DPMS Off Mode

Specs: Windows XP Pro, Pent. 4-517/1 1/2 G RAM
Recently I had a friend install more RAM (one Gig) to my PC, Acer AST650-U-P5170. Since then, when viewing a YouTube video or viewing a series of photos, after about two minutes or so a blue screen appears and message window, DPMS Off Mode. Then it shuts down completely. Thinking it may be my (old) monitor I replaced it with HP Flat Screen. It still shuts down my PC when viewing videos, etc., but now message window says "Your Monitor Is Sleeping". If I wait 30 minutes I can turn it back on. Everything works perfectly, until I try to view another video, then same problem occurs. Does this have something to do with new RAM or is it something else that curiously began after new RAM was installed?

I assume your system was working fine before the memory upgrade, then 1GB was added & you began having problems, so you bought a new monitor thinking that woud fix it? Interesting troubleshooting technique. Now try testing the RAM.

DPMS stands for dispaly power management system. Some video players turn off screensavers while videos are being played to ensure that the screensaver does nto come on during the screening of the video because this is annoying. This is not always the case with online videos like Youtube. I don't think you problem has to do with the extra RAM you installed. Remove the extra RAM and see if the problem remains. My guess is it will still be there and if so it is not the RAM. I would check the display setting and power managemnt settings. You might google "DPMS Off" and see what you can find. Others may have similar issues.
