dead, it probably was already dying when he started moving things around.

Re: Help Please, computer wont turn on.

He didnt unplugg any cables, he just unscrewed the mobo. So I guess i'l just change the mobo, and other question, will I have to do a clean install of Windows? Or will it just recognize the hard drive as normal and boot coorectly?

If you get the same model of motherboard, it will boot right up.

I would try to do the cardboard layout first though.

Re: Help Please, computer wont turn on.

I will try that. I tried already with cpu, and ram only. No video since it was the original problem, and the video card is on board. Do you think that's causing the prob?

Re: Help Please, computer wont turn on.

I did the cardboard layout thing, only with cpu and ram. The cpu fan spins for like 2 seconds and then it stops, any clue on what could it be?

Re: Help Please, computer wont turn on.

Well one thing that occurs to me is something that happened to me on two builds using the same model and brand of case, cpu and motherboard.

Brand new builds, but would only spool up for a second or two when you push the front panel power button.

Push the button, computer is starting, let go and the computer stalls.

I double and triple checked everything, and out of frustration I hit the power button 3 or 4 times, and then just held it in.. and the computer started up.

It did the exact same thing with both builds.

My best guess on the matter was that either the case company got a batch of power buttons that just weren't up to spec, or the motherboard company (in this instance, Intel) had a batch of faulty caps or something on the motherboard.

It's worth a try, and it won't hurt anything if you don't hold it in for more than 4 or 5 seconds.

Re: Help Please, computer wont turn on.

Well nothing has worked so far, i guess I'll just replace the motherboard with another just like the one it had and using the same cpu. And another question, will I have to do a clean install of Windows? Or will it boot up normally, since it will be the same mobo model?

Same motherboard chipset will bootup.

Good luck.
