sweet, new mobo (biostar amd board) now computer won't post

i just purchased a BIOSTAR GEFORCE 6100-M9 motherboard, and like always when i get new parts and try to start from scratch, i'm having issues.

other computer parts involved:

AMD Athlon 64 3200+ Venice
A-DATA 2GB (2 x 1GB) DDR 400
onboard video, audio, lan
liteon dvd drive
2x seagate hdds

after assembling everything, the power light comes on, fans spin, hdd spins, and the computer doesn't post. the manual is awful and has a troubleshooting table that is only half a page long, so it isn't much help. it only says that if lights come on and things spin then push down on the ram to make sure they are in securely.

i've moved the ram around to all the different spots & tried ram from another pc so i don't think that is the problem. i've tried booting without any optical drives connected and i get the same result.

the one possibility is the power supply. the board has a 24 pin connector, but my supply is only 20 pin. research has told me that it should still work as long as it's plugged into the 20 right pins (and it only fits a certain way so i assume it is), but maybe it's the issue.

could the problem be as simple as needing a new psu with a 24 pin connector? i hate my luck🙁
 
You can always try a 20->24 pin adapter, but I doubt that's being an issue. Try taking out any peripheral cards/devices that you may have plugged in... get it to the bare minimum. Heck, you can even remove your memory and see if you get some POST codes from it.
 
i don't have any pci cards plugged. it's all onboard other than the optical drives. i will try to see if anything happens w/o anything in other than the cpu

that could be it and most likely it is. looks like there isnt enough power going to the system without those extra 4 pins.
i would try an updated PSU with those pins, i bet it'll fix your problem🙂
 
no post codes or anything. psu fan spins, cpu fan spins, and nothing happens. i couldn't have a bad cpu could i? the cpu has worked perfectly fine through all the other problems as far as i know (no oc'ing either).

could it be that the psu is in the process of dying or something? i'm running out of ideas.
 
according to the manual, the 4 pins that aren't in use are a +12V, +3.3V, +5V, & Ground. would that be enough to make things light up/spin but not boot?

I doubt it. People've run more powerful systems than that without the extra 4 pins. Do you have a 24-pin PSU lying around (maybe in the PC that you're on) that you could try? If you have a hobbyist store near you, try to find a 20->24 pin converter to see if that'll make a difference. I doubt it will, but the small price for testing is worth a try.
 
no store close by for that adapter, thinking of just going to best buy and getting a psu w/ 24 pins to see if it works. if not i'll just return it.

if that's not it, i suppose it's either a bad mobo or cpu?

not dying, LACKING PINS/POWER to the mobo
 
got a psu from best buy with 24 pins, still nothing.

i guess i will be rma'ing this mobo back to newegg.
 
on a side note, it's super annoying that i paid overnight shipping to get this so i would have my computer working in a day, and now i get to wait an additional week plus unless i want to pay for more fast shipping to get it to them.
 
!)Try clearing the CMOS first.

2) Motherboard *could* be grounding out on a mounting stud...remove the mobo and put it on a nonconductive surface and try firing it up again.

My system is quite similar to his, except I also have a discrete GPU (7800GS) and I've used a 20 pin plug on a 24 pin mobo for almost 2.5 years now. I doubt that's the problem.

clearing CMOS was one of the 1st things i tried, but thanks for the suggestion. i'll try your 2nd suggestion.
