My PC goes in Standby mode?

Monitor goes into power saving mode while i'm using the PC or when restarting?

• while i am using my computer the monitor goes into power saving/sleep mode (orange light comes on). i move the mouse, turn off and on the monitor but it doesn't fix the problem. i try restarting the computer but once i restart the monitor goes back to power saving mode, while the computer works fine. If i turn off the computer and leave it alone for an hour or so and try turning it back on the monitor works but only for a few minutes and then does the same thing. how can i fix this?

• Answer:

  Typically this issue is not going to be caused by the monitor itself. You're going to want to start your troubleshooting at the video card level. From the symptoms you're experiencing, it sounds like the card will work for a few moments and after some short usage, will fail. Some likely causes are a) The GPU (Graphics Processing Unit) is overheating, b) The firmware is corrupted, c) One or more other components of the video card has failed, and in an improbable but still possible scenario, d) The drivers installed have malfunctioned. Try a few of these: If you're using a video card and the video card has to output ports, trying plugging your monitor into the other port. Open the case, and if you have a video card with a fanned heatsink (heatsink with a fan) make sure the fan is spinning. If not, verify cables if there are any that go to the card, and replace. If you're using a video card and the computer has a standard output port (usually VGA - a blue colored port) try plugging your monitor into this. Depending on your monitor, you may need an adapter; most LCD screens use "DVI" as it's connection type, and almost every monitor comes with a DVI to VGA adapter. To easily distinguish the two, DVI is typically a white rectangular port, and VGA is a blue trapezoid on the female ends. If none of the above work or you have no additional ports to play around with, try booting in safe mode. Most motherboards will require you to use "F8". To enter safe mode, turn off the computer first. Begin powering on the computer while repeatedly pressing F8 as it goes through the screens and post-check until you see several options including "Safe Mode." If it works fine in safe mode, very likely it is your driver. Logic is key here in isolating the root cause. Consider these If > Then statements: If the monitor works when plugged into a different port on the same card, the issue is the card but no replacement is necessary if you have a second working port. If the monitor works on a standard VGA port from the on-board card, the issue is most likely the card itself or drivers for that card - consider a replacement after isolating the drivers are not the issue. If the monitor fails on a standard VGA port from the on-board card, the issue is not related to the computer's hardware and will be either software related or the monitor or cable (again, not likely). There are dozens of these, and I will not list them all. You'll need to have a logical pattern set up whenever you do any kind of troubleshooting. On a last note, the best troubleshooting step would be to try a completely different video card. It is easy, quick, and can help you isolate the issue in the fastest possible fashion. If you're comfortable with opening up the case (it may seem intimidating but there are plenty of youtube videos to help you build some confidence) then I would make this the first troubleshooting step, possibly saving you loads of time.
