My Windows 7 PC is set up to suspend GPU computing when the computer is in use. A lot of the time, when I return to it after the GPU has been running, the screen becomes frozen. Music isn't affected, but the only way I know of to fix it is to reboot.

I'm using a 1.5GiB GTX480 and Core i7 2600K at factory settings and 16 GiB RAM. My other BOINC projects are FreeHAL@Home, rosetta@Home and The Lattice Project, but I'm willing to change or remove projects as long as I still have FreeHAL, at least one CPU-intensive project and at least one GPU project.

BTW, I haven't experienced this issue when playing World of Warcraft or League of Legends, so I don't think it's purely a hardware issue. However, the card was refurbished when I bought it in mid-2011.

You are clearly able to complete GPU tasks, so there probably isn't a GPU fault.

Both rosetta@Home and The Lattice Project are troublesome. Both can use exceedingly high amounts of system memory; Rosetta uses increasing RAM as tasks progress (several GB's each) and the Lattice project can use up to 8GB per task! I've had trouble with both projects in recent months.

FreeHAL is a non-CPU intensive project, which I also run. I haven't experienced any issues with it of late.
Another non-CPU intensive project is WUProp@Home.

There are plenty of other CPU project that behave themselves much better:



BoincSIMAP is quite painless, as are most WCG projects, and the Malaria projects. There's also a few good CPU based Astronomy projects...

I suspect GPU-Grid doesn't like being suspended and restarted very often (complex code, lot's of stuff going on.. might get the GPU driver into trouble).

Reason I say this: I had been running POEM fine, and when POEM is dry (often recently) the box has been running GPU-Grid fine. However, when I get occasional POEM WUs (lasting not very long) BOINC switches to these (GPU-Grid is only backup project), finishing them, and switching back to GPU-Grid once my local POEM queue ran dry again. In these times in find my PC with an unresponsive display much more often than usual. It's often accompanied by a GPU-Grid computation error.

Does LAIM off make any difference?

Probably, didn't try yet.. it's not that common :D

(Just to be clear: I'm leaving all suspended apps in memory. If I didn't, the lock-ups upon task-switching would probably disappear.)
