PC disease diagnosis needed!

I am certainly considering upgrading to a SSD, as at present it is just a 7200 rpm hybrid, but for it's main purpose of music streaming, it hardly seems worth all those beer tokens. Thanks for the Sysinternal prompt - I am just now going to give it a whirl.
Maybe it doesn't like the music you are streaming. :) Seriously, how old is the laptop? I hate to say it but perhaps the cpu is just dying. I have had that happen to me.
Hope you figure it out.

GPU heating ... doesn't that usually mean cryptojacking? You could try booting to safe mode and see if it goes away - if it does, then something is using the GPU and crypto is a good bet. Reinstalling the OS is the best way I know to get rid of nasties like that ... Or it could be that the heat paste on the GPU (do they use that on lappies?) is breaking down and it just doesn't have enough cooling any more!

The plot thickens! The machine can still crash sitting idle, doing nothing, with a blank screen saver showing. I guess I bin hacked! My latest experiment, I found a tvnserver.exe in the startup folder, but I uninstalled Tight VNC a several months ago when I went to Win 10 Pro and could use MS RDP (sheer idleness so I could change the music with my Windows tablet from my armchair). Anyway, it is now disabled, and am currently awaiting the crash...

My entertainment laptop which used to be my mainstream machine, an Acer Aspire 19" running Win 10 Pro, had a problem of an inadequately cooled GPU. In the summer it would frequently just lock-up - frozen screen, nothing working, so a power switch long press needed. It always happened when the GPU was working hard, but the CPU temperature never went above 78°C - well within bounds for a Core i7 - and usually ran at around 65°C. Now, it is happening at modest room temperatures when the GPU should be doing nothing - static screen, no apps running, just either Edge or Chrome streaming music over the headphone socket, with HDMI disabled. I use Malwarebytes Pro, free courtesy of my bank, and when I installed their Browser Guard it found a couple of dodgy extensions in both browsers, which it deleted, and everything was fine for that evening, but the next day the problem was back. It rather looks as if I've been hacked. Unfortunately, being an older machine, Task Manager does not show GPU activity like it does on my newer laptop. Does the CP hivemind know if there's anyway of finding what is accessing the GPU - and, more importantly - how to stop it? Pretty please - it's driving me crazy! :-\
Are you sure it's not something like a bad/clogged fan going to your GPU?

Just noting of course that the CPU and GPU are two different things. And in two different places. Brief search also suggests that GPUs have a higher failure rate than CPUs. So if the GPU is on the edge of a failure then running hotter but not hot, might push it over the edge.

I am replying to my own message, having, I hope, resolved the issue. I stopped tvnserver.exe loading at startup, and all now appears to be well - it ran last night quite happily from late afternoon to 23:00. I am not suggesting that tvnserver.exe was the direct cause of the problem, but it may well have been letting something else in that was burning up the GPU.

The heat sink is a thick copper bar, as explained above, and it handles both CPU and GPU. If it were a blocked/failing fan then both would overheat.
Still could be the paste bonding the GPU to the sink went dry/bad. That used to happen to me on old CPUs a lot. If the GPU routinely ran hotter than the CPU then I could see the paste decaying at different rates. Anyway, just a thought. Most of the time I face catastrophic issues with my PCs it's either a hardware problem or a Windows update. :)

yikes, re-installing the OS is a major pain in the butt and usually not necessary to fix PC problems. One effective way of discouraging hackers is to setup am account to access windows and have it password protected. Then change the password every day. It's a little job, but it really messes with the hackers ;) Another way is to not have your computer online all the time. If you are set on scanning, try the spybot search&destroy engine. It's pretty good, and it does effectively remove a lot of hacker hooks, so running it every day can really cut down on unwanted code running on your pc.

Not really: for me it's about 1/2 hour, plus updates to apply - I create a clean image when first installed with all needed apps, and that's how long it takes to do a test restore. It helps if you keep all data on a different drive as well ... Virus, malware, hardware failure, ransomware: stuff the lot and reload clean!

The problem with that approach is that you then have a computer with an out-dated build online updating which makes it highly vulnerable to bots looking for computers that insecure to attack. The only way to keep that remotely secure is to have a windows cd you can fresh install from and all the updates on dvd or something so that you can install them all while the computer is kept offline until it's security build is fully up to date. That is a tricky measure to implement since you tend to only download what you need for your hardware build, so if that changes, all the updates that go with that new build are now slightly different than they were for the old build. In other words, the most secure ways of re-staging a PC can get pretty complicated over time. You are very correct about having the data on a different drive. I have never regretted doing that.
