Upgrading my mobo from Dell Dimension 3000 Intel D865GVHZ (AA C92755-303) to so I can have AGP port [i dont want pci-e].

NEW Intel D865GLC (AA C27500-410) mobo
NEW powersupply Powercooler eXtreme Power Plus 500W
SAME Pentium 4 Hyper-Thread 3.00E GHz (L2 1MB, 800 MHz FSB, sSpec SL7PM)
SAME alternative Pentium 4 2.4GHz (L2 512K, 533 MHz FSB, sSpec SL6EF)
SAME 2 Gig of ram

EVERYTHING works with OLD mobo

will not POST or get into BIOS, just turns on and off in 1 second
black screen
no beeping
front panel lights no blinking only solid green
mobo power LED green at bottom right corner

I tried removing the CMOS battery and switching with old mobo battery already.
no jumper to reset cmos, i tried the bios password jumper.

I tried another CPU P4 2.4GHz sSpec SL6EF which is bios P03 compatible, the earliest bios version so all Intel D865GLC boards regardless of AA number are compatible.

No bloated capacitors.

Does it work with the old power supply? If not, then the motherboard is DOA and you'll need to RMA it.

Remove power cable for CPU supply(4 pin) and restart your Mobo?if it work properly so u have a problem in CPU power supply circuit in Mobo.All power supply using short protect circuit ,it means that when you have a problem in one of output, the power supply go to the off (protect your motherboard for more damage).

Well the manual says "Failure to use an ATX12V power supply, or not connecting the 12 V processor core voltage power supply connector to the desktop board may result in damage to the desktop board and/or power supply. "

Please test your mobo out of case(maybe same short circuit) and check clear password bios jumper position (1-2 is normal) and please reverse polarity of Cmos battery for clear cmos(10sec).

looks like i figured it out myself, i was upgrading a MB D865GVHZ to a D865GLC, the power switch was compatible according to the manuals, they were exact save voltages and such on the pins, but the brown wire i had to cut. it was connecting pin 9 (+5V) and pin 5 (reset). so it was resetting as soon as turned on. did not have to change anything in bios.

ALSO had to use 2 jumpers for front panel audio pin connector, so audio driver did not think headphones were plugged in and not allowing back audio from working. jumper on 5 (right out) and 6 (right channel return), 9 (left out) and 10 (left channel return).
SOLVED.
