power supply or fan?

My pc stopped working yesterday. When I pulled the power cord out and plugged it back in and press the start button the fan bumps, then nothing. Could it be the fan tripping a circuit breaker or bad power supply?

What circuit breaker? What's the make, model & OS, of the PC? If it's an old desktop, there is a good chance that the power supply is bad.

Thanks pulpo, I have no idea if there is circuit breaker or not in the power supply. It's Acer m# aspire x1700. It's a vista 2008.

Are we talking about a desktop or a laptop? I see that Aspire can be either.

The fans run on low voltage from the power supply. That momentary blip in the fan is telling you that the power supply is starting for an instant and then failing or going into shutdown.

I see the same thing Pulpo sees that this can be either a desktop or a laptop. If it is the desktop from what I saw of it when I looked it up it looks like the power supply may not be a standard power supply so that may have to be ordered from Acer. For the laptop not so much of a problem as you could even buy a generic no brand and it probably would work fine. I am thinking from what you have said so far that this may be the desktop as you haven't mentioned trying this on battery power. Having pictures of the power supply will be helpful then we can tell if it is standard or not.

Please describe any markings you see on the power supply too. Some manufacturers have always used standard parts and some do not.

Sorry, but my opinion is that a seven year old Acer is better replaced than fixed.

I would take a chance on a power supply.

The chance of the PSU failing is higher than the fan failing.

The chance of the PSU failing and preventing the computer from turning on, is higher than the fan failing.

I have only experienced fan problems when they are first put in. Either they work or they don't but from the years of experience, I have never seen a fan preventing a computer from turning on.


Just my basic analysis:
PSU fail, nothing turns on.
RAM fail, computer turns on and may keep rebooting.
Graphic Card fail, no display. Could also be caused by PSU too.
Hard Drive fail, everything turns on but before attempt loading operating system, it will say that OS is missing.
Motherboard fail, well this is a tricky one to determine.

Out of the above list, I would say PSU has been more common for me than any other hardware.
