Hot machine = reboots :(

I work in IT and should know this, but I'm all software now and never got that into hardware...
My PC recently took a poop. I've been using it like I have been for the last 6-9 months, moderate amounts, gaming here and there and encoding AVI to DVD formats mostly. A lot of encoding lately, but say, less than 50 or so AVI files. We're talking the PC is on maybe 6-8 hours in a 2 day span, 3-4 hours encoding (usually not in a row). Then its off for many more hours... so I dont think I've run it into the ground or abused it or anything... and its about a year old.
Anyway, all of a sudden since last Friday, it wont seem to cool down. And when it gets hot, it reboots. This makes encoding and gaming rather difficult.
Does anyone know:
1. What speed my main fan should be at? There's a large # difference between it and the power supply fan.
2. Is my processor (DualCore AMD Athlon 64 X2, 2800 MHz (14 x 200) 5400+) really resetting itself when it gets to 80+ °C? I Googled up that it should not run above that, and stopping and starting my favorite encoding program I can basically time when it will happen. CPU 1 is ahead of 2, but eventually they both get so high (upper 70s) that the CPU entry raises with them and, blip, reboot.
I'm getting all this data from Everest, here's a snippet:
3. Will reformatting/loading WinXP solve this? Can a virus cause this? NOD32 says my HD is clean, and its defragged nicely... so... bad fan?
Of note, my case doesnt feel hot. Either side, or the back. In fact it exhausts out pretty cool air from the side vents.
Anyway, advice, suggestions, links, etc... would be greatly appreciated. I will post entire Everest log if that will help.
(and a few minues later)
Here's an example of the failure of cooling (I'm assuming):
The previous snippet I posted was right after it rebooted, booted up, and I launched Everest to take a snapshot and then got online and opened Firefox + this site open, and posted the message.
The above snippet where its cooler is after all that, and while I sat and typed the first message. As you can see, its much, much cooler.
Browsing, MS Word, etc... none of that spikes the CPU like gaming or encoding, so no problems there.
A friend did just point out that my GPU is still running quite hot. Bleed over making the CPU overheat? Bad fan on the GPU or dust in there causign this? I have not opened the case to clear out the dust or watch the fans (yet).

You might want to look into a cheapish aftermarket HSF even if the fans sound normal. If you're doing CPU-intensive work (which video encoding is) you're probably taxing the stock HSF a little too much as it is and your CPU is probably getting high load temps anyway. $60 gets you this which is an awesome heatsink all around, and looks like it's compatible with your socket.
I also note that your PSU fan seems to be running high. 7600 RPM is pretty fast unless it's a sub-80mm fan, which is unlikely. This, combined with shutdown issues that may or may not be heat-related, lead me to believe that your PSU could be dying. Alternatively it's just not getting cooled down very much by hot air from the case, leading the fan to work overtime trying to keep up.
As for the GPU, that's going to vary too much to diagnose. Depending on what graphics card you have it may be getting intake air from inside the case like your PSU is, and if that air is already hot from a borked CPU HSF or case fan the GPU isn't going to get much in the way of cooling. I do know that most high-end graphics cards are built to take high temps in the first place, they run hotter than CPUs generally. And an overheated graphics card won't shut down your whole system, you'll start to get screen artifacts first, and if it gets really bad you'll have some kind of display crash or a BSoD.
When you boot it up with the case open to check the CPU HSF, see if the GPU gets cooler or the PSU fan slows down. If that happens it's an issue with some other heat-generating component, which is almost definitely the CPU HSF. It could be motherboard heatsinks but unless you have something like a 680i chipset (you won't since you have an AMD, I could fry an egg on my mobo heatsinks) those don't throw off a shitload of heat.
So, yeah. It looks like a problem with the CPU heatsink, and considering how you use your machine I'd recommend replacing it with a better cooler rather than trying to fix the stock one. The upshot to that is if you pick the right cooler you'll be able to use it on future builds, too; that Zalman will work on the current Intel socket too, which should still be in use for the next few years.
First thing you should check is the thermal compound on your CPU heatsink and clean all the fans out in the system. Your motherboard runs pretty warm as well. Do you have any ventilation around your tower to allow for circulation of air?
Is my processor (DualCore AMD Athlon 64 X2, 2800 MHz (14 x 200) 5400+) really resetting itself when it gets to 80+ °C?
Definately a possibility, 80 C is dangerously high for almost every CPU i've ever heard of.
All the previous advice given is good - clean out dust, make sure all the fans are working/seated correctly, nothing is excessively blocking airflow, etc.
It is a stock machine. I've also applied Arctic on a previous computer, so familiar with that. I'll pick some of it up (if I can find it locally), as well as clear out the dust/watch the fans.
Thanks for everyone's questions and answers and getting me pointed in the right directions.
