Using HDMI cable, no signal after windows 7 startup

[tommy11]

hi,
this is my computer specs:

monitor : LG 22ls4r
cpu : i7 2600
mb : intel dh67bl
vga ati radeon 5670
4gb ram
1tb hard disk
psu seasonic m12 520w

as I Have mentioned, when I tried using the HDMI cable, it worked fine till startup. however, after that it does not display anything (no signal) but I still could hear the windows sound.

anyone knows how to fix that?

try using dvi? if still no response then there is something wrong with the monitor / gpu. Did you get a new part that made this happen?

Also could be that your computer is trying to boot into a resolution that your monitor doesn't like. Can you boot into safe mode? Low res mode?

everything works fine if i use DVI, its just when I used HDMI cable, it runs till windows startup but after that it shows nothing.

the HDMI cable also works fine, I have tried my laptop to a tv

havent tried yet, but I use the same resolution for both HDMI and DVI. it works well in DVI
