Hi All,

I'm putting together a new system. The motherboard is a p4p800 Asus
mobo. The cpu is a p4 2.8 c, pc2100 ddr. When I put everything
together, the mobo does not post. The cd rom drives light up, blink
and then go dark. The green light is on, indicating that it is
receiving power, as is the cpu fan. I've checked the power to the
mobo with the 14 pin and the 4 pin connectors. Can someone help me
troubleshoot this problem?

Thanks,

Joel
 
If you have more than one memory stick remove all except the one in slot
1 and try to boot. If it works you have a bad memory stick. If it fails
and you have a second stick swap to see if the first is bad. Also I
recently had a problem during upgrade wher dealer gave me one stick with
chips on one side and a second with chips on both sides, both 256M DDR
3200. Machine already had 2-256M chips in slots
1 & 3 (ASUS p4p800). Machine would not post or boot with the double
sided stick installed.

Good Luck, John
 
I should've mentioned this in my opening post, but I'm putting this
thing together with no memory in, no hard drives attached. I've even
removed the CDROM. This should remove problems arising from hardware
conflicts (eg. bad memory, bad drives, etc.).

LOL.

The system must have memory installed to POST.

The absolute minimum required for any system to post is CPU & Memory.
"Almost" all boards also require a video card, which is pretty helpful
regardless if you'd like to see what's going on. A few boards also
require an RPM signal from a CPU heatsink fan, but "usually" they'll post
anyway, just giving a warning about it.

The drive(s), keyboard/mouse, sound, other cards aren't needed to POST.

If the system still won't POST you might try clearing the CMOS and
checking the onboard jumpers, if there are any.
