Re: Blank monitor on startup
Make sure the video card is secure
and monitor plugged in properly
does it shut down or you just get a black screen.
you can remove the card and if you have a different slot use it
then restart and see what happens
also are you saying you have dual harddrives
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

are you using a usb keyboard? A lot of systems require a ps/2 (purple round connector) keyboard to access the bios settings and anything on the startup screen unless you have set usb on boot in the bios settings. I would try connecting a ps/2 keyboard and see if it helps.
OK you have to re-setup your BIOS get into your BIOS and select "Default Configuration" and save then reboot. This MAY get you back. Removing the battery is NOT a great idea unless you have a specific thing to do with the BIOS. If you have a manual you need to read the section on your BIOS and the correct settings to make it function, removing that will "Reset" all settings to blank. Accordingly the PC must be set up all again, as if it just built.
You didn't indicate why? you did this?
Could be a problem with your system BIOS, enter the setup while your computer is booting (before it gets to windows) by hitting the F12 key probably. Make sure that the boot order is HDD first, not something else.
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.
i think this will help.
please rate my solution.
have a nice day.
Can you get into the BIOS setup? Usually, it will say "For Setup Press Fn" when you start booting up. When you get into the setup, look for a menu item that deals with "onboard video". Set it to disable. Then "Save and Exit" the BIOS. The new video board should allow you to view the screen, at a reduced resolution, until you load the new software.
Does it have on board graphics(built into the motherboard) If you are trying to install a different video card, then you need to set it up.
Hook the monitor up to the old one with the new one plugged in Look on the screen on startup for a SETUP or BIOS button(Usually F1, F10, or DEL) then go to ADVANCED and look for anything having to do with VIDEO, then if it gives you a list, with the new card listed, choose the new one. Then restart with the monitor hooked up to the new card.
