I recently built a HTPC to use as a media server and a HTPC in my home theater. I use to run a media server out of a PII and use XBMC for my HT but that could not handle HD. System Specs: ASUS P5N7A-VM Intel E5200 750gb Seagate HD 1tb Hitachi HD Hec HTPC case 4x 2gb A-Data DDR2-800 Lite-on 4x BR Drive Vista Ultimate: I run Vista Media Center because it is the only thing that supports BR Problem: When I have the system up for an extended period of time, running torrents(I think I am allowed to say that?), everything just gets slower and slower. After I restart everything is fine. It is almost like it is loading up my ram but with 8gb of ram I would think it can handle it. Maybe heat but I have run it with a fan on it and nothing changed. After running torrents for a long time the CPU utilization just gets higher and higher and you can see the download speed get lower too until it just dies. I think it is just something to do with Vista but I can't figure out what is making it happen. It is almost like vista won't dump the ram and it just dies.
