pvrx2 reboots PC when tuned to local NBC affiliate

[Jon_J]

I'm a newbie and have been reading and following instructions/wiki to setup GB-PVR
I use OTA antenna only, (no cable or dish).
There are no analog channels here anymore, so I only use the Digital side of my Hauppauge HVR 1600.

When watching live TV through the pvrx2 app, I "seem" to have no problems with most of the local TV channels except one so far.
If I tune this channel, it will play for a short time, then will freeze up my desktop PC. (mouse and keyboard froze up too).
It emits a stuttering sound like a diesel truck idling, then my Computer reboots itself.

I think this same situation has occurred when using WinTV-6 and/or WinTV-7

I have a Hauppauge HVR 1600 PCI card installed. This is the only add-on card in this computer.

My PC specs are as follows: (new computer as of last week)
Windows XP, service pak 3
Intel DG31PR desktop motherboard with Intel Core 2 Duo E7400 2.8GHz processor.
2GB 800MHz PC6400 RAM.
Onboard graphics - Intel GMA 3100, 128MB memory, Intel G33/G31 Express Chipset family.
2 SATA HDDs 160GB and 500GB

I'm attaching the log directory in a ZIP file. I'm not sure which logs need to be looked at, so I copied the \Program Files\Devnz\GBPVR\logs\ to my desktop and zipped it up.
EDIT: I forgot to mention, I'm using GB-PVR v 1.3.11

If your PC reboots, then its most likely either some driver problem, or some other system instability or compatibility issue with the components in your machine.

The GB-PVR logs dont show anything useful for this type of problem.
