Check the cable

by ashij In reply to monitor want turn on?

Hi! runningbear,

You probably have checked this, but have you checked if the power cable for the monitor is working? ALso check the signal cable, sometimes, one or two bent pins might cause this problem. I guess, you have already tried hooking up to a different computer, so that rules outany problem with the computer itself. Hope this helps.

thanks for your reply ashij,yes i have checked the monitor with my computer it work's fine.i dont understand what happened,all i did was reformatted the hard drive and reinstalled win xp home,and the hard drive works on my computer ,boots up just fine,it has to be something wrong with the motherboard i think.because i have been to this girls house befor cause she had problems with this computer befor,the first thing i seen was that the computer wasnt reading the ram right,its a 256ram and it only showed 194 when you click on my computer and go to properties it shows the ram installed,i put the ddr in my computer in my computer and it showed a 256,strange.but like i said the monitor is good.i even hook her computer to my monitor still the monitor want turn on.thank you,any other idea's?

62MB on-board video ...

by OldER Mycroft In reply to Monitor not working.

194MB + 62MB = 256MB.

What you are seeing in the RAM reading, is what is left after the on-board video has taken its share.

Usually on-board video can take UP TO a certain amount (but it has to leave enough for the OS). The upper limit could be anything up to 128MB but that wouldn't leave enough for the Windows system. Also while you are reading the RAM within Windows, the system is not actually DOING any graphically intense work, so chances are the video has only stolen 62MB (as opposed to 64MB).

Does your monitor have twin inputs ? ...

by OldER Mycroft In reply to monitor want turn on?

Using the monitor's own on-screen menu display you will find 2 inputs: Analog + Digital.

Depending on which output you are using from the graphics card (VGA or HDMI) - you might need to alter the input on the monitor or the on-screen menu.

Why is the monitor daisy-chained and not separate ?? ...

by OldER Mycroft In reply to Monitor not working.

Why are you running the AC Mains power for the monitor through the power conduit for the PC ?

Try running the monitor AC Mains straight to a power outlet on its own. - The power throughput from the PC may NOT be working.

Some throughputs have rocker switches that simply "GO" - the Single Pole Single Throw still 'rocks' but doesn't make or break any contact anymore.

I'd be interested to know what sort of PC this actually is.

OK - Now I am getting confused ...

by OldER Mycroft In reply to Monitor not working.

In an earlier post you said 2 things:

#1 - "i can not ajust anything because the monitor will not turn on when i push the power button on the computer"

#2 - "all monitors will click on as soon as the computer starts booting up,but thats my problem,when i push the power button the computer turns on but the monitor never does"

That was when I inquired why the monitor was getting its power from the computer and not from its own AC Mains source.

If the monitor is now plugged into its own power source (NOT via the PC), can you now power-up the monitor and access its on-screen menu?

The rocker (On/Off) switch is located at the rear of a PC, right beside the socket where the AC Mains cord is plugged in. If the PC also has a further power socket for plugging the monitor power lead into (so that the monitor powers on when the PC does) - BOTH power sockets often have their OWN rocker switches. Clearly if the monitor power rocker was switched to Off, then the monitor has no chance of powering-up when you press the front mounted power switch for the PC.
