Hi everyone,

I would sincerely appreciate any help with my problem. I will try to describe the problem and steps I took to fix the computer as closely as I can. I hope that doesn't bore you. If there is anything I said that is inappropriate, please accept my apology.

I I built a system using the following components during the weekend after the Thanksgiving week (literally on December 1, 2007).

ASUS M2N32-SLI Deluxe Wireless Edition AM2 NVIDIA nForce 590 SLI MCP ATX AMD Motherboard
AMD Athlon 64 X2 6400+ Windsor 3.2GHz Socket AM2 Processor Model ADX6400CZWOF
Antec Nine Hundred Black Steel ATX Mid Tower Computer Case
Rosewill Stallion Series RD500-2DB ATX V2.2 500W Power Supply
Zalman CNPS9700LED Ultra Quiet CPU Cooler
Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model BL2KIT12864AA804 (4-4-4-12 2.2Volts)
OCZ 2GB ( 2 X 1GB ) Platinum PC2-6400 800MHz 240-pin DDR2 Memory - OCZ2P800R22GK (CL 4-4-4-15, 1.9 - 2.0 Volts)
XFX PVT84GUDF3 GeForce 8600GTS 256MB 128-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card

Rosewill RCR-102 52-in-1 USB 2.0 Black Card Reader - Retail
Arctic Silver 5



I can only honestly said that I have witnessed the system working beautifully for about ONE hour. After I put the component togethers, installed Windows XP, I put the assembled computer back into the Antec 900 box and readied it to be shipped back to China (I currently live in China so I took my thanksgiving holidays in the US, bought the computer parts and built the system) as a check-in baggage when I go back to China on December 6.

Fighting the jetlag, I opened the box, took out the computer, SWITCH THE POWER SUPPLY UNIT TO THE MARKER THAT SAYS 230 VOLT (unlike in the US using 120V, China uses 220V), connected to monitor, turnred on the beautiful computer, all the fans and blue lights from the case, PSU and Zaleman HS were all working, but NOTHING on the screen.

My immediately reaction was something came loose during the flight. So I opened the computer case and found the 1934 connector was loose, but thought that was not the problem. I searched the internet and found suggestion that said I should clear the CMOS (RTC RAM). So I did that, no luck. I then began to take out the memory sticks and re-seated them and that didn't work. Then I left only two sticks of the Crucial Ballistics, still didn't work. So I tried to remove the retention bracket that locked the Zaleman HS to the retention module base (the black retangular rail surrounding the AM2 socket). This was very difficult to do. So I unscrewed the retention module base, and the Zaleman and CPU poped out very easiy. Then I removed the CPU from heatsink and re-seated back to the socket and reattached the heatsink. Turned on the computer, this time, the PC turned on for about 5 seconds and then everything shut down by itself.

So, now I am stuck with a PC that won't boot at all. I saw some post that it might be the motherboard and some post said that it might be the PSU. Since I don't have any spare part here, what can I do to further diagnose the problem?

Does anyone have any idea what other problems could be? I would be very grateful for any help.

zoro1,

I would consider taking the whole thing apart and start from scratch. It's possible something got jumbled during the shipment to China... check especially under the motherboard to make sure none of the standoffs loosened and came off and are running around free, maybe causing a short. You can disassemble the entire thing in an hour or so and rebuild it in an hour or so and then know everything is correctly situated. I think that beats hit and miss trouble shooting.

Before rebuilding, check out some essentials... put the motherboard on a static free bag or a piece of cardboard. Then add the cleaned-off CPU, re-paste it, add the Zalman (be sure to hook the fan to CPU fan header on mobo) , put in one stick of memory only, then the GPU and hook up the power supply to the mobo (24 pin and 8 pin and GPU power, too. Turn on the power switch and It should post for you (you may need to hook up the case power button to the block on the mobo to get the power to the circuits. If it doesn't post, switch the stick of memory for another. If it still doesn't post, you have either a mobo or PSU problem. You can check PSU by using a different PSU if you can get a hold of one... If the PSU works, RMA the mobo... Now if the board posts, put the motherboard in the case on solid standoffs, and re-build the entire rig again. You should have a working computer now.

BTW, not sure I would use 2 different kinds of RAM... that could cause you a problem with different timings, different voltage requirements, etc... Besides, you really only need one good set of 2GB to get good ops out of your computer...

Good luck, let us know how it goes, Noel

Hi NoelS,

I was just thinking that when worse comes to worst, I will take the whole PC aparts and start scratch. So what I did this morning was removing all the RAM and just put one stick in, and removed the CPU and Zalman again and reseated them. And what a surprise. The PC POSTed and booted into Windows. I was quite delighted!

Not sure why it didn't work before.

Or, maybe it was working all along the first time I turned on my computer after arriving in China. I just didn't wait long enough for the POST to appear thinking that I would fry the MB/CPU. Oh well.. I am happy except that I do have a new problem:

After I shut down XP, the computer refuse to shut down. What I mean by this is that all the fans, and power remain on. I can tell XP is shut down properly because the monitor said no signal. However, all other mechanical part just continue to run.... not sure why...

I think I will ask a Asus Tech Support... or if you or anyone has any tip, please let me know as well. Thanks in advanced!

Hi etech,

yes, that was the first thing I did, switch to 230V marker on the power supply before I powered on the computer in China for the first time.

By the way, the computer is working fine now.. except after I shut down XP, the rest of the computer won't shut down (see my post above)... weird..

Thanks for your reply

zoro1,

Glad you got it working. Look at your case's wires that are used for the HDD LED, power, etc., and make sure they are ALL properly connected and the polarity is also correct (colored wires are positive, white is negative). Check your mobo manual for the polarities. Also, you may be getting a short in the power switch, which keeps the board powered after you shut down. You could also check your case's power (start) button and make sure it's not sticking when you turn the computer on.

BTW, are you using all 4 sticks of RAM that you have listed? Just interested how that's working...

Noel

Hi Noels,

Thanks a lot for the tip, I will check it out when I get a chance this coming weekend. For now, I just manually switch off the PSU using the switch in the back.

For the RAM, I am using all the slots with 4 sticks. They seem not to give me any problem. Of course, I have not tried OCing anything yet. I don't think I will do any in the foreseeable future :)

Again, appreciate your help.
