I just got an XPS600 a month ago , my monitor (2000fp) had been going into stand by mode randomly ever since. I have to do a hard restart to get it out. The PC is still functioning, because I can start and stop music using the keyboard even though the monitor is blank. It was used for a year beforehand with no problems, and my 2nd 2000fp from another PC gives me the same results on the XPS600. Ive set all of the power options to "Never". Ive reseated the graphics card (7800gtx). It seems to happen more often (almost always) when I connect to sites using Java applications.

Thanks in advance for any clue as to what I can try.
