System dead? Your opinion please!
I built a Shuttle KPC K45 last fall for my office at the church and it has been fine until I decided to swap the a430 1.8 Celeron for an new one... e5200. The machine worked great when I shut it down but will not restart.
I have taken the following steps to try to isolate the problems...
1. Disconnected the HD
2. Removed memory
3. Put the Celeron 430 back in.
4. Reset bios
5. Removed bios battery and reinstalled it
6. Tried PCI video card on DVI and VGA output
All of these yielded the same result: The power comes on, HD and fans spin up as expected but the display will not come on (both onboard and additional video card)
Thanks in advance for your help!

You've done most of what you can I think. A couple pieces of advice:
Keep the system minimalist until you get a POST screen. This means, no HDDs connected, only one stick of RAM, no PCI/AGP/PCIe cards installed. Run just off the on-board video.
Reset the BIOS. Try booting up.
Next, the only thing you can do is swap out parts. Try different RAM sticks if you have compatible RAM. Try the different processors (make sure they're installed correctly!). Get a PSU from a working computer and hook it up.
The only reasons I can think of for this kind of failure is a bad CPU (incorrect installation or failed part), really bad RAM that the system doesn't recognize or shorts out, bad PSU, and bad motherboard. You can't fix or replace the motherboard (I think) so that's a worse case scenario, and its hard to diagnose, so you just have to eliminate the other possibilities (CPU, RAM, PSU).
I had a similar issue before with a full-tower desktop/server system. It turned out that the Enermax PSU wasn't delivering stable power.

In my experience bad boards and bad cpus will boot (start the psu, fans run, but no display) but will not shut down from the power on button and have to be stopped by the switch on the psu.
I've read that when trying to guess whether it's the cpu or motherboard, look at the leds on the keyboard. If they flash once during the boot, the board is probably okay.
I test new or used boards and cpus by booting with the minimum parts connected: board loose on a nonconductive surface (folded newspaper) with cpu, hsf, ram, video card (if no onboard) and monitor, and a keyboard (PS/2 if possible). To start you can use a switch on the pins or a momentary touch with a jumper. Be careful of shorting on other pins if you resort to starting with a screwdriver or other metal object.
It saves time if a new board has problems, and a dead board will be removed before tossing anyway. And if a screw has rolled under the board or there's a misplaced standoff, booting loose will negate those problems.
Since parts can easily be jostled while changing the cpu and hsf, you have removed and reinserted the ram and any cards and power connectors, of course.

But... but...but...
According to Shuttle... the e5200 does work and I have read of others using them in the little cube.

I couldn't find any specific info on the 945GC, but after a couple google searches, I came across the list I posted. I'm not saying it won't work, stop trying.Trav1s wrote:But... but...but...

That's weird how Intel and Shuttle say two different things... sort of.
I'd give shuttle a call.
Do you have the latest bios? Is it possible a new bios is needed to support that CPU?

* I know that this sounds silly, but have you tried another monitor?
* Does your motherboard have speaker connected? If yes, does it emit any beeps while booting?
* You said HDD spins up. Does it start seeking (like while normal startup)?
* I hope I did understand correctly - yuo have tried booting up without any RAM on borad. If not, then try - I've cured one motherbord this way.

Yeah. I've fixed one computer that wouldn't post because of this. It might seem like a PSU failure wouldn't allow the fans or hard disk to spin up, but if the voltages/signals to the CPU are off, this will happen. I had only tried swapping the PSU as a last ditch effort (because I couldn't think of how a PSU failure would stop the mobo and not the HDD and fans) and it worked.Arvo wrote:* Have you tried another PSU?
Ok... here are all the steps I have taken to isolate the problem.
1. Makes no sound during power on. The K45 does NOT have an external speaker and the external speakers produce sound.
2. I have powered up the machine with processor(old and new)/memory, with processor/no memory, with memory only. Still the same behavior... No video display.
3. I have tried two different monitors with various combos mentioned above.
4. Swapped power supplies without success
5. HD spins up but does not seek like it did before.
6. Reset bios by jumpers and also tired removing the battery.
Not sure on the bios, can't get the machine up to check version.
I will give them a call and see what I need to do to get a replacement board as it is covered by a 1 yr warranty.
Other than this, I have been quite happy with these little boxes. The other k45 (using right now) is a sweet little hackintosh
