Monitor gets display only in windows.

0 votes

Monitor trouble.  I have an older CRT monitor. When I turn my computer and monitor on I see the bios post information flash by on the screen.  After that the monitor is blank even when the computer is fully booted and windows is loaded.  I need to turn the monitor off/on in order to get a display.  I see nothing after the BIOS post so it is difficult to boot from a bootable CD because I don’t see the text “press any key to boot from CD.”  Do I need a new monitor? Or is there a setting somewhere I not aware of.


Here are my system specs.


OS: Windows 7 Home Premium

Motherboard: Asus P5E3 Premium WiFi

BIOS: American Megatrends v0605

Video Card: Radeon HD 4870

Monitor Dell P1230 (22”)

This sounds to me like a bios setting.  Perhaps there is a setting that makes it do a "fast boot" and doesn't leave you much time to go into the BIOS. Try hitting the ESC key or F9 (which are common keys to get into the BIOS) right after the computer is turned on.  Now once you get into the BIOS you can then change the boot order of your PC.  I would change it so that it it will look for your CD-ROM/DVD drive to boot first.  Nowadays it's also common to even set USB devices to boot even before the optical drive.

But it also could be your monitor- perhaps it is taking longer to "warm up" and then display the screen, and by that time Windows is already booting.  The only way really to test that is to plug on another monitor and see.  You can also try another connection such as DVI (use an adapter to convert to VGA) if your video card has one, and see if it makes a difference.
