Anyone else get a strong offgassing smell lasting over a week when using
anything close to the following combination:
P4C800 Deluxe,Antec Sonata,Matrox G550, Mushkin Level II 3500 256mb, P4
2.4C stock, bios 1014, XP(runs fine).

Smell is more of strong offgassing as opposed to burning - not strong
enough to drive you from the room but you really don't wan't to be in
there - after a week normal running, a fair few sandra burnins and just
plain idling.

MB temps 24-30, CPU 30-36, HD 31-46 all during sandra burnins.

No front panel cables are connected to the system board.
Smell persists with or without front case light connected.
Smell persists with or without using Antec 380s fan only connectors to
fans, with or without case rear 120 fan or extra vantec stealth 120 for
cooling HD. Have untied all PSU cables. No visible hot spot on board.

The G550 is warm to touch but no different than running in the other
system. Looked for unused system board mounting stud but no such luck.

I have swapped in a PS from another working system with no improvement.
Swapped out CPU, HS and fan, G550 into another system with no smell.

Rma'd board after a week and new board has same smell (although only
after 1 day).

Any ideas?

I have the same mobo and cabinet and all cables from frontpanel is wired.
No problems here at all from the beginning.
Any ideas?

Tried to unplug hardrives, cd-drives and gfxcard and put your nose close
close to them after a few hours of power-on?

But depending how new your mobo is it can have such a smell for 2-3 weeks
because it needs to "burn off" - if you understand. I tried that with my
old asus k7v mobo when I bought it. And actually any new electronic smells
now and then, no matter what it is (new radio, telly, comp etc).
 
I built a very similar system (see pasted detail below) this weekend, but
none of the strange symptoms you are describing are duplicated.

A complete burn-in has been done, and all front panel connectors are
connected to the proper spot on the motherboard.

With your replaced motherboard repeating your symptoms, I'd suggest you look
into the case PSU. Maybe a ton of cat hair got sucked in there? Or maybe
just a funky smelling PSU?

Don't you hate that smell ? I thought it was just me, as many people
claim they cannot smell it after a week or more. I seem to be able to
detect the smell really well, as even if the computer is turned off
and unplugged, I can smell it sometimes if I walk within a couple of
feet of the computer.

My theory is the chemical is a flame retardant applied to either the
Antec PS or to the whole of the inside of the case. I tried cleaning all
the metal on the inside of the Antec case with rubbing alcohol (propanol),
but that made no difference.

I cannot say that I enjoy living with this stink, as it tends to fill
the room while the computer is running. Some day, when I can afford it,
I'll get another case and a separate power supply from some other
vendor.

I have P4C800 DLX and Antec case and have noticed it also. It seems to
lessen after the computer was 3-4 old and running continously.

My Antec TruePower supply stunk for about a week. Does it smell like vinyl? I
could smell it as soon as I took it out of the box; I never suspected it was any
other component.
 
Oh Yeah! My Sonata and P4P800D AND Enermax465PE had that new just recently
manufactured smell. I personally thought it was the PSU. Just new parts
heating up.....plastic and all the toxic metals too. BUT. I had'nt smelled
it this bad before or in a long time. When we used to build Heathkit radios,
that new electronic parts smell...........Oh yeah........
