Not starting up...

[sean1983uk]

Recently bought a new case and transfered all my parts over and connected up the power/reset/hd led and power led wires waiting to be impressed by the case. Closed it all up, plugged in power supply, and touched the sensitouch button to power it up...

NOTHING!!!! well it starts up then after about 3 seconds turns off!

I've tried connecting the wires round the other way etc, but still does the same.

If i just have the power wire connected it will start up and laod windows, but when i close down i then have to turn off at the power supply for about 10 secs before i can turn it back on again.

I thought it might be dodgy wires in the case so tried it on my other computer and it all works fine.. so i'm thinking its something wrong with my motherboard?

I was worried i'd ruined it some how so put it all back in its old case connected it up and it works fine.

So its just not working in the new case for some reason :(

The case i have is:

this is my motherboard:

i've tried connecting it when its not in the case, incase the case was shorting out somewhere but still wont load up.

Think i've covered everything, if not just ask

So anyone have any Ideas?

Sean

just an idea but whats the "Case open detection header" could this be doing it? or would it not even load up once if this was teh problem?

Ok.. When you press the button the first time it worked for 3 seconds and it stopped, and now it doesn't work at all anymore? is that what you're saying? if so it's you're power supply..

If it works fine in the old case, then it is not any of the hardware.

I would bet you missed a connector or wire when installing it in the new case. Try again, but double, and triple check each and every wire and connector.

Write down each one as you unplug it in the old case, then cross it off the list when you go to the new case.

[sean1983uk]

no the first time it will load up, its only after i shut down that it wont start again.

i've tried it with another powerpack to and same thing happens..

anymore ideas?

[sean1983uk]

hi sterling,

tried that too everything is def connected it just doesn't make sense to me :s

[foress_89]

Try it again in the old case, if it works there, it's something that's not connected properly. Are you sure the case connectors are plugged correctly in the mobo?

[Midknyte]

are you sure there aren't any extra standoffs under the board in the new case?

[sean1983uk]

I've tried the connecters in each way round, starting with just one and adding more. Still nothing.

is it possible the mothervoard doesn't support it?

[sean1983uk]

what are standoffs? sorry

[foress_89]

places to screw the motherboard I think.. it make sures everything is grounded right. right?

[Midknyte]

standoffs are the mount points under the motherboard. they are usually made of brass. the fact that you didn't know what they are concerns me.

[sean1983uk]

i know what they are didn't know they were called that. i got six of them all in place, that should be enough?

[Midknyte]

they should be placed under the ISOLATED holes, aka the holes with the grounded rings around them.

[sean1983uk]

yup thats right, the mobo and everything else works in another case fine

[missiveusa]

i know what they are didn't know they were called that. i got six of them all in place, that should be enough?

Six standoffs for an ATX motherboard? Not likely. Use the correct threaded screws for ALL the standoffs. ATX board will have at least 9. If you're not installing all the brass standoffs in the case, the board will short out.

[Sterling_Aug]

I also use the old nylon standoffs that I have collected over the years. They seem to be better isolators than the brass ones.

Check to make sure there are no extra places in the case that could cause a short.

[sean1983uk]

at the moment i have the motherboard in another case and it all runs fine, i'm using it at the moment to post this.

How ever when i connect the wires from the other front panel (leaving it all in this case) it will not work, so its def not my hardware or mobo shorting out.

any other ideas?

[Sterling_Aug]

It sounds like a short in the new case or a bad power supply in the new case then.

[sean1983uk]

Hi Sterling,

i dont think its that beacuse the only thing i'm doing is unplugging the case wires in old computer and plugging in the wires from new front panel. not actually taking anything out of case in which it works fine.

[Sterling_Aug]

Then you have a bad switch in the new case. Try plugging the reset button wire into the power button connection on the mobo, then try turning on the PC using the reset switch. This will tell you if you have a bad power on switch.

[foress_89]

I had a very similar problem with my lil brother's computer. The power switch get stucks, so you have to remove the front panel and unstuck it. It looks like a small issue, but it's not the first thing you think about when the computer won't start..

[Rocketmech]

You can also isolate the switch as the problem by using a flat tip screw driver or a ball point pen and momentarily touch the power switch pins on the motherboard to power on .

[sean1983uk]

yeh i tried that with screw driver it loads up fine..

i did think it was the switch problem myself, but seeing as it works fine on another motherboard/computer setup then i'm starting to wonder if its the motherboard some how?

[rmanet]

first off, I'm with Sterling - love those nylon standoffs - never have grounding issues when I use 'em

you have one problem or the other - mobo isn't grounded properly and/or it's always a problem using the new case connector wires, the case switch(es) and/or hooking up your case wires to the mobo - when switching cases I always take both cases - put them side by side, and carefully move one connector at a time.

recheck everything and carefully make sure you connect the case connectors properly - if you need to use the mobo manual (d/l from the site if you don't have it) and/or whatever is silk-screened on the mobo - lot's of times I've found them to be contradictory :rolleyes:

be consistent in watching what are + and - posts on that strip of pins as well as they relate to the wires

for use everytime you turn it on be sure, you have your psu and cpu fans running - sometime only takes moments to fry a cpu

and if you think it's the case switch quit screwing around and return it for another.

good luck, get a new case start over and carefully compare the connectors in your old case to the new one and try again - like everyone else I don't think you have a problem with any hardware or your psu or mobo

I have a similar problem on an ASUS k8n-vm. The system powers on for 3 secs then shuts off. I have used the screwdriver trick. All screws are attached except for one, no hole, also I have a mboard mounted on a piece of plywood with no problems. I have swapped around PSUs no change. I have disconnected everything and tried to power up, no change. I have swapped in different mem sticks, no change. Only when I take out all mem sticks will the system stay running, of course nothing boots, just sits there and beeps.

Seem to be drawing a blank here.

I think you should start your own thread . Meantime , test outside the case again with only the cpu w/hsf , 1 stick of ram , video, monitor and keyboard . Try to access the bios setup . See your mobo manual on how to access the bios setup . If you can get video and access the bios setup , then your having a case grounding issue , either from the mobo standoffs , backplate openings or case switch .
