New Build Randomly Shuts Off After 30 Seconds?

Put together a new system yesterday Core 2 Duo 6300, Asus P5n32-SLI, 1GB Geil Value DDR2. Theres two problems really.

Firstly 75% of the time when I turn the computer on it blows the switches (problem 1).

Secondly at first the computer wasn't giving out display so I took it all out of the case then stripped it down to the CPU (+Heatsink) + Memory + Graphics Card. Still wasn't getting output to the monitor so I removed one of the memory sticks and it booted up giving display to the monitor, swapped sticks around and it seems its both cards work providing theres only one card in the mobo (Problem 2a).

The other problem is that even when it does turn on, wether you leave it idle or go into the BIOS etc the computer shuts off after around 30 seconds but the motherboard light stays on (problem 2b).

This caused yet another problem (how depressing!) when I decided it would be a good idea to change something in the BIOS then as it was saving and exiting the power went, now when it powers up the heatsink doesn't spin, or give any output to the monitor (problem 2c).

Anyone got any ideas? Got no idea what to do!
Cheers.

What do you mean by 'it blows the switches'?

The mobo powering down that quickly would indicate a possible power or CPU fan not plugged in issue. (And a few other things)

The power went off as it was saving the BIOS. :(
Not good.
Tried re-setting the CMOS?
It SHOULD only be the configuration options part of the BIOS chip that has been corupted by that.
 
If 'blowing the switches' is the fuses/circuit breakers in the house tripping - Something is wired up wrong and is a direct short! :eek:

Strip case down and re-build up.
Only have PSU + mobo in to begin with.
Then add components.

I wouldnt be trying to get the system working till this problem is solved first.

Like the others, it would be helpful if you clear what you mean by this, as its likely an important factor to the problems.
 
Sorry guys, I meant it was knocking the fuses off.

I've tried resetting the CMOS, with no luck the heatsink still wont budge.

I'll try rebuilding it from the cpu + mobo up and see how that goes.

The first thing I would say is you have a direct short somewhere in that machine.
Strip everything out, check cables, see what could be causing it.
Try the PSU separately etc.

It may be that you have already fried something TBH.

Tried a different 13A socket?
(IE, where the PSU plugs into)
 
If you're tripping a fuse that often its the source a problem i'd think, psu, kettle lead, plug at the wall etc.....

Like said, you could have blown something already.
 
eeeek thats pretty nasty if its tripping everything, get it sorted asap could cause your PC some damage, check PSU wires/fuse/lead etc firstly!
 
Maybe take the components out of the case and try it that way.
Just Mobo,CPU,Ram,graphics and PSU

then short the power pins with a bit of metal to get it to boot.
 
Just stripped it down to Mobo/CPU+Heatsink. Fuses still going :mad:

I've double checked all the connections from the PSU> Motherboard and I'm pretty sure they're all correct and plugged in firmly (24(20+4 Add On) +8Pin).

The PSU when it's not plugged into the motherboard turns on fine without blowing the fuses but I dont really understand the mechanics of one, maybe theres just no power going through it :p

I could try the PSU on my old AMD1800+ but that would only need the 20 pin with no 4/8pin for the CPU so I'm not sure if it would be much use.
 
Scrap that just tried the PSU again when it's plugged in to nothing and it's still popping the fuses. RMA time?

I scratched the PSU abit when putting it in the case (it's black) there any chance they'll refuse it? (gotta check ;) )

Cheers.
 
can rma it so long as its minor cosmetic, IE the scratch hasnt somehow ripped thru the casing and broken something :p especially as it hasnt worked since youv'e got it

The product is faulty...
They should not refuse an RMA for a scratch.

Mind you - Antec don't even ask for the old one back. 0_o
 
You got another PSU you can borrow in the mean time to test the other components with?......

Its worth checking to make sure the PSU hasnt done any damage to the other parts, just incase.
 
Is it a 'fuse' that is 'blowing' or is it the main switch which may well be an RCD and not a fuse at all?

Either way, something is shorting somewhere.
 
It was a little fuse switch in my uni room, I've just taken in back to my parents house and it's not knocking the fuses off there. Guess it's a problem with my room.

I'm going to bring all the comp back to my parents house later and try build it up and see if the outcomes any differant.
 
Ok an update guys, I've taken it all home and rebuilt it there the fuses aern't going so that must just be a problem with my uni room (awkward).

Even with just the mobo + cpu the heatsink isn't spinning. RMA the mobo? Hopefully it isnt the CPU I've busted, but I'm thinking it's the mobo with the power going when saving/exiting the bios and all. With no luck resetting the CMOS I'm lost!
