I have a Gateway GM5626 desktop computer running Microsoft Vista Home Edition and it is connected to an Acer flat screen monitor. I have had this system for approximately two years. The system has run without problems for most of the time I have owned it. Recently, the CPU has intermittently had problems communicating with the monitor on start-up. At start-up, sometimes they communicate and sometimes they don't. When they don't communicate, the computer seems to boot up, but nothing is viewable on the monitor. I have checked all of the cable connections and they appear to be fine. In the past when I have run into the communication problem, I have been successful resolving the issue by manually shutting down the computer and restarting it...and the monitor will then usually work on the second or third boot-up attempt. However, today, I have attempted to boot up the computer 10 or more times with no luck in getting it to communicate with the monitor. Does this sound like a driver issue or something else? How should I troubleshoot this? I have though about plugging another monitor in and seeing if it works but I really don't think the monitor is the problem. Thanks.
