I am having this problem with DVD Shrink, everytime I try and encode movies, my PC reboots or my desktop including the mouse cursor just freezes. I thought this might have been caused by the memory latency settings or bad/old drivers, so I installed the latest drivers for my video card/DVD drive and motherboard. I updated the BIOS and changed the latency settings according to Corsairs recommended settings. I also thought this might be caused by CPU overheating so I've installed a Thermal Take Silent Tower CPU cooler with Heatsink/heatpipes and 90mm fan recently. I have 2 80mm fans, one's blowing air out and other blowing air in. I still can't figure out why the PC reboots or freezes while I'm using DVD shrink. I am using: Gigabyte GA-8IG1000 Pro-G motherboard Corsair 2x512 XMS TWINX3200C2PT, Dual Channel Pentium 4 3.2 CPU ATI Radeon 9200 128MB Graphics Card Pioneer DVR 108 DVD Drive Has anyone else had the same or similar problems with DVD Shrink and can someone pleeaassee tell me how I can fix this problem.
