Hi there!
I have a problem with a "pcchips m729" mainboard!
Yesterday the computer worked quite normal!In the evening I shutted it down and the next day when I wanted to start it,it happened nothing!
No "beep", no sounds of working, no lightning Num-Lock LED on the Keyboard... Only the CPU fan worked! Then i flashed the Bios with the latest update (Another Computer, Uniflash, ignored the warning)
But theres still nothing. In my opinion the Bioschip is broken or something, but I don´t have presentiment where I can get a other one...

Thanks in advance for your suggests.
Cu, damdp

Have you checked that the cards are properly inserted, memory properly seated in its sockets, etc ?
Have you checked the CMOS battery voltage ? Some boards will not boot with a dead battery.
Also, I can recommend the "PC-Chips Lottery" forums at http://go.to/th2 (watch out for the pop-ups)

Now I´ve checked the cards,RAM,CPU and Cmos batterie but there´s still nothing...
I´ve started the Computer with a VGA card and Cmos batterie but without CPU and RAM and the there was quite the same like before...
But thanks for the link to the Pcchips lotterie! I´ve posted my problem there too...

I suspect an electrical surge went through and killed the mainboard.

Tried another power supply?

Grab a voltmeter and measure the DC voltage from ground to the DRAIN terminal of the MOSFET which supplies power to the processor. It should read between 1.65V to 2.2V depending on your processor.

If no reading at all, then the VRM (voltage regulator module) has died and there's no way your processor could come alive without Vcore, unless you know how to replace bad capacitors.

If there is power delivered to the processor and the voltage reading matches your processor's voltage rating, then chances are very high that your processor is still alive and so we can talk about your BIOS then.

Sorry if this sounds too technical for you, but it eliminates guesswork when troubleshooting the mobo.
