Topic 220789

I'm running 3 GPUs in my system and it's crashing quite often - sometimes one card stops working, sometimes the keyboard becomes unresponsive too, but usually the display stays on the screen. It's usually the same card that stops working if it's just one that stopped, but today it's two of them. I suspect the power supplies are not stable enough and I have better ones on order. But today I noticed 18 (!) Windows 10 notifications saying:

Application has been blocked from accessing graphics hardware. Application hsgamma_FGRPB1 has been blocked from accessing graphics hardware.

Does this mean anything to anyone? A google search just suggests checking drivers, RAM, etc. I know all of that to be fine. It's a fresh install with the latest drivers and Boinc and updates. Memtest has tested the RAM as ok. Virtually nothing else on the system but AVG and MSI Afterburner (to control GPU fan speeds). They are not overheating, I keep them below 70C. They're all connected to one 4 way riser with USB leads.

Sounds like your anti-virus is being overly sensitive....if so just exclude the Boinc directories from the a/v stuff. Most of the time it's false positives and any real problem will try to escape the Boinc folders and get caught.

I'm not sure how to find any

I'm not sure how to find any history in AVG if it's been blocking things, but I would have thought something would have popped up warning me.  I've added the exceptions for "program data\boinc" and "program files\boinc".  Is that enough folders or are there any more?

Nope that should do it.
