All of my GPU Tasks are finishing with in a few seconds with the message "Computational Error". This is occurring with two different projects, Milkyway and Seti. It has been happening for three days. I've performed a System Restore to before this started with no change.

Any ideas?

Why ask here? Computational errors are a project thing, not so much a BOINC thing. BOINC doesn't crunch the work, the project science applications do that, remember?

Anyway, what I see on your host at MW is all exit code -1073741819 (0xc0000005).

See this FAQ for possible causes.

You can also use MemtestG80 and/or OCCT Perestroika to test your GPU's memory.

Looking at your errored tasks at Milkyway, I'd say the first course of action is to try a repair install of Boinc 6.12.34 (just run the Installer and select repair),
then if that doesn't help then reset both projects and see if that helps,

Claggy

Resetting both projects corrected the issue. Thanks!
