Freeman, Sounds like you have a good handle on the OS, I was just being careful. Your problem sounds heat related. When the video comes back, is that shortly after any processor intensive background apps? Virus check, file transfers, etc... You say that a reboot solves this problem instantly. Is that a cold or warm reboot? If it is a cold reboot, that would lean me in the direction of heat problems with the graphics card. When you access the monitor display adjustments, is that during the time the screen is blank? If so, then it definitely is not the monitor. Also, you say this problem just started to happen. Can you relate that with any major software changes, specifically to the OS or Graphics Card Drivers? Just throwing some stuff out there.....

More that likely you have one of two problems: 1) the OS power settings are turning off the monitor 2) The backlight on the Monitor is dying. Just a couple of questions: 1) Can you view the on screen menus, such as brightness, contrast, position, etc...? 2) You say you "Lock" it to the welcome screen. Do you mean that you are just booting up to that point and then sleep or hibernate the PC without a logon? If so, I would check your power settings in Windows. You said that you turn off the monitor and when you turn it back on (after a period of time), no picture. That sounds like the OS power settings are set to turn off the monitor. Right click on your desktop and go to: Vista: Personalize, then Screen Saver, then Power Management, then click on the link: change power settings.... to the left is a link to Choose when to turn off the display. Make sure Vista is not set to turn it off quickly. XP: Properties, then Screen Saver Tab, at the lower part of that window ther is Monitor Power, click the Power Button, then the Power Schemes Tab will give you options for adjusting when the monitor is shut off. If this is not the issue, check cables, try another Monitor, and even make sure the drivers are current for the video card. This is all assuming you have the BIOS set to default settings

Man, I was just saved a lot of grief by this Forum! I just wanted to say THANKS. I have almost the same issue, but was able to narrow it down to my WUSB300N wireless usb card! Once I unplugged it and got off my network the audio plays without stuttering. As far as the root cause, it may be an IRQ request but I sure cannot find it. If I get to the bottom of it I will let the Forum know. Thanks Again "The more complicated the plumbing, the easier it is to plug it up" Scotty
