My Hp monitor has been going to sleep when it shouldn't be. I can be in mid click and the status window in the middle of the screen pops up and tells me there is no input signal then it goes to sleep. The monitor will not turn back on unless I reboot the computer. Up until the other day the computer would turn back on, now it just beeps at me. It gives a series of beeps. Two single beeps than One long beep, it does this 9 times then nothing. The people at hp had me pull my ram cards out one at a time and start the computer but still it beeps.
Is it a laptop or desktop you have no screen?
Most issues are the ram or the caps (if its a desktop) surrounding the gpu chip which store the power to it.
I have one now from a client, a dell mini tower with no signal but havn't felt like messing with it yet.
hello....friends! i am facing this simillar problem.
when i turned on my computer then there nothing appear in my monitor.
and then i hook out the pluug and plugg in the mother board it can get signal but keyboard looses signal then again i pluug the ware in AGP it worked!!!
but this time when i turn it off and i turned back on it showing the previous problem......
so plzzzz help me!!! i dont like to pluug out and replugg the ware all the time!!!! so help fast......
I would suggest we check the Monitor cable.
Seems the computer is working.
Some simple steps to discharge and reset the computer:
Unplug the power cord to the computer, pressing the power button over 20 seconds do not let go, then connect the power cord and power on the computer again.
I would have this issue where I would turn on my PC and everything would boot up fine, except no matter what monitor I used I would they would act like my computer was on sleep. All my lights came on so did my keyboard and mouse but no image. Well my GPU fan would come on but spin at full speed and never back down.............
I had a similar problem. My computer was turning on but i will note that my keyboard and mouse were not getting power, but my headset was. It would start up normally but nothing would show up on the moniter. Basically, what I ended up doing was unpluging the DESKTOP power source and moving it into a straight wall outlet. So try to change outlets. This fixed my problem. Just another option when all else fails.
There are so many things that this can be... start with the simple things .. check monitor on another computer or another monitor on your ocmputer just to be sure. If the monitor can be confirmed good then check the cords, check the ram to be sure it is not loose.. if none of this helps, then you have to move onto hardware issues. The only virus that can harm a computer is out of date far far behind us. There used to be a way the viruses would get into your bios settings and turn your settings up to make your computer run full speed until it burned something out, but that is a thing of the past. Don;t assume it is not the monitor becuase is worked yesterday... electronics are like lightbulbs - they work great until they don't.You glip the switch and nothing, Don;t be that guy that keeps flipping the switch and saying the light worked yesterday. I mean this as a compliment not a dig - the smarter a person is, the more they over think problems and forget to check the easy stuff.
first, check if your power supply has 3volts to power up your motherboard using volt meter. if it has, check your RAM if properly seated or clean your RAM with pencil eraser. if it doesnt, try to check your video card...clean with eraser and re-seat it. check your VGA for loose connection or simply check your monitor by connecting it to the other system unit....
