No, but if it happened, I'm willing to bet it's an issue with your PSU.

What are the symptoms?
could be because your temps and high OC.

Sure. If the GFX card is overvolted by the mobo via the PCIE slot. This could be due to bad vregs or something like that. I would also look at the PCU. Why do you think it is the mobo? (575W with no name??)

Well the symptoms started out not posting right. would hang on post sometimes. woldnt save any changes in the bios. and then it just quit. I got lights and fans but nothing else. no beeps or nothing. I started pulling it appart and notice a small chip on my gpu had blown? And my psu is a cheap logisis 575w make (junk)

Then yeah, replace that PSU ASAP.

You better hope and pray that it didn't take anything else with it when it died too.

I have another thread that we have been disscusing if it was my mobo or cpu that had fried and after doing all of the elimination processes I about decided it had to be a bad mobo or corrupt. Then I pulled the gpu and noticed a blown chip. But the mother board still does not post or beep for an accepted post so I figured it was bad to start with. My leds sey FF on the board when u turn it on.

Got a corsair 750w on the way. I hope it did'nt take the cpu to.(probably did) Seems to have got everything else.
YES I have. The voltage controller on my first 790i was messed up, and it fried both of my 9800GTX's at the same time. I had to RMA them all at once.... man I was ticked off.
Yea really sucks.. Glad I did'nt have the other one in yet. Whats the cost on having one rma'ed?

what do you mean? RMA'ing is generally free, except for shipping. You generally do have to pay shipping both ways... so it does get rather expensive, especially when sending in 3 items at the same time.

EDIT
you have to pay for shipping there, not back. Still sucks

I'm pretty sure I had to pay for shipping back... I know I had to pay for shipping there.

OK I just checked: you do pay shipping there and not back. Still I think I had like 30 dollars in shipping charges when I RMA'd all that hardware.

If you handle it right, you may be able to get shipping paid both ways. RMA is more of a PITA just for having to go without for a month or two. (well, depending on the company) I am awaiting a DFI RMA at the moment.

so when you turn the pc on it goes until FF on the mobo that usually means fully functional

and does it usually beep after booting

and if you complain a lot they will usually pay shipping both ways

oh and xfx has a the fastest turn around i have seen so your gfx rma should be quick

oh and about the original question yes i have the DFI DK P35-T2RS now and it has something to do with either the pci/pci-e bus voltage or frequency or maybe both as it has killed 2 sound cards 1 modem 1 pci wireless card and going on 3 video cards (8400gs, 4830, x800) and anything connected via pci on the board is either broken (ide controller) or acts funny but its not the dfi's fault we were trying to kill my friends old 7800gtx and we just couldnt we ran it without the fan pulled the heatsink off in a video game took off the memory sinks and vrm sinks and ran it oc'd like that for almost a week he came over one day while i was at work and i told him to try and kill it as i couldnt seem to so he drug aluminum foil across the back till a vrm popped and when we put a new card in my board we found that all the pci cards in it at the time of the vrm failure were dead along with the ide controller and it has gotten worse since then

Ouch....

PCI-E Freq kills cards... Its a known fact... My 8800GT at PCI-E freq of 120 was stable for over a month. one day i started getting instability so i clocked everything but pci-e down to stock, ran fur mark, after about 10min i came in to a burnt card, you could smell it...

thought maybe PSU, but after setting pci-e back to 100 and running this psu for another year now with 2 8800;s and now a 285, I have to be convinced it was that pci-e freq that did it.

Yes it can...My old MSI Eclipse burnt itself and my 3870x2
Appreciate the help guys. That seems to be what has happened to my board. And it took alot of casulties w/it. guess I'll get the Rma process started. Do a little complaining and see what I can get on shipping. Again thanks and reps added.
