View Full Version : Trip + Burning smell (long post)

07-10-05, 07:36 PM
I have an MSI Platinum SLI mobo, the one that has the stupid flimsy SLI-selection mechanism (anyone else with this board will know what I'm talking about). Anyway, so one fine day, the inevitable happened: the little plasticky thing that held the selector board in place popped off, and the selector card came loose (it was still slotted -- somewhat).

Coincidentally, my 6600GT fried near about the same time http://www.nvnews.net/vbulletin/showthread.php?t=53044. Actually, the only reason why I noticed the loose SLI selector was because the GT fried and I was looking inside my case for abnormalities, and the selector may have popped off quite a while back (as I mentioned, it hadn't *completely* come loose, it could still have been functioning). I figured the reason why my card was behaving weird could have been the loose selector. I managed to place the stupid plastic thing back in place and the SLI selector was firmly secured once again.

That's when the fun started.

I restarted my system, and... poof! The PSU tripped after switching on for a fraction of a second (I have a 535W $110 Enermax). To my horror, I could smell the familiar burning odor of a short-circuit :eek:. I tried hard, but could not isolate where the smell was coming from. Within a few minutes, the smell vanished. For almost an hour, I tried to look for signs of something burnt in my system, but couldn't. I almost took the whole thing apart in an attempt to look at each component closely and re-assembled it. But no, no sign of anything wrong at all.

I dared to do the unthinkable. I reset my PSU, plugged it back in, and moved myself as far away from my system as possible. Stretching out my trembling hand, I managed to locate the Power on button. I looked away, took a deep breath, and applied pressure on the button...

... the sound of 7 fans revving up filled my ears. After a few seconds, I heard the beautiful, familiar, BIOS <beeeep>. I went back to my machine and switched on my monitor. Everything was okay! Windows came up, and I started Guild Wars. The system froze, but I was kind of used to that by now. My graphics card was truly gone.

So, there it is. I ended up exactly where I started -- a fried 6600GT. My system's in the exact semi-operational state that I started out with (please see my other thread if you're interested in the details). What I'm confused about is what in heavens name all the other intermittent stuff was about -- the loose SLI card (that may or may not have had anything to do with anything), the tripped PSU, and the short-lived but distinct burning smell :confused:.

I'm going RMA on my 6600GT, but I'm not sure if there's anything wrong with the rest of my system, specifically the PSU. It seems to work perfectly, I tried out another graphics card (one that draws far less power than the 6600GT, though) and everything seems *perfect*. Any clues? Is my system safe?

You better RMA the motherboard, also....sounds like it might be the "root" problem, you might end up killing the replacement 6600GT, too :(

Hmm... is it really possible for a motherboard to blow up a graphics card?

Guess you checked the contacts on the card for any signs of arcing? If there is any discoloration on the gold contacts of the card that is a pretty good sign that the agp slot was the source of the burnt smell.

You mean PCIe slot? ;)

Just checked... PCIe contacts are sparkling clean... as are the contacts on the *STUPID* SLI selector card. I pulled out the damn thing one more time to check... and in doing so I'm sure I reduced its MTTF by several years.

By the way, is it okay -- contractually (through warranty) and ethically -- to RMA a product that you *suspect* is damaged? For instance, I am sure my video card is trashed, but I'm not quite sure if my motherboard is. Or is that exactly what RMA means: "I feel something's wrong, could you guys please check it out?"

Just say "it's giving me trouble" which is true.

6600 GT's are well known for their elite ways of amazing overheating and frying...
:D thats why i got a 6600, not the GT, becuz all i hear abotu the GT's is that they overheat

And I learned the hard way.

Wish I could get a 6800 vanilla in exchange. The PCIe version does not have hidden secrets, but it seems it is very overclockable, prices are down to the 180's, and it comes with a 256-bit bus :luv:

what do you mean you should be able to unlock the 6th vp though your still stuck with 12 pipelines. I'm happy with my 7800GTX.
