After several months of searching for bugs in Windows or the TV software,
I finally started checking the BIOS. One of the below entries (maybe both?) causes the problem.
PCI Delay Transaction
P2C/CP2 Concurrency (thats not it exactly, but similar, sorry I forgot

I think those two settings may conflict with one another? Or maybe one or both should be disabled or enabled..........sorry I am not the most technical guy but I would like to figure out how or why this happens.....it's cool that I fixed it but it seems kinda strange that I don't really understand how I fixed it.
thanks for reading this and any help you can provide.
