Built a new PC but it will not boot to bios, using a ECS K7SOM (mobo) / AMD duron 1100 / 128 meg sdram. When i turn the system on i get a faint whir of the hard-drive, then nothing else (no beep) Keyboard seems like its not there and all i get on the monitor is the orange (standby) light, the floppy is not detected at all, and the light on the CDROM stays on and flashes now and then. All leads are correct (stripe side to pin 1), have played with the jumper settings on both IDE devices and no change, took RAM out and the system beeped, cleared CMOS about 50 times, removed BATT from board tested OK, the only thing i can think of is that the BIOS is not there, which i guess will be a computer shop job, any ideas ?

No Beep: No Power, Loose Card, or Short. remove your devices one by one, and keep trying. remove one ramstick (if possible) and try until you get a beep, then count the beep code. compair it here. http://www.computerhope.com/beep.htm

hello you can allso try removeing every thing out of case and reasemble it on a sheet of card board. and try to boot it if it goes than its shorting to the case. if so make some paper washers for both front and back of mobo to insulate it.

Hello, Try this site for help http://www.computercraft.com/docs/pcdead.html

Yes it maybe a short from the mobo, didnt think of that, there were some fibre washers that came with the board (i never used them) perhaps i should have, but as there seemed to be a washer pressed into the mobo i never bothered with the extra ones...well i know what i'm doing for the weekend :-( well get back to you and let you know the result, thanks... PS...This is the 1st time i have a built a pc from scratch...however i have learned a lot since i started and found some great support / info sites (such as this one).

The beep with no memory tells you that the processor, BIOS, and much of the system board is working. However, you should be getting something on the display. So it sounds like there is a problem with the RAM memory or the display adapter. Can you check the memory in another machine or use a different one? Are you sure its the right type for the system board? If the RAM module is burned out or the wrong type, it will cause the problem you are having. (does it get hot) Try unplugging all disk drives and adapters except the display adapter, display and the keyboard. Then with a know good memory, if nothing apears on the display, then suspect something is wrong with the display adapter. You may have to try another display adapter card, even an old one. The BIOS could be defaulting to the wrong type of display adapter.

There is no "display adapter" with the K7SOM all sound and vga is built into the board (well it better be) :-) the system has not run as yet, so there is no way of telling if it gets hot etc...will try the ram out of "this" pc on the weekend... thanks...
