Multiple problems all of the sudden:
*Simple calculations use 100% CPU.
*Formulas only work if you double click the cell.
*Formulas dragged down a page using fill handle only return the value of the first cell.
*Memory leak as recent data changes have disappeared.
I ran Norton 8.0 and Avast--no viruses detected. Please help!
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
