About a month ago, I replaced 6 XP PC's on a 2003 SBS network with HP 6000 Pro Small Form Factor desktops running XP Pro. The machines came bundled with HP LE2001w 20" widescreen monitors. All was well when I set them up, installed applications, did all Windows updates. All was still well when I joined them to the domain. The trouble started - as improbable as it seems - when I installed Office 2010 Standard Open License via download. Now, when the PC's are rebooted, the monitors go black just before the login window appears. It may come back or it may not. If it comes back, it may be red or blue or green. If you power off the monitor, it will often come back on with correct display; sometimes not. I have remoted in to a machine, had their monitor go black, but I can still see the desktop. Replacing the monitor with one from the old PC fixes the problem (if you can call it that.) I have upgraded the video driver and reverted back to the old one. I have removed the PC from the domain and rejoined using //server/connectcomputer. It seems like a video driver problem, but I'm at wits end. Is it possible a setting is being passed from the server to the client and messing with the video? It seems the problem goes away if you login locally, rather than onto the domain, but the problem is so intermittent, it is hard to tell. Sometimes the monitors will be fine for days; sometimes if it goes blank via screensaver it will come back fine; sometimes when you restart, it will be fine. It most often goes bonkers, however, on restart or cold start. I believe there is one machine that has not had Office 2010 installed and has not had problems. Is there something I can check on that versus the others to troubleshoot?
Thank you in advance for your help.
