Shuttle X PC - HD + Power LEDs briefly illuminate, no boot.
Last night I shut down the machine as usual. Went to start it again via the power button on the front today. All that happens is the Power (blue) and HD Activity (amber) LEDs illuminate briefly (about .25 sec). Nothing else happens at all -- no fan, no HD spinup - it's completely 'dead' apart from those LEDs blinking on once.
I've done the usual: re-seated the AGP card and RAM, removed and reinserted the CMOS battery, attempted power-on without any external or internal (non-vital) peripherals connected. Still no luck.
Any ideas what to try next?

Re: Shuttle X PC - HD + Power LEDs briefly illuminate, no...
It sounds like you have a bad power supply. It will store up a very small amount of energy (enough to run some LED lights) but not enough to power up the system. That's where I would look. If that is not the problem, then I would look to the capacitors on your motherboard. Good Luck!

When you say you tried the HD in another machine did it boot? Generally when you slave one drive onto another it's the other or the one inherent to that PC which does the booting and then you'll be able to see the drive you just connected. If this is the case copy all the data off that hard drive that you need to keep. Now put the drive back into your shuttle and run a Windows repair to restore the master boot record. Good Luck
Power supply is easier to troubleshoot my local pc shop has used ones for $5 or if you have one laying around make sure you have one with the proper mobo connector 24pin will sometimes fit 20 pin as long as there are no transistors to close to plug just turn pc off unplug all drives and mobo plug in good supply and turn on if it works thats the problem if not probably mobo
Update from my immediate post today: I've looked at other post that is suggesting memory or battery problem. To my surprise, after removing one memory from bank2 of DIMM, the PC came back to life! Whenever the second bank has either memory stick in it, it will stuck. So I ends up with half the memory, but get my system back. Not sure how long this will last though.
I Had similar history as the initial post: runs OK, and started random shut down 2 days before final stall. I am putting back my HDD and system, should be working, for now at least.
The "No Signal" display is an indication that there is no video output from your PC going towards the monitor. Cycling the power on/off a few times before the unit will start indicates there is a problem with the PC basic configuration. This may include: 1. Defective, dirty, loose memory sticks - clean or replace; 2. Defective, dirty, loose video card - clean or replace; 3. BIOS/CMOS settings too aggressive or not stable - set to default;
You can also try resetting the CMOS/BIOS to default settings by moving the reset jumper from its original position to the opposite end (1-2, then make it 2-3) temporarily. The reset jumper is normally very near the Lithium back-up battery. Alternately, removing the battery for an hour would also do the same, reset.
In some instances, it is the CPU fan blower that does not startup causing the system to halt. If so, it needs to be removed, cleaned, lubricated and re-installed.
At other times it can be cause by devices nearing end of its life. These may include the HD and the CD.
Still, this could also be caused by external devices which cannot be accessed/read at the startup such as a flashdrive.
Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.
