computer monitor won't work

[sammee]

so basically i can turn it on, then when i turn the monitor on it shows a black screen

monitor display
VGA - no signal input
> DVI - no signal input

the arrow is pointing to the dvi option, when i use a vga cable. after this shows for about 5 seconds, the screen goes black and says 'monitor is going to sleep' then it stays black after that. when it used to work, it used to have something on vga saying that's what i use and just start up normally. i don't even remember anymore, my computer hasn't been in use for over a year because of this issue. i want to fix it because it's still a reasonably good computer.  i've tried things like unplugging all the cords then putting them all back in and turning it back on and it still continues to do this. i've even changed the vga cord but the problem still happens. it's a hp pavillion w1907, on windows vista if that helps?

also, i know the monitor works alright because i plugged it into my laptop and it showed everything clearly with no problems.

Have you tested the monitor on another computer?

The next step would be to try a known good video card.

Before trying a new card try reseating the old graphics card by taken it full out and placing it back in the slot, or is this onboard graphics on the motherboard? If it is try using a video card instead.

where can i find the graphics card?

This is an example of what a graphics card may look like.
What is the make and model of your computer?
Just in case, have you tried another cable?

I have tried all of that, and my monitor still won't work. It won't pick up a disc to install the video graphics card
