Hi everyone, new to the forum, but would like a bit of assistance if poss. I built a new pc approx 8 months ago, and up until recently has been working absolutly fine. I do a lot of video editing, and have recently got myself a new hi def camcorder from Sony. The type of files that the camcorder creates are mts files. I've recently upgraded my version of Sony Vegas to 9.0 so I can edit the mts files and convert them to mpeg2 files enabling me to author to dvd etc, as I don't have a blu-ray burner at the mo. When I render the mts files after a while my pc just switches off. I first thought it was overheating, so replaced the cpu cooler (which was standard) to a way bigger one, but get the same problem, so I don't know if it is a overheating problem after all. I am now thinking that maybe the pc is just not up to the job, but to be honest would rather not have to buy a new mboard, processor if poss, if there is something that may fix this. Obviously just from a financial point of view you understand. PC spec is as follows: AMD Athlon 64 Dual Core processor 6000+, 3.12GHz 4gb ram 650w power supply Nvidia Gforce 9500GT graphics card I've attached a few screens from Speedfan. First is normal, second is when rendering mpeg and the third is when rendering mts files after 6 minutes. (note the work the processor is doing!) Any help is greatly appreciated. Thanks in advance.

Looks like the CPU overheating, as that's the temperature that is changing when you encode video (which will be the CPU) and it is reaching 79C, which is too hot for a CPU really. Sounds like you didn't install the new cooler correctly, what thermal paste did you use? I assume your PC case does actually have fans installed?
Temp3 is often the GPU. Considering that Vegas has GPU acceleration, I would look at the GPU first...the cooler might be clogged with dust, or it might just have a crummy cooler.
But an overheating GPU will not shut a PC down, if things really do get bad, it will reboot it, forcing the fan speed to 100% either shortly prior or shortly afterwards. Considering Speedfan has picked up a GPU temp and labelled it such (and they don't show up often, but when they do they're usually right), I don't think it's the GPU. Temp1 is a null sensor as it's at 25C permanently, Temp2 is a misread sensor, which leaves Temp3 and Temp as the CPU and motherboard. I think Temp3 is the CPU and Temp is the Motherboard. The relatively high motherboard temperature suggests the case isn't adequately cooled, which may perhaps be leading to thermal runaway on the CPU. Typically when programs like this are GPU-enhanced, the GPU has to do very little work, maybe 10-20% load, thus the low GPU temperature.
