I just got an Optiplex GX270 for the office. It has a P42.8/512megs ram. Anyway, the guy booted it up for me before I bought it and everything worked fine. I got it home and it won't boot properly. I turn it on and it goes to the Windows XP screen then the monitor switches to stand by and the screen goes black. The computer seems to be running okay. I hooked up the other computer I was configuring and it boots fine using the monitor so the monitor is fine. The only thing I can think of is it was hooked to an LCD monitor when he tested it and I have a CRT. Could that have anything to do with it. It is incredibly frustrating.
