hello, im new to this forum and i dont know where else i can ask for help regarding old pc parts. i recently bought a new cpu for this motherboard (pentium d 915) to replace the older Pentium 4 506. i installed the new cpu and tried booting it up with the latest bios (int this case ver F4) even though the new cpu is listed in the cpu support list of the motherboard on gigabyte's website, the pc didnt turn on, so i put the older cpu in to atleast be able to use the computer and planned to return the new cpu but unfortunately even with the old cpu installed the computer now doesnt boot at all, the secondary system fan spins and the psu fans spin but the cpu fan doesnt spin and nothing is displayed on screen either, initially i thought the motherboard was dead so as a last ditch attempt i took out the cmos battery of the motherboard to see if it was a bios settings problem, my custom bios settings make it so the computer doesnt turn on immediately and only turns on after the power button is pushed and the default settings have it so it turns on iimmediately after receiving power. after i removed the cmos battery, the secondary fans started spinning along with the psu fans so i guess the motherboard isnt dead and during all of this both the old and new cpus get hot (ive touched) along with the chipset so what the hells the problem here why cant it post???

Welcome to the forum, @vanakkam .
To begin with, I’d suggest getting a POST diagnostics card, like this one:
It can tell you where the board is getting stuck in the boot process. Also, take a close look at the CPU socket to make sure that there are no damaged pins.

i think one like this would be sufficient (https://www.amazon.in/XIKKART-4-Digit-Motherboard-Diagnostic-Testing/dp/B0C96KTPQ7?) just ordered one, ill keep u updated on what happens

This is one of those weird transition boards from 478 to 775. The 865GV chipset was really a socket 478 chipset that was jimmy rigged to work with LGA775 processors. It was primarily designed for Celeron and Pentium 4 chips. Board vendors used voodoo and black magic to get some Pentium D and cut down Core 2 parts working on them, but it never worked well. This was a low budget board when new and had the typical corner cutting in designing it.
I would recommend checking the LGA socket for bent pins, and the pads on the CPU for damage. It's also entirely possible you had a bad Pentium D, or a sSpec of it that doesn't work with the board. Weird budget boards like this were often sensitive to individual core revisions of the processor, which can be the difference between working and not.
