Brand new home built system (all new components unless noted otherwise) running Windows 7 64-bit Home Premium on the following hardware: MSI X58 Pro-E motherboard, Intel Core i7-920 (2.66) CPU, Enermax PRO82+ 525W powersupply, Sapphire ATI HD5670 1GB GDDR5 PCI-E video, 8GB Corsair 1333MHz RAM, WD Velociraptor 150GB 10,000 RPM boot drive, WD 500GB Caviar Black for file storage, Plextor DVD-RW, CoolerMaster case. Older Viewsonic VP2030B monitor, Older Microsoft Desktop 6000 V2 keyboard/mouse. With standard Windows 7 power saving features enabled, the following intermittent problems occur: After the system has gone into sleep mode, the video card provides no signal to the monitor. Moving the mouse or touching keys on the keyboard obviously bring the system back out of sleep mode, but no video signal is received. Unplugging the DVI-D cable from the card results in the Windows sound indicating a change. Plugging it back in, results in a Windows sound indicating the change. This happens when you unplug one end of the cable, it doesn't matter if it is at the monitor end or the video card end - as long as the other end is of course still plugged in. The only resolution to this "no video" state is to reboot the computer with the power or reset button. On some occasions when turning the PC on, there is no video signal. The system boots properly (although the BIOS screen takes about 15 seconds to appear - something MSI says is OK), and can be shut down with the correct keyboard sequence. The monitor runs through VGA, DVI-A and DVI-D, but no signal is ever received so it goes into standby mode. When the computer boots properly, usually while it is still loading Outlook (which is set to start automatically), the screen goes completely blank for 5 or more seconds, then comes back on and the monitor menu indicates that it is running at the correct resolution, and then the video works correctly from there on in - unless it goes to sleep. On some occasions, when recovering from a "no video after sleep mode" incident, everything on the screen has been moved towards the upper left side of the screen. The Outlook window which is normally quite large (80%) and centred on the screen has been reduced in size to about 50% and shoved into the top left corner. Also, the 4 gadgets that normally run vertically along the right side of the screen have been moved up and towards the middle of the screen, one or two of them often overlap others. Things I have done/tried: All Windows 7 updates, All motherboard BIOS updates, All video card drivers and software updates from ATI, Replaced the DVI-D cable, Uninstalled the video card and drivers, and moved the card to a different PCI-E slot, Replaced the video card with another Sapphire ATI HD5450 card (temporarily). Sapphire thinks it's a hardware problem with the original card, but since temporarily replacing it with another card, the problems continue, so I doubt that is the issue. (Plus I have to pay $25 to ship the apparently defective - under warranty card - back to them.) These problems have happened intermittently since the system was built in January 2010 and they seem to be quite random, sometimes not happening for weeks, other times happening every few days. Sometimes the system is in sleep mode for 1/2 hour and it happens, other times it is in sleep mode for hours and it happens (or doesn't). Any help would be appreciated.

It should be the issue of the monitor. I just found that the monitor is for Mac.

Hi Arthur. Thanks for the reply, however, all of Viewsonic's literature (including the link you sent to me) indicates that this monitor is compatible with PC's and MAC's. The literature on the link you sent to me even includes the "Works with Vista" logo at the top. The PerfectSuite software does not work on MAC, which is what you may have seen. It works fine under Win XP, Vista, and Win 7. The Viewsonic support site has drivers for Vista 64-bit, but not Win 7 64-bit (probably because the monitor is a few years out of production). This monitor has worked flawlessly for years, starting with XP-PRO all the way through the entire dismal 2-years with Vista (both 32-bit). Only under Win 7 when connected to this PC have I had any issues. I think it's highly improbable that the monitor is the issue. I have yet to try hooking up an old CRT monitor I have, just to eliminate the possibility.

Hi, just poking around the settings a bit more. Control Panel> Hardware and Sound> Power Options> Balanced> Change Plan Settings> Change Advanced Power Settings> PCI Express> Link State Power Management> Setting. I changed this setting to "Off", and so far, without a lot of testing, the video seems to come out of sleep mode without issues. Not sure if this is the solution....but I'm keeping my fingers crossed. Anyone know more about this setting? All the information on the Internet seems to dance around exactly what it does. Thanks.

Hello Read this , for me it was the solution: http://hardforum.com/showthread.php?t=1515878 Panelpatkany

Wow, that sounds very promising, I will have to give that a try. I've never heard of that before, and it seems no one else has either. In the interim, I bought a new 24" widescreen LED backlit LCD for a very reasonable price, and it has worked flawlessly ever since. When I get a few minutes, I'll have to give that a "reset" a try and see how it works out. Thanks for the suggestion.

Hi again, OK, I finally got around to trying this. I still have to check if that actually fixed it, but I managed to get into the "Factory" OSD screen. I had my system running, disconnected my new monitor and plugged in the flaky old Viewsonic. I then: 1. Depressed and held down the #2 button, then depressed and held down the Power button, 2. Almost immediately the amber power light turned-on, the backlight turned on and the output image from the PC showed up. 3. The On Screen Display (OSD) for all the monitor setting came up (at the bottom of the screen instead of the middle where it normally is), and underneath the Main Menu window in the OSD, along the bottom of the overall OSD window, the word "Factory" appears in the middle between the control button keys (#1 for exit, and #2 for enter). (It's not normally there.) 4. Using the down arrow key on the face of the monitor, I highlighted the "Factory" menu item, pressed the #2 key and voula! there was a whole new simple white text on bright blue background window, which among all sorts of settings included "Factory Reset" (which is the default selection). 5. I pressed #2 again to accept and it was done. All that is left is to do is some user testing to see if the monitor behaves as new. Additional informtion: in the top of the "Factory" menu it reads: "LOVP AU Ver.0.36" I took photos of everything and will post them on my Flickr account. To find them go to wwww.flickr.com, click on the search button, then on the next screen click on the People tab, enter my name and click search. Thanks again for the advice. Tom
