This stuff rarely happens, but when it does I simply restart my PC then it works fine. But today after several restart attempts it seems to be stuck.
I tried removing the video card then switched to onboard video, same thing: The PC runs, (there's power and fans are working) but the monitor is stuck on power saving mode (blank screen).
Is this a monitor or PC problem? Any ideas what might be the problem?
I'm Windows 7 btw.
It is more likely that the video card is not outputting the display or the resolution is beyond the montitors capability, than the monitor has somehow gone into power saving mode. Then there is a big twist in the question, because switching to the onboard should have tested for the video card being the problem. Unless , you have No Post At All. . Does it seem like the computer goes ahead and boots up without vision? If you shine a light on the monitor can you see anything? Does it seem like the backlight is bleeding through and on, and that it is just the lcd pannel that is dark? – Psycogeek – 2012-03-05T08:54:23.997
I'm having a similar problem with one of my computers. My suspicion is that the monitor is not reporting its "plug&play" info correctly during startup and so the video adapter is using the wrong display resolution. – Daniel R Hicks – 2012-03-05T12:25:13.100
@Psycogeek I have tried using VGA cable instead of DVI. I have also tried a using smaller monitor. Same problem. The PC doesn't seem to send any output at all. I do not see anything in the monitor, only it's blue light flashing (which means it's on power saving mode). I am not sure if the PC is going until windows, I do not see even the BIOS screen. It's just pure black right from the start. – IMB – 2012-03-05T12:45:53.620
@IMB ok that confirms more things. If there were "beeps" from the motherboard would you have heard them? (is a beeper hooked up, do you hear the bios Ok beep normally) . Have you changed any aspect of the system lately? added ram, adjusted bios settings? If you could provide a better History of the computer starting to fail, any other noticeable problems. Right now I would put you back into the "build" state. that one of the 4 majors is just not working correct. MB , PSU , CPU, RAM, Video. If you cleared the CMOS, did you have any special settings, or would it work ok at Default settings? – Psycogeek – 2012-03-05T13:22:01.357
@Psycogeek I do not hear any beeps. The funny thing is I do not remember hearing any beeps at all on normal conditions. What I hear is a "tick". There is one "tick" sound before and after this problem happened. This computer is only 6 months old and like I said this has happened before (rarely) but a simple restart usually fixes the problem. I did not have any changes in the hardware or settings. All is same old from the beginning. – IMB – 2012-03-05T13:32:29.147
BTW, one of my restart attempts recently have worked, I saw the bios screen but then Windows asked if I want to run Startup Repair or Start Normally, I chose to Start Normally but I never reached Windows so I restarted again and then original problem was back. – IMB – 2012-03-05T13:33:28.210
I probably would have wanted to hop into the bios, if I got it viewing. They often have some hardware monitoring in there, and it gives you a opportunity (which I guess you had anyway) to check the monitor thing, and or connection. We would need a lot more information about the hardware? Bios or Boot Cd/USb thing , any possible way to get some views of temps, voltages, settings, or to even "downclock" the system temporarily so you can limp along and check more aspects of the hardware and figure out what might be the cause. – Psycogeek – 2012-03-05T14:11:12.860
^ and I am not trying to imply anything, still not enough info. The monitor going out when the video device is fired up , or even if the bios or system has the Int/Ext display priority thing, the video going to the other device etc. – Psycogeek – 2012-03-05T14:16:40.167
@Psycogeek Ok, I tried to re-seat everything again and suddenly it works. The thing is, is this still an indication of dying hardware? Since this is only 6 months old, it's kinda weird that I have to re-seat stuff. I usually do that only in old computers. – IMB – 2012-03-06T11:13:18.303
Hey, don't look a gift horse in the mouth! – Daniel R Hicks – 2012-03-06T12:36:48.670
@IMB not nessisarily dying, there are so many adjustments, minor tweaks, settings, that can change things slightly. – Psycogeek – 2012-03-06T15:01:16.333
