Another Non-Booting Computer

By mordacity ·
I bought a barebones kit with
http://support.intel.com/support/motherboards/desktop/d101ggc/
this mobo. I got everything connected and it was running fine for a couple of hours (long enough to install Windows, network it with my other desktop, and play a little Lineage II). Then it just died. The monitor lost signal (amber power light) and that was that. The computer won't boot back up (when I hit power on the PSU, the LED on the mobo comes on, but after I hit the soft switch on the front, no POST beeps, although the LEDs on the keyboard blink once, and the CPU fan comes on). I've tested the monitor, and it's dead now (not surprising, it's an older CRT). But when I connect a working monitor, still no signal. If I set the BIOS jumpers to 'Recovery' and boot up, the (working) monitor gets signal, but the BIOS shows an error and I just get continuous beeps. Any other jumper settings, and I get nothing. I've wiggled the RAM around, reseated the chip and heatsink, removed the CMOS battery for 10 minutes and put it back in. I've unhooked the HDD and CDROM (so it's a bare boot - just mobo, processor, cpu fan, RAM and power supply) and still nothing. Any other ideas before I go through the long and irritating process of trying to exchange the mobo?

With Intel boards the recovery jumber setting is for when the BIOS gets smoked and you can not load the PC. What you need to do to recover your bios now is create a blank formatted floppy download the recovery bios from Intel's website and place the .bio file on the diskette. Turn off the machine and then insert the diskette. Change the jumpers to recovery, then power on the machine. The machine will have a progressing beeping sound in tone. when the machine powers off, remove the diskette, and set the jumpers back.
Good Luck.

I appreciate the heads up on the intel bios recovery, I'm sure that's information that will aid me at some point, but when I tried it I got an error that it was unable to read from drive A, but it turned out to not be a bios problem anyway. That'll be a troubleshooting project for another day.

Abad power supply may be the culprit,make sure you have all jumpers to the motherboard secured properly.
If you possess a volt meter tying testing the
voltage
Check the cpu and other fans to see if they are working properly system could have over heated

It was indeed the power supply. I was skeptical about swapping the power supply (the one that blew was a brand new antec), which is kind of ironic, I usually go for the power supply first (in fact, embarassingly, once changed a power supply on a computer that just had a bad power cable). But before I came back and rated this unacceptable I thought I should at least try it. Lo and behold..

It sure sounds like a power supply, check all voltages Otherwise the continous beeping is
the memory failing to load even the bios into
the starting memory block. With a loading
properly, the first display you see should
be the video BIOS and how much memory it has.

See response to the other helpful person that suggested the power supply. That was it. Thanks!

Did u use the spacers when u mounted the mobo? wondering if one of the joints hit the case. When you say "It just died" was it on and running or shutdown? Is everything new or did u recycle parts (mem, power supply etc..)

Did use spacers, everything new except the CD-ROM, and it was running and shut itself off. Solved the problem though (it was the power supply).

Well as you are getting no display and you have not described the Beep Code it's a bit hard to say but from your description I would say that the Heatsink was not fitted properly and the CPU has Fried.

Remove the Heatsink by twisting the slots on the heat Sing through 90 degres and they should release and look at the top of the CPU for Heat Sink Compond to see if there is an even spread of the compond over the CPU. If there isn't the Heatsink was sitting off the CPU and has allowed it to overheat and die.

That woul dbe my Best Guess with the information that you have supplied.

You can also remove the CPU and ,ake sure that all the pins on the bottom of the CPU and in the M'Board socket are straight if they are not you will not be able to get a replacment unit.

Because of the way it shut off, heat was my first thought as well, but the chip, when I checked it, had a good even smear and didn't seem warmer than usual. Turns out it was the power supply. The only bad thing is I don't know if heat was a factor in the power supply failure. Either way, I'm not running it much until I get an extra 120mm fan to supplement the 80mm it came with.
