PC won't turn on

TechnoComputo · August 20th, 2008, 03:55 AM

Hello to everyone I'm new to the forum so I'd like to introduce myself my saying hello. I have a serious computer issue but then I'm sure that's why we're all here, right

. My computer will not boot up for some strange odd reason. When plugged in all the fans turn but the power nor the reset button will turn it off. I can only get it to turn off by either using the main power switch in the back or just unplugging it. Don't have any testing tools to determine what the problem could be. I'm using a Asus motherboard with WinXP but forgive for not knowing the model# at this time. I've been using this computer form my music studio and all I have connect to it is a US-122 sound card, which is USB connected along with a computer sound system. I haven't tried troubleshooting the problem because I don't know where to start to completely honest. Could anyone please help me with my dilemma. It's greatly appreciated. Thnx in advance...

Just to help us understand the problem, the computer was working correctly and now its not? Have you made any hardware changes, moved the pc or done anything else with it prior to it quitting?

None at all. I was using the computer at one point, left it on for several hours and when I got back to it found it in that condition and it's been that way every since. I really can't explain it but I've never had any problems before. I have to say that it really boggles my mind.

Well if it was running and you left it on then came back to this mess its very likely that something fried. Does it smell like burnt electronics? Open up the case and look over the motherboard for any discoloration. From there its going to be a process of elimination on troubleshooting.

Do you get any beeps or anything? Have you opened the case to make sure all your fans are still spinning? When you power it on do you hear the hard drive making any noise?

I called myself checking for anything that may have looked burnt when I opened it. All the cooling fans are blowing even on the power supply and processor. All the fans turn on/off when I turn the power supply off from the main switch in the back and all LED lights work even the power light on the motherboard lights up as long as it has power but there are no peeps. And no I don't hear any noise coming from the hard drive when the power is on. The only thing that is visible to the eye are the cooling fans spinning and the power LED lights on the motherboard and fans and the fans are the only thing I hear.

Now you're telling me at this point it's a process of elimination but my question is where do I start and what do I eliminate first.

I would start with your power supply. Do you have another one lying around that you can swap with? Also was this computer one that you put together or something you bought? If so what series computer is it (i.e. Dell Dimension 2400)

It's a computer that was built by my cousin and given to me as a loaner. Now you're telling me to start with the power supply but I mentioned twice that the power supply cooling fans are spinning but even though they are you're telling me that it still can be defective? I've had a power supply go out on me in one of my other computers but it was a simple visual solution because it burnt up. But this is nowhere near a concurring problem unless the problem is internal because the cooling fans on it still work. So to answer your question about the power supply, no I don't have anymore laying around.

The Power Supply seems to not supplying enough voltage/current to the rest of the system in order for the computer to boot. I would suggest getting a new one.
Edit- While this Power Supply would probably be overkill, it is very good for the price.

I can't wait for it to come in today!

Thanks for the advice. It's truly greatly appreciated. But I do have one concern about what you said regarding your comment about it though. Being that it could be overkill could that burn out something else by applying too much voltage/current? Or is it that you can never have too much power?

**RicheemxX** · August 20th, 2008, 02:28 PM

There really is no such thing as overkill when it comes to power supplies, the system will only draw as much power as needed. Trying a new power supply is probably the best place to start, even though it powers on the small things like the lights, fans ect it might not be pumping out enough power for everything else.
