Check the powersupply unit. if the unit does not take load there is no display. the psu will on but does not have the capacity to boost the power to the mother board. please check changing it

hook monitor cable back to your onboard video port then 1st make sure you have already downloaded the driver for your new graphics card. then at start up go into system setup and go to your display and make sure that you have your new graphics card enabled as your primary graphics instead of onboard video. it will say something like 1.Onboard 2. AGP/OR PCI MAKE SURE YOU DONT HAVE YOUR ONBOARD ENABLED AS YOUR PRIMARY VIDEO. AFTER THAT JUST SAVE AND EXIT THE JUST HOLD POWER BUTTON DOWN TILL PC SHUTS DOWN THEN SWITCH YOUR CABLE MONITOR CABLE FROM THE ONBOARD TO THE AGP/PCI CARD THEN RESTART YOUR PC. THEN YOUR PC WILL SAY FOUND NEW DATA AND WILL INSTALL THE DRIVER YOU HAVE DOWNLOADED FOR IT THEN YOU SHOULD BE OK IF THE CARD IS COMPATIBLE WITH THE MOTHERBOARD
Please expalin how you know "drives are good" (sic) As it would appear to me that this is indeed your problem? Unless as you say the video card has turned up it's toes. As you said the best way to check that is to enable the onboard Video and check, exactly what happens when you do that? Yes it will automatically use the video, it would install a generic video driver,and show video, are you sure the monitor is OK,have you swapped it out? Simply removing the Video card will automatically enable the onboard video, so you won't need to get inro BIOS. Check the RAM too, and remove any other cards in it.
this is most likely a pc hardware issue and not a problem with the monitor itself.
1. check cables and power switches.
2. remove devices from power strip and then plug them back in one by one.
3. try alternating memory sticks to diagnose if one may be bad.
4. remove pci dial up modem card.
5. if you have an agb, pci, or pci-e video card remove it and plug monitor onto the onboard video if the option is present. if not test with a known good video card.
6. if possible test pc power supply with known good power supply as it may have gone bad.
any damaged piece of hardware could potentially cause a system to not post or display to a monitor check these first as they may be the most likely culprits.
Did you add a video card? If you have an AGP slot, it is best to put the video card in it. If so you need to go into the Device manager. Remove, disable or uninstall the onboard VGA driver. Go ahead and remove the PCI video card driver as well. Power down PC. Make sure monitor is hooked up to the Video Card, not onboard VGA. Power on PC. When Windows loads, it should detect the VGA card first, but if it detects the onboard first, ignore and don't setup onboard first. When Windows detects the card, load the necessary drivers when prompted. There is no need to reinstall the onboard driver for the video unless you wish to hook up two monitors.
Sounds like your monitor is not getting any signal. The monitor is probably working fine its the video card or connection that is having the problem. Check all cables, then check to make sure video card is working. Does your computer POST without any problems when you turn it on? Do you have an onboard video port and a AGP/PCI-e/PCI video port? If so, is your video connected to the onboard or the AGP/PCI-e/PCI
You mentioned that you disabled the on-board graphics card using the device mamager.
You should disable the on-board video card in the BIOS.
Go to the BIOS config and disable the Video.
Some iiyama's have 2 inputs. One DVI and one analog. Also, some of the older ones used BNC connectors. What I'm getting at is make sure you have the right input selected in the monitor's menu.
Hope this helps....JF
