428004 2006-02-07 11:08:00 Hi all

P4 3.0 Ghz Precott is MY CPU

I just got a NZXT Lexa case and it's excellent. But here is the problem.

First I couldn't figure out where to put thermal probe for the LCD temperature display for the CPU, so I put it between the heatsink and CPU. Then I connected everything and the computer refuses to start up and under the CPU column on the LCD display it says ERROR. All the fans are going but there's no activity in the Hdd and CPU, monitor stays blank.

I tried a couple of things like removing some fans and optical drives and no luck, I don't think it's the fans since I got a 480W PSU and it's plenty.

I prayed that my CPU isn't damaged and it wasn't, I transferred everything back to my old case and it was fine, computer booted successfully.

I'm just wondering if anyone could help me with the new case, why would it not start and how do I get a proper CPU temperature reading instead of Error, I don't care if I don't put that probe on the CPU anywhere is fine, just not the Error display.

Help very much appreciated.

Thanks 		michaelqian (9385)
428005 2006-02-07 11:25:00 Hmmm very interesting. Asus mobo's are known not to boot if they are shorting out on the bare case chassis metal. Only thing I can think of is to use those little browny/purpley coloured spaces that usually come with a mobo and place them between the mobo and the case mounting holes.

that may solve your problem, other than that I can't think of anything else really especially if the system works fine in another case.

cheers

428006 2006-02-07 11:26:00 Just tape it to the side of the heat sink and see if you can get it started in the new case.

The few CPU porbes I have fitted went under the CPU between the pins, not between the chip and heatsink. 		Rob99 (151)
428007 2006-02-07 11:31:00 Hi there, thanks for that. Didn't think of that. But still not sure what you exactly mean? The new case does not have those tall mounting holes just holes on the metal sheet if that's what you are suggesting. And the motherboard likes the tall mounting holes not the bare sheet?

Where could I get those things? A normal PC shop?

Because my old case does have those tall holes you screw on.

ALso my board is ASUS

The case is made of aluminium

much appreciated

cheers

PS. Any other possibilities? 		michaelqian (9385)
428008 2006-02-07 11:40:00 I found 6 mounting screws in the accesorry box the case came with, they have to be it, it fits perfectly in the case and will try installing it again first thing tomorrow.

Please keep other possibilies coming, so at least I would have something to try if it doesn't work tomorrow.

Cheers guys 		michaelqian (9385)
428009 2006-02-07 11:43:00 If your mother board was'nt properly mounted on the raisers I would sort that first before you go looking for trouble.

Dick Smith has small packs of computer screws, they normally have a good selection of screws as well as the small raisers.

or if that link goes dead http://www.dse.co.nz/ then search for XH5058 		Rob99 (151)
428010 2006-02-07 11:45:00 Please keep other possibilies coming,Power supply.

But I think when you have the board correctly mounted, and the probe in the right place it will work. 		Rob99 (151)
428011 2006-02-07 11:52:00 Kool thanks for that.

So basically the probe doesn't know if it's actually at the cpu or not. I can put it somewhere else and it will still display the temperature right? As long as my PC boots properly.

428012 2006-02-07 12:06:00 Yes, you could even leave it dangling if you wish.

The contact between the top of the CPU and the heatsink must not be interupted with anything, Artic Silver (www.arcticsilver.com) applied in a thin layer is all that should be there.

I am guessing the probe is a flat plastic like with a loop of very thin wire inside, you can carefullylay it flat on the underside of the CPU between the pins, make sure none of the pins get bent and it still goes into the socket nicely. 		Rob99 (151)
428013 2006-02-07 12:10:00 I would have never thought of the mounting screws if it wasn't mentioned. Also the thermal paste is pretty dry should I go and get some? I think that would be useful. michaelqian (9385)
