I had problem with a sv266a new build, just had mobo, ram, cpu heatsink fan, agp, pwr switch and speaker connected (with mobo in box)
I decided it might be shorting as I hadnt used insulators, took case out put it on mobo cardboard box and it worked, but only for the first time and not again?
any ideas?
also where exactly do you put insulators
many thanks for any help

Hello
If your board is an ATX board you put the spaces at the holes on the board, there are six holes on small ATX and nine holes on medium to big ATX boards, there are silver circles with holes in, on most boxes they have either a screw hole so you can put a hexagon spacer there, or they are square clips, that slot onto the box, and then tou screw the board to the clip, this type of configuration is beter it dose not transfer the noise across to the case.
If the board as touched the case then it may be damaged, but i would try it outside the case just to make sure it is not working, did you also try to reset the bios chip, it may be some setting in there that is causing your system to hang, like if you tried to overclock it, then this may cause the system to hang and not load. Please note when reseting the bios chip do not have any power to the board this may damage the supply to the bios chip.
Regards
Andrew

thanks for that, i've got the hexagon spacers, so is the order: case, hexagon spacer, mobo, cardboard circle, then screw? (is the insulator the hexagon spacer or the cardboard circle?)
maybe I have damaged the mobo when it has touched the case, but nowt happened between the only time it got to the stage where it says XP1800 (on this page it said checksum error?), and then the next attempt when it didn't work, maybe an intermittent fault has developed?
There are only two jumpers, bios reset and 100/133, both are set correct, so maybe it is a mobo fault, but that seems strange for the reason above?
Thanks
Dave

when i put my mobo in i didnt use any spacers or anything. i was told the mobo needs those contact points with the case as a ground.
my mobo works fine though
