Advice - Machine boots then switches off

Hi

First post, be kind :-)

Just bought a load of components from OC. Put everything toghether yesterday, everything worked fine.

Today, I start the machine up, it gets as far as loading windows, then shutsdown. I removed the connectors from the SATA drives I have, went into the BIOS diag, wait 5 secs and the machine shuts down within 10 secs.

I get no error message. I leave the machine 1/2 hour to see if it's an overheating problem (all the fans are working fine) and the same issue re-occurs, hence I don't think it's a heat problem as it happens very quickly.

I'm a bit confused...

Bits bought were:
HSI X1900XT
Conroe 6600
Asus P5B Delux (which I had to flash as it gave an error about the Conroe - uCore issue or something)
2X1Gig Cosair 6400C
2Xseagate barracuda 250G

I'm suspecting the CPU is goosed? I don't really want to return the whole lot to OC, but there's a problem somewhere which I suspect is the CPU but I can't test thing given the damn thing won't boot!!!

Is it overclocked at all?

What PSU are you using?

Probably PSU related if it's not overclocked.

Nope - overthing is standard. I've got a Ezcool 600W PSU. After I upgraded everything, my old PSU (Antec 380W Trueblue) didn't have the correct connectors, so I rushed out to a local geekshop and got the Ezcool for £45 just to get up and running....

You reckon the PSU then? Any way I can prove this? If I remove the PSU from the motherboard, how do I power up the PSU standalone to see if it;s that which is switching itself off after 10 seconds?

not necessarily the PSU switching itself off, more its overloaded and shutsdown to prevent it going boom. EZcool isn't a brand I've ever heard of. Never scrimp on a PSU, you will learn that pretty quickly. Get yourself something like the Tagan modular 530W. I know its about £75, but well worth it.

Think about it like this, if you've spent £1000 on a PC, why would you spend £20 on a PSU? afterall, you will want something that can power the whole thing reliably.

Not disagreeing, BUT as standard PSU surely should be able to power (nothing overclocked) Conroe 6600, X1900XT and 2 SATA drives? It's 600W!! It has no problem powering everything the 1st day - it's only today that my blinking machine has started thinking that only booting 1/2 through is good enough :-(

What it says on it doesn't necessarily mean a whole lot.. there is a vast difference between Enermax 620W and FredBloggs 620W. Not trying to be elitist, it's just fact

There's a reason it costs £45 when the other ones cost £90+....

I reckon its the PSU myself, the X1900 alone will eat power.

The only time I've had mine shutting down spontaneously is when I've overclocked it too much (I'm using a FSP Epsilon 700W).

Hi

Finally got this sorted. The CPU cooler had become loose and the CPU was overheating and switching itself off. Applied some new silver thermal compound and attached the cooler correctly and hey presto!

Thanks,

Just read your post and was going to suggest is was cpu cooling related. My Athlon 64 system started displaying the exact same problem a while back after i had opened it up to clean out the dust. Turned out my power cable had blocked the fan on my Zalman 7000 so the cpu was getting hot very quickly.
As for the psu advice, a good one can be the difference between the pc running smoothly and giving untold issues. But if it works and you have had it for a while then, you know it best. The more expensive ones are worth thier monet though, I have a Hiper 480, not that long ago Hiper was the make to get but not anymore. :confused:
