Quote - This used to happen to me, back when I was so scared of PCs that I still bought them retail, and the latest version of Poser was maybe P5? It would get so bad that Poser would always crash, leading me to suspect a problem with the models I was using at the time (they needed long render times).  Then I opened my PC to find it full of compacted dust, especially in the CPU cooler fins - the load the renderer was putting on the CPU during extended render times was causing it to get hot and the cooling fan to run flat out (hence the noise)- the dust was then causing it to overheat every time I ran a long render. 

Frightening how little I knew about PCs in those days!  I now build my own systems so aren't scared of them any more, and have no dust.  You might also check that the thermal paste which seals the CPU cooler/heatsink to the CPU hasn't dried out and become ineffective.  Pennies to put some new paste on there.

 

A good few years ago for me these days, but I remenber the time when a mate told me had built his own PC and looked at him with disbelief.  In those days PCs were PFM for me - Pure Flipping Magic.

Like a lot of other things I found it was relitively easy when you try and over the years the builds have become even easier.  The dificulty these days is finding the right spec for your needs as there is so much good stuff out there.

The advantage of building your own is you can build to your requirements, one of mine was to have a quiet PC as it is off the floor (to reduce dust intake) and fairly close for easy access to DVD drives and USB ports.  I am really happy with what I ended up with and when I looked at a pre built the closest I could get was about $750 more.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
