It's a shame the make, model and connections are missing here.
The screen keep blacking out for a second or two. It isn't the monitor or hardware because this NEVER happens when I'm on the Metro Apps page. - Bizarre. I've been through to Task Manager and tried to cull everything that didn't look necessary. Didn't work. I've even done a "Restore" - no success either. The blanking seems more frequent when I start using the computer and after about 1/2 hr on occurs occasionally. I stress that there is never, ever any blanking if I either go to the Metro Apps desktop page or a metro app itself.
Has anyone a suggestion what might be happening?
