Re: for some reason the monitor has gone blank connected...
Go through your BIOS setup and choose 'Factory Defaults'
This will set the initial video to a low standard that will at least allow about any monitor to come on.
The second system may just happen to be feeding your monitor what it wants to see.

If your monitor is going in Power save mode it can be cause by following reasons.
>Check the data cable going from monitor to your Dell Dimension 4600 Tower is connected properly.The connector will be blue or white in colour.
>If the Dell Dimension 4600 Tower is powering on.
If still in power save mode then try to shutdown Tower and monitor,disconnect power cable from tower and monitor.Hold the power button on tower for 15 seconds.Then again try to connect monitor and check,if still nogo,and if tower has no lights then issue with motherboard or video card or power supply.If possible try connect spare known good monitor.
well first check to make sure the cables are plugged in and not frayed or kinked. then check to see that the cord from your manitor to your tower (its normally blue) is screwed in because if it is not it will have a hardtime finding connectivity
Please connect the cable from the tower to monitor firmly. If this is gone bad, you can change the cable. Please turn on the monitor and connect it to power. You can try to connect this monitor to other computer just to check if it is working fine or not.
open the tower, on the mother board you will find the RAM card approx 6 inches long, take out the card and restart the comp, you should get the beeping sound and the mother board is fine, if no beep that indicates the motherboard has gone bad.
place the ram card properly into the same slot and then restart the computer. NOTE while putting your hand into the comp components always make sure that the pwr cord is pulled out or else you will get shock.
also check the cord at the back of the harddrive should be fixed properly. take it out and refix it at both ends . probable cause is there is some loose connection of the cord or the RAM.
we need to make sure whether its a Tower problem or monitor Problem> Do this simple test> Disconnect the Cable that connects the Tower to the Monitor(while the tower and the monitor are on)> then see if you have any error msg on the monitor screen> if you have someting that says "Chk video cable" or " no signal"
Ur monitor is fine and the tower is faulty> IF not thn ur monitor has gone bad>
is your CPU working properly?
if that the case, your monitor is in need of a service. anyway read this.
this may help you.
reasons for why a monitor not turning on? Reason 1: Wetness The number one reason why computer monitors go blank is - wetness. Believe it or not, when your computer monitor is exposed to humid air, sometimes water can condense and accumulate in the monitor. This causes the monitor to malfunction and go blank. I've had this happen to my desktop PC at least three times before. What you need to do is to leave the monitor alone for some time and allow the water to evaporate. That usually solves the problem.
Reason 2: Faulty Graphics Card The next reason why your computer monitor goes black is due to a faulty graphics card. The best way to detect this kind of problem is to connect up a new monitor to your PC, then check if you have a blank screen. If you continue to have a blank screen, then it's likely your video card is faulty.
Reason 3: Faulty RAM This one is less obvious and less common, but it can happen. You might sometimes get bad RAM modules which prevent your PC from booting up even to the basic BIOS startup screen. To detect this kind of problem is more troublesome, you might need to remove those RAM modules and insert them into another computer.
Reason 4: Loose Connections Another reason why your monitor goes blank is due to loose connections. The connection from the monitor to the mains is usually a culprit, as is the connection between the monitor and the video card. Check those connections before you declare your computer monitor as faulty.
Reason 5: A Short Circuit In The Motherboard And the final reason why your computer monitor goes blank? It's possibly because of a short circuit in the motherboard. This is the most undesirable outcome of course, as you might have to replace your entire motherboard. However, it's possible that this can happen - so keep your fingers crossed and hope it doesn't happen to you. try this. please rate my solution. have a nice day.
Look in the back of the Gateway where you currently have the video cable connected. If there are two connectors, (Side by Side) there than disconnect & re-connect to the other. Your display should come up. Don't be fooled. Most Pc's that have no display on their monitor is not a monitor problem but a computer problem.
Is the green flashing on the tower or the monitor?
If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.
Check for the power supply light at the back of the tower.
Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.
Then connect the cables and check if it is working.
