The 30 minutes tells us it's some hardware issue not drivers or software.
It's some unknown laptop so are you using the canned air monthly? Here I use it the 1st of every month. That way even if I forget one month I catch it the next. Some laptop owners never use it and the dust and such builds up and they need a shop to clean it. As there are plenty of Youtubes on that, I pause here.
This issue just recently started. I have an hp entertainment PC.
I use my laptop for watching Netflix. I have it connected to my tv using an hdmi cable.
Now after watching netflix for about 5 minutes the issue will start. Both screens go black real quick then picture comes back. But it is frozen and making a loud ticking noise through the speakers on the tv. The laptop is then non responsive and will only shut off by holding he power button. The laptop then will not turn back on. When I try to start it back up it tries to start but shuts off after about 3 seconds. After I let it sit for about 30 minutes it will then allow me to power it back on.
It only does this when connected to hdmi.
The things I have tried are:
Higher quality HDMI cable
Using to setting to only use the tv as the display
Tying it on other tvs.
What could my issue be? I'm not very savvy with computers.
