That can be a very difficult problem to troubleshoot given no apparent issues in your HijackThis LOG. Additionally, you appear to have good coverage against many common malware vulnerability issues - AV (hopefully with current definitions), anti-malware, and firewall. However, such issues can be easily over 50% hardware related:

Where to start? Are there no messages that might provide clues?

Does it occur after some passage of time or is it fairly immediate?:

• It could be overheating issues (CPU and/or video, poor or inadequate airflow or cooling from fans/heatsinks).
• It could be your PC power supply or household power fluctuations (may need an 'uninterruptable power supply' - UPS device).
• A RAM chip could be flakey or your motherboard is now defective.
• There could be bad spots on your hard drive causing corrupted paging issues or the drive is slowly showing signs of failing.

its fairly intermediate and unpredicatable. i hope that helps. =/

Read the first 5 to 10 Google links that I gave - that should be pretty eye-opening. An intermediate time frame may be more likely indicative of heat buildup issues (cause and effect).
