I was in your problem 2 days ago, and the VGA card was not connected proparly, I opened the case, connect the Display adapter well and start, and hey everything is going to work again.

It sounds like your video card got jarred loose, or is bad.  Try reseating it, if that doesn't work, you may need a new one.\n\nBy the way, the computer itself comes on, right?

Why not check the simplest thing first. Go to Control Panel and select Power Management. Check the entry Standbymodus - is there a time defined? If yes, set it to none or never.

On the desktop right click then go to properties.  Under screen save go to power stettings.  Just turn "shut down harddisks, sleep, and hibernate" to never

Your monitor isn't on or plugged in properly to the computer.

either reinstall your drivers, or buy a new monitor...\n\nwas there a power surge, or did you buy the monitor from another source?  many instances of this occurrance is the monitor is faulty and needs to be repaired/replaced...

It´s ´probably just going into "Stand By" or you need more time in your energy savings config. \n\nGo to Start> Control Panel> Display >Screen Saver> click on the energy saver button> there is a combo box that says turn off monitor change that to 10 minutes or 15 whatever you like.\n\nThis gives you more time to levae the computer an d the monitor won´t go off.\n\nhope it helps

Your screen has gone to standby to save power, just wiggle the mouse or click. and it should come back. You go into your computer options and change the preferences so it will not do this as much or not art all

check your monitor power options makes sure that hibernation is disabled and also check the power schemes settings and adjust accordingly.

Press alt+F4.\n\nOr just activate screensaver or set powersaver option to something very short time so that monitor goes to powersave.

Well years ago when monitors were as big as houses and as heavy as one (remember those?) I had one that did this. The power button went bad.\nKept using it for a couple more years with a wood screw in there keeping it on lol! It was one of the first 17" or something, that was pretty cool back then lol!\nSaw your question and this came to mind :0)\n\nThe link below is for the drivers that might help you, sounds like a hardware problem though......

It could be your video card has died.  Or try a new monitor cable.

It may be the display adaptor hardware in your PC? I assume its integrated into motherboard so do you have (or can borrow) a PCI display adaptor to test this theory? or better yet another computer or laptop you can test the monitor with to see if its the problem or its your PC... Good luck!

could be the graphics card, try a different driver, also try a different power cable for the monitor, very unlikely it is the cable but worth a try. If you have a nother graphics card you could try then try that, if problem still persists then it is your monitor, may still be under warranty, you may want to check that.

Right click on the desktop, go to properties, click the Screen Saver tab, then click Power. Where it says Turn off monitor, Select never. same with hard disks and system standby, put those on never.
