problem with computer not recognizing monitor need major help

[aetava]

Hello I just got a new pretty much barebone computer and me and my friend installed all the parts and when we hit the power, everything seems to work but the screen doesn't show anything. The hard drive is brand new with no OS on it. Anyone have tips?

Try any other monitor?

New monitor? If it is, it could be a defect.
New graphics card? That too could be a defect.

Old monitor? Try it on another computer to see if it works.
No/old graphics card? Try onboard instead and/or try another graphics card that you know works.
Does the monitor show any kinds of life in it? (meaning, does the black light come on?)

does the screen light turn a solid color at all or does it stay blinking?

you need to get into the bios and have the computer boot from a cd/dvd/blu-ray drive and then insert the windows disk, restart, and install the operating system.
