357230 2005-05-21 08:33:00 Building this new system for my cousin: P4 LGA775 3.4G, ASUS P5AD2-E Premium with 2 x 512 sumsung DDR2 RAM

Just completed the assembly of components and booted then entered BIOS setup. But the moment I go to Boot Priority, it shuts down by itself. Tried a couple of times, same problem.

Any suggestions, please

357231 2005-05-21 08:41:00 1: Check heatsink is on properly, you took the protective tape/plastic off it first off course.
2: Check heatsink fan is working.
3: Unplug/remove all components except ram, CPU and graphcs and see if it boots ok.
Then plug them back in one at a time.
Check IDE cables are orientated correctly, jumpers match the cable arrangements.
Check all components are seated properly. 		pctek (84)

Heat sink fan is working .

What protective tape/plastic you are referring to? I thought there isn't any protective covering for this CPU . I've built 3 P4s previously and they are all without any protective covering .

This is Seagate SATA 200 GB HDD and using a ASUS N6600GT PCI Express card .

Also, using Thermaltake VA3000BWA Case with 400 W PSU . There is 1 (single wire with a brown connector) yellow coloured wire from each of the case fans - one from the rear and the other from the front fan . I do not know what are they for (probably is a kind of sensing cable) and is not connected to the Motherboard . Secondly, there isn't any speaker (the tiny speaker attached to the Case) found but the user Manual says there is a speaker cable which supposed to be connected to the Motherboard .

Any clues at all?

357233 2005-05-21 09:31:00 Plugged out everything except the video card but still no joy.

I suspect those 2 yellow cables - what are they for? Could be a kind of sensing cable that sends the signal to the MB? 		bk T (215)
357234 2005-05-21 11:26:00 Replaced another PSU is it now working fine. Am now installing OS.

The cause of the shut down was because:

1. Faulty Powere Supply Unit;

2. That the 2 'yellow cable' is sending a signal to the system that the fans are not working and shuts down the system.

Does anyone know where to connect the two yellow cables so that I can rule out that the PSU itself is faulty?

Your help is much apprecialted.

357235 2005-05-21 23:25:00 Can anyone help me to trouble-shoot this problem?

Have sent an email to Thermaltake but won't expect an answer until Monday.

357236 2005-05-21 23:41:00 what problem? you fixed havn't you?

replaced PSU and its all working fine??

the "That the 2 'yellow cable' is sending a signal to the system that the fans are not working and shuts down the system" only applies to the cpu fan (in most cases) and i suspect your still running the same fan therefore its not the fan but the PSU .

tho sometimes you can get a fan which is a little slow in getting up to speed and the bios will shutdown the pc thinking the fan isn't working . 		tweak'e (69)

The tape on the heatsink not CPU .

As for the yellow wires:
From TTs website:
Q: I found a yellow and black wire coming from power supply, where should I have them connected and what is the function served?

It allows system to read fan RPM inside the power supply and should be connected to any CASE_FAN on m/b .

Don't worry about it, you don't need it, tuck it away somewhere . Nothing to do with your fault . 		pctek (84)

Thanks Tweak'e .

I replaced it with a another 350W PSU and the system is running OK . Now, my problem is: since this is a new case with the 400W psu, I should be able to return it for a replacement, right? Of course, I want to confirm that the PSU is faulty and not because I did not install it properly as I am concerned about the 2 wires which are not connected .

If it's because of the 2 yellows problem, then I am making a fool of myself by returning the PSU and ask for a replacement .

thanks pctek. but the TT site is talking about 'a yellow and black wire' com the power supply. In my case, there are ONE yellow wire each from the case fans.
