Hello all, the details of my system and BOINC installation are below. I'm using Sophos Endpoint Security and I have automatic updates enabled for Windows. The Intel onboard display adapter drivers are up to date.

In a nutshell: BOINC used to run SETI@home for months on end without ever causing any problems (I never had to boot because of BOINC), but after I went and updated BOINC in August my screen started to freeze completely every few days. When I'd come back to the office in the morning, I might find the screen frozen.

The latest BOINC update in September (7.8.2) made it happen less often, but it still happens every now and then. The basic thing that changed on my computer was the BOINC version, not any other resident software or my computer-using habits.

To be more specific, the whole computer isn't frozen, it's just the screen. The computer is still responsive via network, e.g. it answers when I log on remotely using TeamViewer 12 and asks me for my TeamViewer password - but then all I get on my remote screen is the frozen SETI screensaver. Sending ESC or CTRL-ALT-DEL doesn't do anything (sent locally or remotely), and the mouse cursor isn't shown either - it seems like both the keyboard and the mouse are not being polled. But behind this impenetrable wall of not taking orders, the computer is chugging along.

This is extremely annoying because hard booting with power off/on, the only thing that seems to do the trick, causes my RAID1 array to check and repair itself for hours afterwards, making my computer slow as a snail to use for anything I actually need to do.

Any remedies, please? I wouldn't want to get rid of BOINC and SETI@home after about ten years of no problems...

Curious, as the log does tell it's detecting user activity and suspending computing and networking, then resumes networking and then... Is it resuming computing after these log entries?

If it's the frozen screensaver that prevents using the machine you could try not running the screensaver. Maybe a bad driver update broke it.

The problem is intermittent. Most of the time BOINC suspends fine when I touch the mouse, sometimes I find the screen frozen when I turn the display on.

I might add that there haven't been any driver updates for the on-board display adapter in years, the latest was way before this problem began.

Ok. It could be some updated Windows component that together with GPU driver freezes input/output. Worth trying, if only so that you can tell it wasn't that :)

Any chance the machine is overheating?

No, it's not an overheating issue... the fans are whirring away like they always did, there's no dust buildup inside to speak of, and this is an office computer with nothing exotic like a dedicated GPU - just a plain on-board display adapter with the latest Intel Q45/Q43 Express chipset drivers (dated 4 Oct 2012) that worked fine with BOINC/SETI@home until I updated BOINC.

It happened again... once more it's taking hours of working at snail speed while my RAID1 array checks and corrects itself... Now I have switched to the basic Windows 3D text screensaver, we'll see if that ends the screen freezes.

Do you remember what BOINC version you had before you updated it? That is, which version worked ok?
