I have reacently upgraded my computer with new samsung ssd and went ahead and got windows 8 plus start is back while i was at it. I am really loving both so far coming from vista on a mechanical drive this speed is insane, but on two diffrent occasions when booting to the desktop no icons would load and my start orb would be gone. Once restarting however everything is fine, so just wondering has anyone else had this happen to them and any thoughts on what might be causing it.
