Upgrading my motherboard from Dell Dimension 3000 Intel D865GVHZ (AA C92755-303) to Intel D865GLC (AA C27500-410) so I can have AGP port [i DON'T want pci-e].
SAME Pentium 4 Hyper-Thread 3.00E GHz (L2 1MB, 800 MHz FSB, sSpec SL7PM), SAME 2 Gig of ram. NEW powersupply Powercooler eXtreme Power Plus 500W works fine with old motherboard, i dont think thats the problem. BUT on NEW motherboard will not even POST, just turns on and off in 1 second black screen. The front panel lights don't blink except solid green on power indicator. I can see a green light stays on at the bottom right of the motherboard, indicating its getting power maybe? I think maybe the CPU is not being recognized as BIOS is not up to date (P13 or greater). But there is not way for me to check the BIOS version.
I tried removing the CMOS battery and switching with old motherboard already too.
