Whole bunch of issues (DFI LP DK-790FXB-M3H5)

post #1 of 4
Thread Starter 
First off, sorry if this is in the wrong subforum.

I built my sig rig about two years ago, and every now and then when I open it up, close it, and then try to boot it it won't even POST. What's odd is that fiddling with the CMOS reset/discharging the board in some random order will fix it, and then it will work with zero issues for an indefinite amount of time. Well, I finally upgraded from two 1gb HD4870s to two 2gb HD6950s. It worked with no problems for about 4 days, then windows decided to start BSODing on boot (which I was able to fix), and then on Saturday it decided to not POST again.

Of course, the LED codes I'm getting aren't even in the manual and DFI quit making LanParty boards last year.

Sometimes it will go -8 (???)->C1 (memory issues, so says the manual)->02 (????) and just sit there.
Other times it will go right to C1 and sit there. Very rarely it will actually post but then says something about not being able to apply a CPU overclock (which I've never set up in the first place), so I skip past it but then my OS drive isn't the primary boot drive so I have to restart to go into the BIOS and fix it. Problem is, when I try to reboot it to go to the BIOS it just starts doing the same crap over and over again until it posts again.

New RAM, new motherboard, or is it fixable?

If there's a problem with the motherboard, you probably can't fix it. If you've got an alternate set of RAM, I'd put that in there instead of your current to see if it's a memory problem.

Swung by a friend's place who let me borrow a 4gb stick of good DDR3 1600, popped it in, and it's still not posting.

welp, time to go motherboard shopping I guess. thanks for the input.

EDIT: Fixed it, turns out I'm an idiot. What I thought was a button to clear the CMOS was actually a reset button. I found the jumper to clear the CMOS and the whole thing boots up with no problems.

Next time I'll read the manual first.

Sorry for the double post but now I'm getting CF at boot out of nowhere, no switching of RAM will fix it. I don't get it, it was booting and running fine last night but now it's giving me more problems. The manual says updating the bios may fix it, but 1) I can't even get the machine to POST, let alone get into the BIOS and 2) The last time I tried updating the BIOS from a USB stick it just... wouldn't do it. I put USB-everything into the boot sequence and it just flew right past all of them and to my hard drive. Starting to hope that DFI goes completely under.

Should have just bought an ASUS board in the first place and been done with it, this is getting ridiculous.
