computer with booting problems

[scottatwittenberg]

biostar 6100-m7 motherboard
1 gb corsair vs
s64 2800+
antec smart power 500w
wd 80gb 8mb cache ide

so everything was working fine... then i went a changed the fsb from 200 to 210.. after that, the computer didn't boot.. so i put the fsb back too 200.. it still wouldn't boot.. it would get to the "veryfying dma data..." then it would show boot from cd-rom drive things.. i then discovered that i could get it to boot if i hit tab to show the normal post screen instead of the fucking biostar splash screen, then from there click F9 and choose the hard drive and it would boot..

this was last night using a 350 watt codegen psu.. today we got the sp 500w hooked it up.,. and the thing booted all the way into windows without any problems.. this was on a 60gb 2mb cache maxtor though.. we dropped in the wd 8mb 80gb drive.. installed windows.. and all was fine.. but now it won't boot at all.. it goes through the post screens but just blanks out after the verifying dma data.. thing...

so.. i have a feeling that the ide channels crapped out..

i have reset the bios with the jumper 5 times or so..
i have tried the hard drive on both ide channels..
it has done this with 2 different hard drives
it has done this with 2 different psus
it has done this with only 1 stick of memory.. and i tried both individually

what should we do next? update the bios?

when it does boot into windows it runs fine..

i am thinking that we might have to just rma the board.. i wish we had an sata drive to try on it..

also.. the voltages are all low.. even with the new psu, which has dual 12v rails...

thanks

ok.. i figured out one problem..

i disconnected the dvd drive and then tried again and it fired right up.. so i thought maybe it was a problem with both opticals being master, or one of them shorting out.. so it was running for a good hour..

i restarted it though to see if it would still work.. and it wouldn't start...

so then i was thinking.. ok.. something is overheating.. it will cold boot fine.. but it won't boot after being run.. so i start feeling around and the southbridge was hot...

i was touching the actual southbridge.. they forgot to put a heatsink on it.. and the HS on the NB is too small... so yeah.. i am getting on the phone with newegg tomorrow to try to figure out that one..

how could they ship a board with no southbridge heatsink? and get the one on the NB wrong? this board is supposed to be new.. it came with everything that it was supposed to come with.. but i did get a refurb shuttle once from NE after ordering a new one...

anyone know what specifically is controlled by the SB on that board?


also.. this is unrelated, but the voltages are all showing up as being real low.. replacing the codegen with an antec smart power with dual 12v didn't make a difference.. i am just assuming that the sensor is off since i have run the computer with just the 24pin connector, that 4 pin on the mobo and 1 molex going to the hard drive...

I have had a couple of Biostar motherboard in the past and will not touch them again. I had too many **Wierd** problems with them. The southbridge depending on the chipset usually contrains the Drive controllers, Sound Card, USB, Firewire etc, if I remember correctly.
