Hello,
EDIT: just happened again, caught, this time while listening to audio in chrome, and caught chrome not responding in the task manager just before the lock-up. So it seems to be chrome, any ideas for a fix?
I purchased my Optimus IV 11 months ago, currently running Windows 8 (not 8.1), it has been running very well since, negligible problems, however in the last 14 days it has locked-up randomly on 5 occasions. Each time this has happened I've been watching something in Chrome, or had Word open and the computer idle.
I've been through event viewer thoroughly, and nothing stands out - there are no errors or critical events logged at the times of the crash, only after the hard reset (e.g. unexpected shutdown). The only thing with any pattern is a DHCP address assignment error a few minutes after the lock-up, coinciding with all the recent crashes, though it has happened with no crash in the past.
I had heard that idle maintenance can cause problems, so disabled that in Task Scheduler, however it has frozen once since doing so. I've had Task Manger open a couple of times when it happened - nothing unusual showing at the time of crash, no CPU or Disk over-use, and system temps are fine (Speedfan - 40 to 60C).
Typically I'll go to click something after a period of inactivity, it doesn't respond (on the last occasion this was Netflix streaming), then you get about 5 seconds where you can do something (i.e. grab a look at Task Manager) and then it totally locks up, but the mouse can still move. It's unresponsive to any keyboard input (including CTRL+ALT+DLT) and a hard reset is the only option - even tried waiting 30 minutes on one occasion. It first happened when I fell asleep and left a youtube livestream running.
As far as I'm aware all of my graphics and other hardware drivers are up to date - not sure the best way to check this. I use the in-built Windows Defender for antimalware etc and have malwarebytes to scan every now and then. I don't have any other unusual software installed.
I'm baffled and quite worried, as this is a fairly major problem - would greatly appreciate some insight or potential solutions if anyone has any.
Many thanks,
Rahl
