Thats the back of the mobo.. where the thermal heat pad goes. Its my understanding that it just gets to 5c, so it shouldnt do such a thing?

It wasnt overclocked at the time, just put in a new video card, and sound card (9800XT and Audigy 2 ZS :) ) and was just browsing the web, when all the sudden my PC shut off.

Tried to restart it, I couldnt get a display on the monitor. The fans spin up, mobo led's come on, but no display. Tried a my old 9800 Pro since I just installed the 9800XT just before it happened, nothing. Tried a old GF2 MX to make sure, nothing. Tried some different ram.. nothing.

Took my CPU out and put in a 2.4c I got, nothing. Took my 3.0c and put it in my other PC with a Asus P4C800 Deluxe, and it worked fine. So after trying all sorts of different hardware, I was thinking it was my mobo. After taking it out, and looking it over, I saw the problem. So now I have another one ordered...

Only two things I think it could be. The thermal pad somehow got too hot, or not good enough contact between the microfreezer and my CPU, see thread here (http://www.ocforums.com/showthread.php?s=&threadid=251834) There is some contact, but not much at all. Could condensation be the problem? I STILL havent gotten my new clip they said they sent out two weeks ago last Wednesday.. I think they should have at least made sure it was here in 2-3 days, as it was their error. I emailed and asked if it was in fact sent out, someone said yes, and if it wasnt there by Jan. 5th to get back to them. They are all off until then :rolleyes:

Those two contacts are directly under the CPU, so not sure how condensation could even get under there. It also was sealed very well, and has been running for about 2 weeks with no probs. Just my CPU temp was only about -10c, not -50c where it should have been. So it would seem kind of odd that it just happens. Perhaps when I shut down my PC for 10-15 mins putting in new stuff, it got warm, condensated, and when I started it back up, zap?! It happened about 1 hour after I restarted it, so that is even unlikely. Or perhaps, just got a bad mobo, and nothing I could do about it.

Corrosion is caused by water. Was it insulated properly?

that mother board hase alot of holes did you put dilelect grease on it to seal all the holes off

No, no grease at all. The instuctions didnt say anything about it.. The holes shouldnt matter I wouldnt think if the seal string was installed properly, which I believe it was.

Yes it was insulated just like they showed. Redid it a few times just to make sure.

Have you tried cleaning off that corrosion with some alchohol? It could be causing something to short out, maybe? How long have you been running your board with your Mach II?

No I didnt try to clean it. I just ordered another one. Ill probably just keep this one in my pile of old parts. I may try to clean it up, I didnt know you could do that. Right now I am on my P4C800 Deluxe, with just a heatsink/fan combo.

Ironic as it is, after 16 days my correct CPU clip finally showed up. If that was the cause of it, its ironic that it showed up the day after it happened. :eek:

5°c? Are you sure? I plugged mine in and after about twenty minutes, it was too hot to touch! After running my Prometeia setup for about a week, I took my whole system apart and when I removed the heating pad/plate/thing, it appeared that it had slightly melted!

I now have the thing undervolted to 7V and it doesn't get so obscenely hot.

Apart from that though, I did notice what appeared to be a little corrosion on the back of my board (where the heater was), although it was nowheres near as severe as what is shown in your pictures. I just used some 99% Isopropyl alchohal and a paper towel to remove it.

I don't think anyone said it above, but that's from not sealing your chamber properly in the back. If it's any sort of a good seal with that heating pad you shouldn't have condensation, so be liberal with the seal string. :)

Oh - to add, just use some alcohol and scrub that stuff off - it may be good as new.

Hmm, Ill try that soon. Thanks for the heads up.

the heater element i measured goes to 70-90C and is hot and nVentiv say that's normal... i guess you didn't put enough seal string to spacer the back plate from the board... or it could be condensation causing it

that looks like condensation from the pic, sorry for your misfortune:(
