Only use 1 monitor and I haven't changed anythinng..........even uninstalled any updates for past 5 days......rolled back comp 5 days as well, (system restore). No help there.......:( I've been running EnB on this machine 2 yrs or so which is 98% of what I do. I avoid changeing anything if all is working well. Again, I can't think of anything else to try. Thanks for trying to help tough, I appreciate it......:)
