780i stopped working

post #1 of 8
Thread Starter 
Well guys this was running 100% for the past three years. I just got a new hd, win7 and 570 card for my rig. Took the old parts out put the new once in moved some wires around and started it. a red led light came on, on the board and the led on the board did not go through the codes it just said ff. it always say that put it scans through all of them when she starts up. and no video out put with the new card or the old one. So I took everything off and started from there. I took the board off the case floor and put a foam pad under it. the red led right light came on and I moved the video card around and it turned on and it was fine. I took the foam pad off and it did not work. I thought a had a ground problem but that was not the case. I put in a friends back up motherboard temp. in and it worked fine. the only thing I can think of is I flexed the board when i put the video in or I hit something on the board that I did not see. Dose that sound like the case and is it dead guys? and if so whats a 100% match I can buy to get. a different brand is fine. its a dd2 memery too.

thanks

FF is the 'boot' POST code, so if you're seeing that, then the problem isn't the board. Have you checked that all the mobo power cables are correct and that there aren't any extra standoffs behind the mobo that would be shorting it? Could also be a dead HDD? Give us some more info if you can and we'll be able to help more...

Is the board beeping or screeching when you power it up? That could indicate a poorly seated/shorting graphics card or other expansion card.

Edit: Have you tried resetting the CMOS?

ok

Yes we unpluged everyting the power feeds and basic just to see if it would turn on.

ow sorry yes when the red led lights it beeps too. My thought at first was when we pulled the lines out of the back becasue we need more room for the hd lines I thought maybe we cut the line. So thats why we disconnected everything. kept just one memery stick in no hd, cd or anything and it still had the problem moved the card to both slots and still nothing. thats why we put my friends board in to see and it worked fine. granted its basic gigabyte board.

Have you tried resetting the CMOS?

Have you tried a different GPU or that GPU in a different board?

Reset the CMOS twice just to see.

Yes my 8800gtx then new 570 and he had an old ati all did not work in both slots and had the same problems.

That was are thought at first was to try another power supple but we did not have a extra one to use. but if its working with his board I would think its fine. I have been running it now for the last three hours and its fine with his motherboard.

we did not try that on the board but he did have a back up old daul core we put in his borad and then my cpu and they both wrok on his board. did not try his cpu on my board because it was 2 at night and both of are gf where pissed.

I have been looking for that past two hours and I cant find a good board that matches the power of my motherboard. its looking like i7 is coming. not that i want to spend $700 on a new cpu, mb and memery.

Unless you're trying to go tri-sli the 780i isn't necessary, you can still find them kicking around FS threads here though. I can't believe the board is dead though if you're getting it to turn on and light up and screech at you...
