I mentioned elsewhere about this, and thought I'd fixed it by removing Malwarebytes Premium but I haven't. It's a problem described on the internet as the green bar of death. Some people suggest poking about in the registry but given the circumstances I think if that fixed it it would be a "bypass" rather than a cure, which I'd sooner not do. Other than that, I've tried some of the better and ignored some of the more stupid suggestions.
So the symptom is that randomly my computer will stop being able to access the WD NAS shares, which hangs Windows Explorer and obviously if I am on a Word doc which is on the NAS it won't save. If I leave it long enough (usually 10+ minutes) it always completes whatever is blocking and carries on like nothing happened.
Task and Performance manager don't show any over committed tasks or resources.
The network is still fine and I can continue browsing the internet. By default I use a wired connection but it happens on the WiFi too.
The NAS is fine as I can reach it from other devices on my LAN and from outside to read and write. I've run all the diags anyway and all is clean.
Interestingly, I was on a TTY session to my Pi (also on the LAN) when it went earlier, and the TTY session remained OK. Before it failed the other day I had set up a continual ping to the NAS and this continued running when it had failed.
I've removed all unnecessary hardware and USBs from my computer and started in Safe mode with networking but still had the problem. I have re-seated most of the power and disk cables and checked the fans and cooling.
I've run Windows, Windows network and disk diags (even though the SSDs report there is no need) and re-installed the network driver. The only likely stuff in the event logs is likely to be a result of the hang not the cause. I've changed the disk which the system pages to.
I haven't thought to try to connect to any other network devices but I suspect they'll be OK - but I don't think it is problem with the NAS. The problem is once Explorer has hung you can't open another iteration of it.
I went back to an image of the C drive from some weeks before the recent updates (one of which seemed fairly major) and still had the problem - though it may have re-applied the update without me noticing.
I am pretty sure that rebooting doesn't fix it, but I need to recheck that, especially a complete shutdown and reboot ( - if the latter is so then I guess its hardwsre). Nothing about the machine has changed - i.e. no new hardware.
It can go for a few days without a problem, or can happen two of three times in a day (I use my PC a lot!).
I have two things left to try which are to go back to an image from the summer and prevent it from loading updates (which isn't desirable but needs must) and take out each memory stick in turn to see if it is one of them. I suppose the last option is to put a clean Windows on it but that seems excessive.
My feeling at the moment is that it is a Windows software problem, maybe with the protocols which communicate with the NAS, or maybe some internal problem which slugs the task which Explorer depends on. I guess putting the old image on will prove that (or otherwise).
Anyone got any other ideas?
