@Oki You could try ticking/unticking "Enable legacy AVC decoding" in Preferences FileI/O.

With Project Properties - Deinterlacing Method, try "None", although it shouldn't make any difference.

@Oki In your reliability report, Windows is reporting several hardware errors. Can you expand one of them and show it? (View technic...)

@bvideo and @EricLNZ

Thanks for the response. Actually, I ran it again, and no such errors came up so I couldn't expand the " view technic" but having said that, it seems like I'm having no further issues (so far) since I followed some of the tips in this video

Hey @bvideo today after I started new project, it froze after I imported some clips, and then again when I changed the speed of some footage. I closed Vegas via task manager each time. I ran the RM, but there was nothing that came up, but then I realised that I could check out the prior days, so here is the expanded "technic" of the top error you asked for previously. Let me know if there is something obvious that I can correct. Cheers.

Googling livekernalevent probable causes, suggestions seem to be to make sure all your drivers are up to date, there is no malware/virus on your computer and to run in the Command Prompt as Administrator, sfc /scannow and let is scan your computer.

In the Windows Search window, type in cmd, and you should see Command Prompt appear. Right mouse click and run as Administrator. When it opens, type (or copy/paste) sfc /scannow and let it scan all your system files. If there is an error, it will try and automatically correct/replace the file(s).

@Reyfox ok I've run scannow, malware not an issue, and am in the process of updating all possible drives now. will see how all that goes. thanks for the advice. cross fingers it solves it.

@Oki The specific code for that LiveKernelEvent is 141, which relates to a watchdog timer, which could mean some system-level code did not end within a reasonable time, or something in the hardware locked up. There doesn't seem to be a generic troubleshooting process. Drivers (especially graphics), temperature, or basic hardware, like memory, could cause it. Not helpful, but definitely showing an issue that is likely to recur.

@bvideo that's disappointing to hear. Is there ANYONE whose Vegas doesn't have issues?

I've never had or heard of an issue like this with VEGAS. Does this machine pass CPU and GPU stress tests and benchmarks?

@RogerS check my signature.

Signature is just a list of hardware. Is it properly configured? I did a lot of testing when I built my system including modifying inappropriate voltages the MB defaulted to.

@RogerS okay, so how do i make sure it's property configured?

@Oki There are some great online guides that "overclockers" use to ensure stable systems. Limiting voltage and heat is a good place to start.

Since you have an Intel CPU you can try the free Intel Extreme Tuning utility. Run a 10 min CPU stress test and watch temperatures. https://www.intel.com/content/www/us/en/download/17881/intel-extreme-tuning-utility-intel-xtu.html
It's also a place where you can try different voltage strategies before applying it in the bios (UEFI). It possible to only use this utility but I found it unreliable for setting voltage each startup.

Beyond that 3DMark has tests that stress both CPU and GPU which is more akin to what video editing does. It's free to use. https://benchmarks.ul.com/3dmark Try benchmarks and a stress test like Speedway and see if the system has any issues.

There are ram tests but I don't specifically know one to recommend to you.
