Me And my bro are Building a new computer. It doesnt turn on. Do I need memory installed for it to turn on?

And right now we have the Harddrive, ATX Motherboard, Power Supply, Processor, CD Drive. And Wires that we thought was the problem.
oh and I think the Motherboard had somekind of graphics card built in. But any suggestions?

If this is wrong board sorry. if it is, someone make a link or tell me which board please. Thank you.

Hello and welcome to Techspot.

What do you mean by "won`t turn on"?

Normally if you try and start a computer without any ram, you will get lot`s of beeps.

A computer won`t post without ram.

I`m not sure what your problem may be.

Take a look at this guide to building a pc HERE (http://www.motherboards.org/articlesd/how-to-guides/924_1.html) maybe it will help.

You did use the standoffs between your mobo, and case didn`t you?

Double, and triple check everything.

I dont know. what does it look like? and do motherboards come with one?

I take it you mean standoffs?

They are the little spacers that screw into your case, and then the mobo is laid on top of these, and screwed down.

Take a look HERE (http://www.cfi1.com/standoffs.html) you`ll see what I mean.

it looks like my motherboard is just flat up against the side of the case.

Yes. They go between the mobo, and case. This stops the mobo from shorting out on the case.

Take a look at the guide to building a pc I linked to. It really is useful, and contains lot`s of good photographs.

Well if you didn`t use standoffs, then your mobo won`t work. All it will do is short circuit against the case.

Is that a common problem? and does it really mean the difference between a 450 powersupply or something like that from turning on the comp or not? just wondering. and how much do these cost? im taking some new parts and some old parts ( like the hard drive ) and putting them into a new case.

It is a common problem with first time builders.

If this is a brand new mobo, then it should`ve come with the standoffs in a small packet of screws etc.

If this is your old mobo from your old case. You can use the standoffs from your old case.

If you really need to buy standoffs. Any pc shop will stock them. They are only cheap.

Your powersupply has nothing to do with it. If your mobo is laid directly against the case, there will be a short circuit. All those solder joints on the underside of the mobo will be in contact with the case. Hence the need for standoffs.

well, when I look at my old case. Its hard to know if they are flat against the case. I dont know how big these standoffs are.

oh ok. well and is it possible that im trying to run it on a 150 watt? its a ATX-1523D PSU. when I have a 450 from a new case but i need like some kind of plug for it.

howard_hopkinso

I see what you mean about the psu now.

A 150 watt psu in all probability won`t be powerfull enough.

What plug do you require for the 450 watt psu?

Is it an adapter to connect the psu to the mobo? If so these are readily available from most pc shops, or the internet.

BTW, standoffs typically come with the case rather than the motherboard. Sometimes they're plastic.

Yes they should come with the case or the motherboard.

You are of course absolutely correct.

Why the hell I said they came with the mobo I don`t know lol

ok, when my bro came home he said he had standoffs on. another question. I had a 150 watt power supply for a new motherboard. woudl my computer turn on at all? I just ordred a 20 to 24 pin power cable so i can plug in my 450 watt. but would a 150 power up the computer at all? just wondering

That 150watt psu might not power on your system. Particularly if it`s a cheap and nasty one.

You`ll soon find out though when you try your 450watt psu.

well, its like 5 6 years old now.

In computing terms, that`s almost an antique lol.

A minimum of 350watts is required these days, with 450watts being the norm.

omg thank you so much. That makes me feel so much better. I sure hope I didnt fry the motherboard.

I hope your mobo is ok too.

Please let us know how it goes, when you get the 450watt psu up and running.

It won't turn on without memory.

It will turn on, but it will not POST.

If you have a too small powersupply the mainboard will turn off immediately; to prevent overloading the powersupply.

You might see the fans trying to spin just barley and the diodes (if there are any) briefly flash...

It actually is possible to run a systems like yours on a 150w powersupply, but it needs to be more modern, providing enough current on the +5v and +12v lines, many old powersupplies that are around 150w simply provide power at the wrong place, i.e. more than enough on +5v but not enough on +12v...

This would be an example (http://www.mini-box.com/s.nl/sc.8/category.13/it.A/id.417/.f) of a really small PSU that might be able to power your computer, note that I by no means mean that you should buy such a powersupply, they serve very specific purposes you are not in need of...

When you get the new powersupply double-check all spacers under the mainboard, i.e. that they are in all locations where there are holes in the mainboard, and that by mistake there is not any on any wrong places, i.e. where there is not a corresponding hole in the mainboard. Most mainboards has 9 screw holes, in 3 rows. Some have an extra hole between the PCI slots to the left, look out for this one for example...
