Don't ever get frustrated by a Shuttle, ahum, they're marvelous, but just "a little" strange behavior ... they are very sensible to the cell-battery; if the voltage drops below 1 volt... i have been ripping my hair out in the beginning of my Shuttle period... as said they just don't boot... get a multimeter, carefully get the cell battery (ya know, the little round zilver one on the motherboard, check the voltage and replace if V < 2V. If the cell battery has not taken out completely... we always take the cell bat. out to avoid discharging when keeping it in the box for a longer time.
So first check if there is one in at all...
!!! whatever you do inside your baby, get yourself grounded !!! a static voltage can destroy the little bagger...
--- Then you should check the jumper of bios reset. Could be it is in position "I" this should be changed to cover the "0", its very clearly described in the manual you can download @ <a href> http://us.shuttle.com/barebone/Models/SG41J1_PLUS.html
download the manual and try to read it careful where the bios is described.
in 2nd stage it could be the memory, which is not inserted correctly, meaning not seated well. ( no offense, but it happened to me too... ;-)
Shuttles are different to handle...
- Also check, what speed the DDR stiks are... and also, if they are supported by the board.
- Check if you per error got some ECC mem stiks, they would not run. I remember going through such a case too...
as said, check if the compatibily book says if the mem-sticks you own are compatible.
- Then check if some wire is loose from the mobo to the disc, DVD evtl.
-- Check the wires from the front contacts to the mobo... maybe loose contact...
--- Last i would set the BIOS reset jumper to empty BIOS position , leave it there for approx a minute or 10... and if that does not help, check if maybe a addon VGA card inside is not well seated. or some other addoncard.
and lastly there can be some problems in the hdd itself, cables to discs, short-circuit on the underside of mobo or at the outerlast the thingy is broken and yore doomed to try to get your bucks back...
Hope i could be of any help mon ami
If not, just come back and write what happened, all volks here are glad to help,
