PC has a burning smell, and possibly overheating?

About a month ago I noticed I had some mild artifacting in my computer (at the time I think the temps were around 48-49d under load) and so I opened up my PC and gave it a dust cleaning, it was fine after that and running around 38 to 42d.

Then a few days ago I got a new stick of RAM (DDR400 1 x 1 Gig Antec with heat spreader, bumping me to 2gigs) and once I plugged that in it seemed my computer jumped in temp. First it was around 45d idle but I noticed it slowly growing, until it was around 50d idle and up to 56d+ under load, and it wouldn't be long before I noticed my graphics card artifacting once again, even more than before. I removed the 1 gig stick and tried using dual 512's in it's place, but after that I instantly noticed a burning smell. I immediately removed the two sticks and currently just have my original 1 gig in the PC (dual channeled)

The burning smell seemed to be coming from the PSU, but I'm not sure. When I checked the RPM with SpeedFan it showed Chassis going around 3000+ RPM and Fan 1 (I guess this is the PSU?) going at a little over 1160 or so.

If any other details are needed, just ask, I'll be taking this computer into the shop tomorrow so any help I can get before then is greatly appreciated! Also, I do live in a house with no central air/heating, just window AC's, so the temp in here is never cool, but the computer itself is next to a AC unit.🙁

Specs:
Motherboard: ASUS A8N32-SLI Deluxe
CPU: AMD Athalon 64 x2 3800+
GPU: Nvidia 7900GT 256mb
RAM: 2 x 512 dual channel Kingston

Last checked current temps:
Mainboard: 44d
CPU: 46d
Core: 50 - 55d
GPU: 50- 53d
 
Yes I see it spinning and I feel a very very slight breeze. I've got my PC on now and the temps are this..

Mainboard = 41c
CPU = 37c
Core = 35c
GPU = 47c
 
If you have the computer's case open, also check the CPU fan and the video-card fan to confirm that they're running and don't have wires snagged in them or something.

Welcome to the Forums, I hope it's nothing major 🙂
 
I have a side-window, and I can see the CPU fan going as well as the fan on the video card.

Right now the GPU just seems to be making a lot of heat, could this be bad circulation? I only have one fan (in the back)
