I just recently starting having an issue with my rendering process completely locking up my computer. Total lockup, where the cursor freezes, keyboard doesn't respond, screen completely locked. It happened while Skyping with my cousin, and I could still talk to and hear him, but absolutely nothing else was responsive. I had to hold the power button to shut down.
This problem started when I tried to render a production. I have since troubleshooted it a bit and I think I have narrowed down the issue to rendering anything that requires the iPad (which I THINK is MPEG4) codec. DivX works fine, Windows Media format works fine, but if I try any of the iPad options or if I try to render to send straight to YouTube, it completely locks up.
Here are my system specs:
Operating System: Windows 7 (64-bit) Premium
RAM: 8.00 GB
CPU: AMD Phenom II X4 840 3.2 GHz
GPU: Powercolor AMD Radeon HD7750 1GB DDR3
I have done an uninstall/reinstall, I have done a repair from the disk, I have made sure all of my hardware drivers/software is updated, I am not running antivirus, I have allowed all exceptions through firewall, I have tried running as and not as administrator, I have done a memory diagnostic test, (which I don't completely trust as my computer has been blue screening randomly with PAGE_FAULT_IN_NONPAGED_AREA and BAD_POOL_DATA errors for weeks even after replacing everything BUT the RAM, but that's a question for another forum), and I have both defragged the drives and cleaned the registry.
It truly seems to be whatever particular codec does the encoding when you format it for iPad devices or YouTube.
Any assistance would be greatly appreciated.
