I am trying to figure out how to get my computer to turn on

Specs: Windows Vista, Windows Vista
How do I pull out and clean the ram. My gateway PC tower will not turn on. When you hit the power button the light blinks at you about six or seven times and then turns off. No fan no nothing seems to be turning on

Offhand I'd say the problem is either in the power supply or
the motherboard, or a connection between the two. Did you
poke around inside at all just before the problem began?

Yeah, it's not the ram that's doing that. If it was it would stay on and you'd get a ram error bios beep code.

Model number would be helpful, so would the exact number of power light flashes. Did you check the manual for the flash codes?

Might also be the on/off switch... Being very likely a mechanical type it can fail...

Agreed RAM issue is unlikely but as you asked here's a YouTube video:

Always pop back and let us know the outcome - thanks

Thanks for responding. No, my son went to go turn it on and it just wouldnt turn on. You hit the power button and the fans turn on briefly and then turn right back off while the power button just blinks at you. I have now taken out the ram sticks and blew out all the dust, made sure all the connections inside the tower were nice and tight and then put the ram sticks back in and it did the same thing. So then i tried switching around all the ram sticks and when i have one or two in slots 3 or 4 and hit the power button the two fans turn on like jet airplanes taking off. It still wont boot up or anything though

On the back of the computer where the power cord plugs in there may be a 115/230 voltage switch. If it's there make sure it's in the correct position. DON'T GUESS. If it needs to be switched do so only with the power cord removed.

Assuming that's not it, and there were no changes or damage to it, then it's the power supply or motherboard or both.

... or the switch - was the situation recently for another here I think... Switch mechanical failure isnt that coomon, but not unknown.

The component most likely to have failed is the one that is
most difficult to replace: the "son" unit. If he is at all like me,
he went poking around inside the case with the power on,
accidentally caused a short circuit on the motherboard, and
is too embarrassed to admit it. However, the component
"most likely" to fail often isn't actually the one that fails....

What does the voltage switch look like and how do i change the power supply and what exactly is the "switch"?

The "switch" is (usually) a mechanicl device behind the plastic push button which is what you push to power on/off?

In times past that switch was not physically mounted/attached to the motherboard, had a couple of wires that connected it to the motherboard.

Possibly it is a slghtly different arrangement today, but essentially the same idea.

Changing a power supply requires one that matches the one already installed; i.e. the same (preferably slghtly her) output. A psu is bolted into the desktop/towrr case, so can be be removed/replaced fairly easily. It will assorted cable which attach to assorted connection point on the motherboard; all clearly evident. But it's wise to make notes of what goes where; and perhaps even take a few pohotos too.

The voltage change mechanism can often be a wee plastic item accessed through a hole in the case, using a screwdriver to simply rotate it to the correct position. Many psu are auot-sensing, which means they detect what the incoming line/mains voltage is and adapts accordingly.

It would be very useful (wise) to get a copy of the (service) manual for the conputer, at the least the motherboard?

This is the voltage switch I was talking about:

It's going to be in the correct position unless someone messed with it and, as I mentioned above, don't guess.
